@RTCEUR 2014 | Jay Zallan's Class Presentations and Downloads

Hello from Dublin -Yes, Ireland -Well when this publishes I will be en-route, so Hello from 35,0000' or so ;)

To get the RTCEUR 2014 thing going and to provide, for those unable to attend, a portion of 'the goods',  I am posting my class handouts, presentations and associated downloads and links.
I do hope you enjoy!!! -And get some value from them obviously :D

The video (that is obviously not in the pdf below) can be watched below or at: http://youtu.be/923jxZY2NPI 

The point of including this video is to speak to my point that 'reality' is relative to us humans and what we make of it and ourselves is really the only game we play.

I find it a wholly liberating concept that we may only be minor players, on a tiny spec in the cosmos, but that we can have large relative impact for one another!!! Therefore:
  • Let's Play Big, With Integrity and Always Strive to be The Best We Can Possibly Be!!! 
  • Liberate Your Own Greatness(es); That Will Both Inspire and Free Others to Liberate Their Own!!!

BIM Junkies' Life On The Lines

This is mainly to help me remember the way to negate the "Inconsistent Units" error but I am sure there are more people who will find this useful!!! From the real Revit master: (BTW: This can obviously be applied to many objects, not just walls as the example shows)...

"Let's assume that you are using Cost parameter available in Wall type as your unit cost. When you assign numeric value to to Cost Revit has no idea what is the meaning of this parameter. It could be cost per square foot, cost per square inch, cost per linear foot, cost per wall instance, etc. You are the only one who knows the meaning and you use your knowledge while writing a formula for calculated value in schedule. Revit just enforces that units of measurement are the same on the left and right sides of your formula.

Let say you want to compute TotalCost (number parameter) then taking into account the fact that unit Cost is also a number (no units of measurement) and Area parameter has units of length square you would write

If Cost is per square foot then TotalCost = Cost * Area / (1' * 1')
If Cost is per square inch then TotalCost = Cost * Area / (1" * 1")
If Cost is per square meter then TotalCost = Cost * Area / (1m * 1m)
If Cost is per linear foot then TotalCost = Cost * Length / (1')
If Cost is per wall instance then TotalCost = Cost

Makes sense?"
