The (Revit) thoughts that come with a fever. AKA: Trumping the 'In Place Revit Family: The Floor' post ...Even if I suggested it.

So Hello there once again. I posted in last week's (In Place Revit Family: The Floor) that we can create a metal deck (looking) floor with an in place family. Well, that's true enough but it (the in-place family aspect) kept bothering me (not really) since for one, the in place floor won't be cut by an opening such as a shaft, it won't have multiple materials, etc. Actually it seems that this stuff really does bother me, because yesterday while sleeping off the flu I woke up at about 1 am and realized something that seems blatantly obvious now...Create a normal floor and use an in place generic 'void' family and cut that from the floor!!! Then the floor will be a real floor having all the flooriness we have come to love from Revit floors, including the ability to be cut, have materials etc. MULTIPLE YAAY!!!

1. Create a floor (NOT SHOWN)... I think we can all do that, right?
2. Next, From an elevation view (perpendicular to the desired deck direction) GoTo MODELING/CREATE and choose Generic Model...(this will make the in place kind, remember?)
3. On the Modeling Tools choose "Void Form" and if you need the metal pan similar to the one I used choose the Void Extrusion... In order to draw the lines delineating the decks 'corrugation' I picked the floor plane that is staring at me (from the elevation view). 'Tab' may need to be employed to get the correct face... don't choose the top of the floor!!!

4. Next, using those lines (obviously) draw the shape to be voided out of the floor.
5. Just before finishing the family make sure the extrusion is long enough to cut the entire length of the floor in question, then using the "Cut Geometry" tool...
Cut the void from the floor. Finish the family and now a better "voilà"
Oh and as you can see from above a normal shaft opening cuts our floor...A truly elegant solution. Thanks Revit!!!

Name, Rename & More from a Revit Schedule

First, I want to get something out of the way: distinguishing the differences between "simple" and "easy".

Using Revit is easy (especially when we 'Use Revit like Revit'
Using Revit is not simple.

Anyone who says Revit is simple is either full of shit or has no grasp of the words meaning. (And: I apologize if I ever said or intimated that Revit is simple...If I did say that it's simple then I'd like to clarify and say it's easy...mostly, not simple). Sorry folks, there is no "push button Architecture" Nothing comes from no work!!!

WTF do I mean? Well let's see what Merriam Webster says about:
Easy:
1 a: causing or involving little difficulty or discomfort (Like when Revit and the user are both at their best)
3 a: marked by peace and comfort (Like when Revit and the user are both at their best)

Simple:
4 a: lacking in knowledge or expertise ('Can't get much done in Architecture, etc. that way)
5 b: free of secondary complications (Doesn't sound like Revit...or Life...)

NOW that that's over with here is an easy way to Name, Rename (or More) views or sheets, etc.

Use a Revit Schedule! Actually we use 'View Lists' and 'Drawing Lists' (we must use the VIEW/NEW...per the image below, because these are some of the few items NOT on a Tool Bar)

Uhhh by the way, Autodesk, do you see the symbol that you call an Elevation marker? It's simple (and as long as you keep it around so are you...Please change it!!!) -Is it insane of me to speak toward a corporation as if it's a person??? Better yet a person who is listening to me!!!

Back to business...
The issue herein is that I needed to change a whole bunch of views' names.

If I am editing objects that can be seen in the model then I tile the appropriate view(s) along side the schedules and work from the schedule to then make wholesale, or multiple changes...thus the easy...not to mention faster, better & more Revit-like way). YEEEHAAA, using Revit like Revit.

The Image Below:
1: What needs to be Renamed.
2: Why we need to Rename it.
3: Painful to Rename more than a few views from the Project Browser (PB).
Plus there are more clicks to get to information to/from the PB than can be at our fingertips from a schedule...On Demand Information (ODI for the TLA folks) I like it!!!
...the info, not the TLA's...
4: The solution of choice. If you need to Rename or add info then type the info once, CTRL+C then just click and paste (CTRL+V) to rename... But what I needed, as illustrated below was easier...I just had to click/select (one step if you're a bit careful) and delete the now useless info...
The moral of the story is: If it can be scheduled then it can be changed from a schedule; Easily.

Makes sense when we see it like that, doesn't it??? Revit Like Revit.

In Place Revit Family: The Floor

Well, I have been asked to show a colleague how to create a metal deck floor. YAAY!!!

First I asked the user (as you should ask yourself) if they (or you) actually needed it in the model or will illustrating the corrugation in a detail suffice: refraining from modeling this floor would keep the file smaller, more flexible and a bit more streamlined to edit, etc.

