The Building Coder releasing updated code for several applications for Revit 2017, including Revit Lookup.
One might notice that Jeremy only releases source code on GitHub, and not compiled applications:
I think this is likely because Jeremy works for Autodesk, and compiled applications would have an implied warranty. It's liability mitigation in other words, and that's totally understandable to me.
If you want Jeremy's Revit Lookup 2017 but don't want the hassle of compiling it, Harry Mattison of Boost Your BIM has done the work for you. Read about it here.
Thanks Harry, and Jeremy!
