This previous post on using a Microsoft Kinect in Revit generated quite a bit of interest. Do you want to get more involved with Dynamo? Quote:
… go to the Dynamo site on gitHub, download the source or the executeables and open an issue if there’s a feature you’d like to see implemented. I’m in the process of putting together a tutorial for how to create your own nodes. In the meantime, if you’re a developer and you want to take a crack at coding your own components for Dynamo drop me an email, and I’d be happy to help you get up and running.
From the gitHub page:
Dynamo: Visual Programming for Revit
This project was started by Ian Keough. The intent of this project is to provide a code playground for building interesting parametric functionality on top of that already offered by Revit, and to do so with a graphical interface that allows you to share your work with others less inclined to write code themselves.