Well, the answer came back that they want it in the model, so here we go...
First I created a bogus project to illustrate the following procedures: I already have levels and grids so defining Work Planes will be simple: I will use Grid J (Hey, what a nice coincidence).

The 'Project' waiting for the 'floor'.
On the Modeling Tools choose 'Create'. This will begin the create an "In-Place-Family" portion of our show.
Choose "Floors" (somewhat obvious since we want to create a floor). This is going to make our In-Place-Family a Floor Family. Always remember that when creating any kind of family (In-Place or Component) you must choose a category; if one does not correspond to the object you are creating then use "Generic Models".
Name the family...Be specific so you can tell it apart from others you create!!! BTW: "Floor 1" is probably something I'd NEVER use on an actual project...you know, do as I say, not as I do...(a day without hypocrisy is a day of hypocrisy)...???...
Now we're ready to model. For this we'll use a "Solid Extrusion" for the body of the floor.
Set the Work Plane (as I said I am using Grid J...Nice name...)
When I choose a grid, in order to draw perpendicularly to the plan view we are in (if we are in one) Revit will ask us to open a corresponding Elevation or Section View, so know your views!!!
Also remember to set the depth of the extrusion to a depth that will make it easy to see, you can stretch it's depth into final placement, easily enough, later on. I find it best, in many cases to stretch extrusions later (rather than calculating them up front) as it also makes locking it, much simpler.

7) Now that we're in 'sketch mode' draw the actual profile needed. Lines? How quaint...
When you're done drawing the extrusion's profile then "Finish Sketch" but don't Finish Family, yet. We still need to create a few voids (or would you prefer to use shaft openings? Well good luck getting shaft openings to cut the In-Place Floor: let me know how that works for you...if you try it).

BTW: notice I am stretching the extrusion length in the image below, right? You would lock it if needed.
Now create any Void Extrusions necessary. Note: I made them -2'-0" since they begin at the level and need to cut downward. Also the wedge shape needed to be a separate void and needed to leverage the Cut Geometry tool. Your results will vary, this is one of the times CTRL+Z becomes handy, quite possibly...

When you finish the voids then finish the family...and...voilà:

A Metal Deck Floor...Well OK maybe we didn't make the materials 'metal' (yet) but you get the point...Right?

Take Care,
-J

Revit Error Reporting: Again, Just Do It!!!

Well it happens to everyone sometimes: An Unrecoverable Error Has Occured... UGHHH. If (when) this does happen please send those error reports!!! it's not just to give you a feeling that ADSK is working for you; they actually want to fix the issue and when they do it helps all of us!!!

On their site, there is this page relating to the explanations and this link is a cute (not really) picture illustrating what happens to these messages.

On with the show: "After the Crash" and yes, I saved a recovery file...

Use the following dialog to help ADSK help us!!! See image 3 as well but please use the "Step by Step Description" area to give as much info to them as possible (I know you're busy but if you want ADSK to get rid of the issue you experience you have to let them know what was happening. Take pains to communicate... or at least say something...


Image 1 below is the "details" page for your edification & paranoia abatement.


Image 2 below is the "What Happens" web page...



Image 3 below is their helpful hints as to what kind of info helps them help us:

Finally: Image 4 below is (I hope) obvious enough...


In an odd way I have always felt a little better after receiving the following 'thank you' from ADSK... It is almost (ALMOST) like I never had a problem whatsoever...
AAAHHHHHH, now isn't that better???

The Greening of Architectural Production: Using Revit like Revit

Using Revit like Revit? WTF? What a concept.

It's actually a bigger issue than many imagine. Additionally this concept seems not to be so obvious to everyone using Revit (maybe misusing?), or possibly worse yet, it may not be obvious to those implementing or considering implementing Revit.

I try to follow these guidelines when using Revit:
Use Revit Like Revit.
Do what I Know how to do.
Learn what I don't know that I don't know.
Incorporate.
Repeat.

Revit As Revit
There are actually 2 main concepts here:

1) "Using Revit like Revit". This one's in our personal & Professional scope.
Modeling what's appropriate, When appropriate, not trying to force CAD strategies on a BIM solution. Just because it seems to be a comfortable or viable position to use CAD strategies often it's not. Even if Autodesk says (or intimates) it works really well (such as using...even exploding (YIKES) AutoCAD files in Revit)...What are your AutoCAD angular tolerances set to??? -We'll talk about this later...

