The Building Coder Samples for Revit 2013

I've posted previously about the Revit SDK, which includes working code samples. Jeremy Tammik is a member of the AEC workgroup of the Autodesk Developer Network ADN DevTech team, providing developer support and other services. Well, over on Jeremy's The Building Coder blog, he often posts code snippets from his support calls for the benefit of the Revit community at large. Quite brilliant.

Today Jeremy posted that he had ported his "Building Coder Samples" to Revit 2013. That got my attention. He has samples? Yes - not only does he write posts on his blog, he keeps a running set of working samples to capture his work! And he provides it free to the Revit community with the source code! Now THAT'S brilliant!

When loaded, a RvtSamples panel is added to the Add-ins tab. It contains two pulldown buttons, one labeled A-M and the other N-Z.

I couldn't find a  handy listing of the sample commands on Jeremy's blog so I wrote a quick little VB.net app to strip them out of his include file. Here are the rather extensive results (command names followed by descriptions):
