Since I was one to vote yes on the poll I will be the one to make the first post here too.
If you are a user of Green Building Studio (or plan to be at some point) you might want to take a look at this white paper. It gives some tips and best practices for creating a Revit model to get good results out of Green Building Studio. Some of the steps to getting a good model might not necessarily be in your current workflow or thought process when modeling for construction documents. This document will cover some simple alterations you can make to your Revit model so you can achieve the best results.
The white paper can be downloaded from the following link. (Too big to attach here)