The following is a serious, friendly warning: IF YOU EXPLODE .DWG FILES DIRECTLY INTO A WORKING PROJECT THEN I HOPE YOU WANT TO LIVE WITH A TON OF FUCKED UP GEOMETRY, NAMES AND MORE THAN LIKELY NUMEROUS, POSSIBLY HUNDREDS OF ERRORS & WARNINGS.

2) "Revit working like Revit".
This one's in Autodesk's Professional scope.
Although it sometimes requires our guiding, nudging, pleading, ____ing of Autodesk to more fully develop Revit so that it works like Revit; -Or at least so it works like their sales force & Marketing Materials & fAQ's say it does.

In regards to #1: It has been my experience that trying to use Revit in ways similar to whateverCAD, or using Revit with or based on whateverCAD processes usually leads to a great deal of pain that in most cases can be avoided by just using Revit like Revit. Even if you have to learn how to use Revit more fully and even if there are new pains using Revit...The fascist UI for instance.

Want an example? Well, it seems to be logical for some users to think that linking (or worse Importing) all of their AutoCAD base files, or details (etc.) into their Revit Project(s) is a useful approach... especially since this work flow is actually spoken about as being viable by agents of or around Autodesk. I say Yikes!!! (Yes we may in the short-term need to leverage SOME cad files) but it should be known that using a lot of .dwg files, both when Linked and even more so when Imported, will cause undue file bloating & slow-down, plus all those 'slightly off axis' line errors...OOOHHH they're a lot of fun...

I'm (tongue in cheek) guessing some this CAD compatible work flow came from ADSK being gun-shy after they freaked a lot of Architects out by releasing & pushing ADT well before it was (in my opinion) able to deliver anything near it's promise. If you want to Detail in Revit and you're considering using WhateverCAD then click me first!!! It was a good idea to build in these .dwg integrations (obviously, since everyone isn't using Revit yet) and since .dwg is the current Industry standard. Well I will ask again -where are those hand drafters anymore?" along with the dinosaurs, all CAD will go away one day and BIM will replace it, and so on...Right now at least it's time to get over CAD as fast as possible so our expertice in producing our Artform doesn't go through undue pain and waste...it's kind of like The Greening of Architectural Production.

I submit (and have seen) that an over-leveraging of linked and/or imported (yuck) CAD files is an approach that, in most every case is avoidable and has lead users down a rabbit hole that has lead to Revit-Hell.

In relation to the Detailing example: if you have 1-10 details then OK, fine, I won't argue with anyone in using CAD files there (well, yes I will) but if you have 25 or 50 or 100 or more details in your set, or more importantly if you will ever want to use those (or similar) details again, in future Revit projects, then I would not recommend linking CAD details whatsoever. Just Recreate them.

If you already have cad files that you want to turn into a Revit Model and you think that the lines that 'say' they are 180.00 degrees are actually that; well try changing the Angular Units Precision, in your CAD software, out to 8 decimal places (Just humor me on this and try it)...It is a very good chance (I'd say an overwhelming chance the more production people you work with) that there are some (or Many) lines nowhere near correct. Not a big deal if a line is out .0004989 from being truly straight??? If you are out a fraction of a degree and you are drawing far from 0,0,0 in cad, maybe due to required setups and you need to Rotate True North once in Revit, you can (or will) be creating coordination nightmares for yourself and others: AND isn't this why we use Revit, to lessen those errors and coordination gaps and lack of correct geometry? It is for me. I always hated the dimension override, I found it proved to mostly be just an excuse to be lazy or sloppy.

In regards to #2: How can it be, you ask, that Revit doesn't work like Revit? After all, things simply work how they work. OK, I'll give you that point on semantics: but what I mean (to mean) is that it's not so much that Revit doesn't work like Revit works; it's more that Revit doesn't (always) work like Autodesk professes or intimates that it works. Ahhhh, That's more to the point.

A portion of the response to FAQ 1, on Autodesk's own site states:
"...Revit® Architecture software is a complete, discipline-specific building design and documentation system supporting all phases of design and construction documentation..."

Complete? That may be stretching more than the truth...more like pulling my leg. If Revit was complete (even in and of itself) Autodesk would stop developing it and we'd stop asking for more. And the modeling would be tolerable (Nice Loft tool). And the UI wouldn't be so fucking Fascist. And the dialogs (when you are say 7 boxes deep) would allow an 'accept & close all' type of action. And. And. And.

