There is a lot of inquiry about Revit addons and tools, beyond the OOTB capabilities. So in an attempt at compiling an exhaustive list this post may grow in the future. I have not tried them all so beware and use at your own risk; as always let us know the good/bad&ugly... FYI, this post is not going to deal with full applications such as green Building Studio, Ecotect, IES, E-Specs, etc., as those types of Apps stand on their own.
