With regard to the STL Exporter for Revit Platform, we got some great feedback the other day:
Hello,
My name is Erik Tremain and I am a graduate architecture student at Washington State University. I have recently been enjoying the STL exporter for Revit, and I want to thank you for creating such a thing because the luxury is priceless. Anyways, the past week I have put together two detail models and had them printed using the FDM process. Currently one model is dissolving in a 'support removal' bath, and the other finished printing this afternoon. Being that these two models came out so well, I am wanting to do a larger, spatial model that I can display alongside the detail models. While working on the two previous models I realized that the scale does not change upon changing the drawings scale in Revit.
My question is, at what scale are the .stl files being made? I noticed that the models are not 1-1, but I cannot nail down the exact scale.
Thank you for your time and I appreciate the hard work.

Revit Building QA Analyst, Zachary Kron, replied:
Regardless of settings in Revit, the STL exporter will always send out your file in feet (a 2000mm long wall will be 6.56 units, a 10 foot wall will be 10 units.) So, to make the scale for your final product, you will need to scale it based on a conversion from feet at the time of import into your secondary application. Thanks for the feedback and the images. We hope you continue to enjoy the tool.
Responding to feedback regarding 3D printing of Revit models is alive in the lab.
P.S. I have since added this information to the Autodesk Labs site page: http://labs.autodesk.com/utilities/revit_stl/.