We are at a place where we seem to have to help Autodesk to "get it's mind right" so to speak, in regards to the development of Revit. I quote that because I find there are areas and methods designed into Revit that make it 'Not Revit Like' at all; you know? Things that seem incomplete, illogical or inappropriate and frankly antithetical to how a real "Complete BIM Solution" would work. Now I know that nothing can be perfect (and yet everything is perfect, just how it is and isn't)... but I'd like to see a new, more perfect perfect Revit.

So, now we can get back onto the business of ourselves: of Using Revit Like Revit. It may seem like we can use protocols from other modeling softwares in Revit, but we can't always do that. Don't use Masses for Components. Don't use cad files if you can at all help it. Work smart, take ownership and most of all think before you act. This last point is no joke; many times taking a few minutes and talking with several people about a possible approach or task may (and usually does) reveal hidden or even unknown possibilities. At worst it'll prove your methods sound.

I was going to start to compile a list of things I'd like to see incorporated into Revit but I have already sent them directly to Autodesk so I'll end with a simple (simple for me) request:

Come on Autodesk: you know what you need to do. After all, even you tried to get Sketch Up (allegedly). I am not saying that Revit modeling should be like Sketch Up's modeling (am I? No, it should be better.) but would it be so bad to make modeling any shape that Architects can imagine at least possible without a degree in Astral Physics? Can't it be at least as complete as the new 3D in AutoCAD or better yet Rhino? OOOH he said the R word. I know we can link these programs' 3D .DWG's into Revit, but the problem is they don't work predictably or completely like Revit Masses and the translation out to/from .dwg can break things and...what??? Nurbs? What?

You get the point. (s)

Sloping Floor & Roof Slabs in Revit

Remember THIS POST? It pertained to sloping Floor & Roof slabs. Well it seems that I should clarify this new functionality a bit (or just my posting...although I do remember being told by 'agents' at ADSK that there is (now was I guess) the limitation of these things (at this time is we need to begin with slabs having only non-curving boundaries, only, in order to get these new tools to work. Well, the slabs don't need to begin as purely rectangles they just need to be bounded by non-curving lines. At this time they also need to satisfy the following scenarios from RAC 2008's build ...1700's Help:

..."These tools can be used to slope a constant thickness slab or the top surface of a slab with a variable thickness layer in order to model the following scenarios:

• A constant thickness slab or roof supported by sloped non-planar framing.
• A variable thickness material used to slope the surface of a horizontal plane (for example, tapered insulation).

In order for shape editing tools to be activated the following conditions must be met:

• Slabs must be flat and horizontal with straight-edged boundaries.
• Roofs cannot be attached to another roof, and the roof cannot be a curtain roof. If either of these conditions is not met, the slab shape edit buttons do not display.
  NOTE:if these conditions are violated later, by some edit to the element, then the slab shape edit will cause an error with a callback allowing the user to reset the slab shape edit."...

Since we're not able to use the new tools with curved boundary slabs the opening command and/ or the void element as cutting objects are still in play...

Converting CAD Details To Revit Details: Just Do It...One way or another.

Before you read on note that there is a companion to this (or as you may find a replacement)... RIGHT HERE... added 07-09-2010...

First off thanks to Nike for unknowingly letting me use their old slogan.

Secondly: Yes, the following are all 2D detailing methods for Revit!!! We can talk about leveraging our model for project specific details based off the 3D geometry later: that's a different diatribe... Also please note: All times are empirical estimates and are placed as general guides, to be used solely as approximations, as I have no way to know how your teams can or will perform, how detailed your details are, etc., etc... Now on with the show.

There is a question that seems to always come up about what to do with existing and/or typical CAD details in Revit. And that question is...What to do with existing and/or typical CAD details in Revit?

Do we redraw them (Can you say Intern?), do we Revitize them or maybe just Link the CAD files in and continue to edit them outside of Revit? Let's take a look at these options, shall we?

• Plan A: The "In a perfect world" approach. -Draw (and/or redraw) all details entirely in Revit.
• Ensures the cleanest Revit geometry (hopefully). (This approach can be expected to yield the antithesis of what can happen in plan B when the CAD data is bad. For the results of some 'Bad CAD' data see Image 1).
• Details will be formatted and can be saved into project templates, pre placed on sheets and just waiting to be printed!!! Or we can use FILE / INSERT FROM FILE / VIEWS... for another method of propagating these, now existing views, into other current and future Revit projects.
• Devise a projected time line within which to accomplish this by. Remember; eat the elephant one bite at a time, it's the only way to manage this and not freak the whole office (or boss) out! An example is: If The office has 1,000 details (traveling West at 65 MPH) and Johnny manages a team of 5 users (and 3 of them play hockey) and each user draws 1 detail a day: When will they be in Chicago?...Uuummm I mean, when will they be finished? They will be complete before 1 year comes to pass [200 work days to be in Chicago...not bad]...Hey here's a good idea for a team vacation incentive: Complete the detail work in half the time agreed upon, while still getting 'the work' out. Details done, morale high.
  
• If you are on a 1-2 year plan to fully implement Revit then this method will help you enormously!!! Each detail should only take 1-4 hours once a good work flow is obtained. -Since these are quite often details that we already have elsewhere and we can print them...

• Plan B: The "In a nearly perfect world" approach. -Revitize CAD details that you already have. (See Images 2 through 10 below!!!).
• This consists of turning the CAD data into Revit data.
  
• If your CAD teams draw (in CAD) with 8 decimal place precision, and they are always drafting perfectly, mindful of their snaps, etc., etc., etc., then what's shown in Image 1 will never happen, making this Plan = or > Plan A.
• BUT!!! If your CAD teams draw with 1, 2, even 4 decimal place precision then all bets are off and I can almost guarantee that you will see errors! In the cases where Plan B yields less than perfect results you need to Review Warnings!!! very carefully and often to ensure that no errors show up in your actual projects...PLEASE don't let that happen!!! (Remember this later when I talk about my "Paranoia Abatement Protocol" AKA: The Old Test Project...Don't Revitize a CAD detail without it!!!).
• Once a good work flow is obtained this could take 1/2 to 2 hours per detail.
• Details are now Revit formatted just as in Plan A.
• Devise a projected time line within which to accomplish Revitizing all CAD details by. My 'Chicago algorithm', the elephant and the 1-2 year plan benefits are all still applicable to this approach as well as for Plan A (Yaay)...Though the math for this option may be as little as half or better. Again, depending on the users, the CAD data, etc.
  
• Sounds enticing and maybe exciting...and perhaps it is. I suggest at least a test by the same Revit user, where they take 2 sets of similar details; maybe 3 details for each option. See which works best for you, your standards and your office...
  

The now famous 'Image 1'

• Plan C: The short-term, temporary or "Oh Shit, just get them out the door" approach. AKA: The "We'll get to it later" method.
• Link (not import) the actual CAD files into separate drafting views. Fast to link but could (will) pose more work when wanting lines to import 'correctly' etc...not the end of the world but if it's not already set up and you have to print NOW you're F#@*ed.
• Possible issues with text, leaders...But if it's "Oh Shit, just get them out the door" then we gotta do what we gotta do...
  
• When (or if) you use this method, remember that when you use the Detail Callout tool you will need to choose the "Reference other view" from the Options Bar & then pick the correct drafting view from the drop down list.
  
• Keep putting Plan A and/or Plan B on hold and you may find your teams are wasting so much time opening, panning, waiting that you schedule that in-house meeting where you, or others roll out the "Today we begin Revitizing all of our details" project..."Who would like to volunteer?...Yes Johnny, later is today"
• Obvious method for when the clients or planning commissions, etc. need info before it was planned and/or scheduled for.
  

The detail I used herein is very simplistic with few lines when compared to most construction details I have come across and still it generated 30 errors!!! (As seen in image 1) Yes, the 30 errors "(may be ignored)" but being that the lines are all "slightly off axis and may cause inaccuracies" that is just too much risk for my liking or for me to take into the future of my projects, if I can at all help it.

REVITIZING DETAILS EXPLAINED

• Begin a new, blank 'detail creation' project. (Not a real Project!!!)
  
• Create a new Drafting View.
• Name it now (it's best at this point, especially if you get into a "production line" mode. It can help make this Revitizing, transitioning faster.) we can always change the scale later.
• Open that view and Import the CAD file there. Image 2.
• Remember, Linking is Plan C, so make sure to Import.
• I inverted the colors and let all else be default.
• Leaving the CAD in color makes it easier for me to see what I have already changed and what I have yet to change...

Image 2

• Explode (full) See Revit Help and search for 'explode' to find all you...maybe...need to know.
• Note that by using partial explodes you may be able to shave a little more time off of this process, depending on the consistency of the CAD files, etc...
  
• Select all the linework and change it from the CAD's styles to one of Revit's own. Image 3.
• Usually I adjust the lineweights later in the final, clean, project version of the detail but that's your call.
  
• Convert in this same manner any CAD hatch patterns.
  

Image 3

• Convert in this same manner any CAD Text styles and recreate all leaders. Images 4 & 5.

Image 4

Image 5

Hide all (now Revit) text and leaders. Image 6.

Image 6

Delete all exploded CAD leaders and arrow head remnants. Image 7

Image 7

Unhide all hidden objects. Image 8.

Image 8

• Verify by selecting everything and hitting the 'filter' button. Image 9.
• If you only see Revit items listed then...
• Hit CTRL/C (Copy to clipboard).
• Now it's the time for the Paranoia Test.
• If you see legacy CAD names, etc. go back to the cleaning & converting until it's all clean, Revit geometry.

Image 9

THE PARANOIA TEST:

• Open another new, blank project.
• Create a new drafting view & open it.
  
• Its name doesn't matter here, since this is just for testing purposes.
• CTRL/V (Paste from clipboard).
• Here comes the test:
• Select everything and hit the filter...what do you see?
• If it's all Revit geometry, etc. then this detail is now safe for project use, if not then something slipped by, but don't worry: this extra little step disallowed your project from becoming muddied by CAD data.
  
• Image 10: the final detail with lineweights adjusted...

Image 10

Oh Shit, I nearly forgot: do you really want to F#@* up a Revit Project? Explode a lot or just one large CAD file directly into your project...Don't do it!!! It CAN be tracked!!!

Review Warnings. Do Not Ignore Them!!!

Just a quick reminder: REVIEW WARNINGS!!!

I am a sort of purist; being both an Architect (Officially when I complete the licensing tests later this year or next) and an Artist: So what does this mean, I am not so sure, only that being that 'purist' of sorts, when in Revit I work under the premise that No warning or error is a good one, so I get them resolved and keep them that way.

This is so important!!! I have even made RW the keyboard shortcut for it. My workflow with regards to these warnings is: if I don't see any on-screen warnings I still check at least 2-3 times in the morning and another 2-3 times in the afternoon. (I am sometimes so focused that the on-screen dialogs slip past, without me noticing (or caring, for the time being). On the other hand if I do see warning dialogs and still choose to TEMPORARILY ignore them I will RW ASAP and resolve every issue!!!

In my travels implementing Revit with multiple project teams, especially where many users are somewhat new to Revit I have found that there is a tendency to get quite surprised at the amount of Errors they have allowed (Yes, Allowed!!!) in their projects.

Best practice alert: Resolve warnings as soon as they come up!!! And when they do come up click the button pointed out subtly below.


These errors and warnings can lead to bloated file sizes and possible file corruption, as well as the dreaded lost project time spent fixing them, usually after hours. The good thing is that this should be a self-teaching-lesson for users: once they have to fix 200 or 800 or 3, 000 (See This AUGI Thread) they should have learned this lesson (or they may need "that" talk in the conference room, or office, with the door closed).

Now, if you have done this in the past you may have found it to be a pain in the ass since the dialogue box closes after each warning is resolved; If that is the case then Here's a link you'll probably love!!! It's another great resource for a more user-friendly way of dealing with these warnings. (Update for 2009: There is now an export function natively in the Revit warning dialog box, so use it!!!)

BTW: If you RW and your computer Beeps or just flat out ignores you that's a good thing: it actually means you have no unresolved warnings. YAAY.

Scared yet??? Get over it and work smart (er), This isn't Autocad!!! where sloppy drafting is mostly just an annoyance (BTW Autocad users: do you know "overkill"???)

Viva la revolution...Uhhh...I mean, Happy 4th of July & Be safe!!!

Midnight Ridazz, Schedules and BIM?

Art, Architecture, BIM, schedules, families, blocks, parameters, details or anything else we do at work or in life for that matter; can be quite empty, if we don't have some fun!!! So, if you live in Los Angeles (or anywhere near) I suggest that you block out a few hours (depending on what kind and how much "fun" you want to have) on the second Friday of each month. The Midnight Ridazz' bike rides usually start about 9:30-10 pm and go past Midnight (obviously). Everyone is welcome!!!

How much fun is it? well when 300 to 1,000 or so bicyclists get together for a group ride throughout the city, taking over the streets and riding to great music, it is more fun than can be explained with mere words...even the uphill portions are fun; 'cause you know what follows "up", right? ...No, not puke... it's "down"...

Yes, that's me on the left and a good friend & another Ridazz veteran on the right: we're just about to enter the 3rd Street tunnel below the 110 FWY. BTW: the people on the left sidewalk got up and screamed along with us...or maybe at us, I'm not so sure...

So, when I yell Midnight Ridazz, you scream: Ride on...and make it loud!!!

Save a tree, ride a bike!

The New Revit Build is Here, The New Revit Build is Here!!!

First off: Here Is the newest Revit Architecture 2008 Build (as of the original date of this posting, of course).

I was asked by a rather good Revit user if I could help them and figure out why some (yes, only some) of their project's Plan Callouts would disappear when the view it lived in was cropped. "Hmmm", I said -"OK" (well I really didn't say that but you get my point...Back to business): I spent a little while going through the usual questions...are any relevant Worksets off, any filters, you know all the "who, what and where's" that seemed relevant; I checked VV...No, not VG that "G" is too far for me to move my finger to!!!. Finally, after nothing brought it back, ouside of not cropping the view (in this case that was unacceptable) I just recreated a new Callout and that one showed up as expected. (Typical).

Now at this point I could have suggested there was some error, whether it be the dreaded and all-too-often cited Operator error, the many-times-true: Windows Memory Leak (did you like the "plus signs" disappearing from the Project Browser? That WAS a Windows Memory Leak), or even the sometimes erroneous, sometimes not: Computer Error; etc. but I just couldn't get that original Callout to work correctly so I knew it was a bug. Well, at the time I thought it was a bug but I didn't find that out until doing a little (and I mean little) external (outside of Revit) research.

I won't say (yes I will) that I Google'd the following: "Revit Callout views disappear in cropped views" and promptly got a hit (actually the third result on the first page of results!) of: someone else with that very same error, only in Structure. Well my instinct was validated; it was (Yes, I just said WAS and not IS) a bug in Revit. Now, If you forgot why this posting is important, or why I am writing this at all: here is the point... WE ALL NEED TO KEEP UP WITH THE MOST CURRENT BUILDS AS SOON AS WE CAN GET THEM!!! Now you can't say you weren't told.

Keeping up with the newest builds, along with contacting as many resources as possible whenever you have an issue (with Revit) is a good method and maybe even the only one we have, to get our issues (with Revit) addressed and resolved. Hmmm, Issues...

Now I just wish that I could change that fucking elevation marker and duplicate more than one view at a time...Oh Shit J, don't get me started!!!

Color Scheme Legends and True Colors

Ok, post 3 of 3 for today. WOW I was up late last night, going off on idiot computers...Too much BBQ perhaps.

So you say you want to use Pantone (R) colors, or RGB color values for object's surfaces, etc. in Revit (maybe to get a finish color without rendering???) and you want to have the colors actually print correctly (or as near to correct as is possible for your system's hardware)? Well this little trick has been gleaned and can be used to get the output you require, though there may be (is) the need to test the different settings out a few times, to get them "just right"; depending on your printer's calibration (or lack thereof). -Please do small test prints at the final output quality and save a tree (AND your ink!!!)

OK. To begin with (assuming there are already objects that have surface patterns that are set to having a 'solid fill' and said solid fill is set to a color other than black or white!!!) set the following via "Advanced model Graphics" (found where we turn our shadows on) to the following settings:

1) Shaded With Edges (Note: Perhaps it is the case that these views are for inclusion into CD sets: In that case many (or most) other objects will probably NOT want to have colored surfaces for these specialized views...)
2) Cast Shadows checked
3) Sun (between 85% & 99%)
4) Shadows Off (unless you want them on, but this posting is mainly to get colors correct in hidden line views)

Have fun and be sure to share your experiences to forward the expert use of Revit. Also: think long and hard on this one...maybe even talk to the entire team...It may take some management.

Oh, yeah, I left 'Override Silhouettes' out of this exercise since that doesn't affect the colors. But that too can be useful, especially when combined with shall I say, the line work tool and object overrides? Yes, I will... These few things should and will help us to get much richer, more illustrative BIM documents.

Integrated Practices...YAAY, Finally!!! When it actually happens en mass.

Today: 3 posts (this is the second) and it's a pretty good read from our friends at Architectural Record: One of my favorite quotes from it is: "...(BIM) is enabling— some say forcing—this information-sharing, integrated-practice culture to emerge." Click me for the entire article.

OK: So "Today I Picked Flowers"

Well, Not really but this is going to be an 'Ideas Only' posting... While reading a fellow BIM Blogger's thoughts on Technocentrism (Thanks JN) I had these thoughts. I hope they apply, here ' goes:

BIM too will be surpassed one day by something more brilliant...the only constant is that all Architecture and Engineering solutions (at least the great ones, in my opinion) are born out of imagination. The technology available at the time is merely what we'll use to communicate those ideas so they can be paid for and maybe even built.

Now, BIM software may help us in those endeavors but it will not make the ideas for us and although we can program in mathematics, formulas, parameters, etc. to solve problems or even to generate shapes, etc. the computer is still quite dumb (They have no creativity!!! And that's what ALL the Arts take)...

As, I believe, Picasso said of computers: "...But they are useless. They can only give you answers". Any idiot (sorry idiots) can use PhotoShop, etc. to apply a watercolor or impressionist or cubist 'effect' but no computer will ever come up with those movements on their own, let alone in context to society or fractions of societies.

So BIM or CAD or even BIM-VS-CAD should be seen like the pencil overtaking the pen or scratching in the dirt...it's just a new (maybe better...definitely better!!!) but still just a tool; another way to illustrate our dreams so they can be manifest into 'reality', such as it is. It didn't take computers (as far as we know) to design any of the pyramids around the world and look at their impact on civilizations. Nor were Gaudí's forms realized on computer...it will always be genius (or some close approximation) that generates Art, let alone Art of any great impact. I just hope some of the buildings (and Art) we are now creating don't make us, as a society, look like idiots (sorry again) who are blindly applying an effect or two, or ten... and then thinking that's somehow worth the toilet paper it would be printed on.

Viva la imaginación.

Revit File Sizes: Some ideas...

Bouncing around Augi I found this paragraph (Sans Additions) from the 'Diary of a Revit User: Purge Party - May 2007' article particularly intriguing (see below). As I am putting together a presentation on Revit regarding The Appropriateness of Content (or lack thereof). This presentation will deal with when to place items, when not to, why different approaches get different results, etc. Well as I said the following is kinda interesting:

"...First off, a Revit user must ensure that a minimal understanding of modeling and project file size have been achieved before beginning a Revit project. (No Shit...I couldn't agree more!!!) The user would then understand the implications of developing a model without populating it with unnecessary elements. (Hopefully) Secondly, the user must understand the basic differences between linking information and importing information. (The difference between Playing with and watching!?) Each method is equally important; however, if the model is to be developed so as not to end up being in a position to spring clean, then the proper choices must be made before introducing external information into the project file..." (As it is with everything in life...Good thing we have 'purge' in Revit...I know I could use that in my life from time to time!!!)

Well, That's it for now, the kids need to get to bed, I need to email my hockey team and well, that's enough for now...Work Intelligent (ly)!!!

Revit Architecture 2008 2: More on Roofs & Floor Enhancements...Revit Structure Too!!!

Slope to drain...Now we can for real!!! (Unfortunately there is no automatic tag that will report the slopes (yet?)).

Perhaps you recall the tools or maybe not; either way they are found on the Options Bar after you select the Floor or Roof (just to the right of 'edit').

So; below is a 'flat' Roof with a few Ref Planes placed for us to snap the 'split lines' to.After creating a flat roof select it and the new buttons reveal themselves. The next step for this exercise is to delineate the ridges, valleys, etc. for our desired drainage (or just to design a complex object, etc.) for this we use the 'split lines' button.
The next two images were taken in the midst of drawing the 'split lines' at each vertical Ref Plane, then corner-to-corner.After we place all the 'split lines' required select the points at the intersections and tap into the number and set it (them) at the appropriate (negative ?) relative height (s), as illustrated above.
If you already hit escape, or need to adjust those points in the future then you can always use the 'modify sub elements' button.
Some of the new parameters added to allow much of this new functionality is set from editing the' structure' of the Floor or Roof elements from their Type Parameters: for this I set the Insulation/Thermal layer to be the 'variable' one; Note that the finish layer above it automatically follows the now variable slopes of that underlaying sub-element.


(That's cool!!!)

Here is what that all looks like in a partial section:
Then in 3D:
And as promised: To get the (I know, rather unsightly...) shapes below I placed an eliptical shaft opening at one side and created a generic, in place 'void' family and used the cut the geometry tool to give the multiple curves at the other side. Don't worry, we can create beautiful shapes also!!! Although as shapes go (not roofs) this isn't that bad...Now with these new tools and functionalities I estimate there can now be even less lines drawn in our ever increasingly coordinated and BIMalistic (BIMtastic???) projects and world. Next maybe we'll look at the final new tool for roofs and floors...'Pick Supports'...yes we'll place structure for that!
