Adding Custom Properties to a Part

I'm trying to add a macro to automate adding custom properties
to a part files.   As you can see in the
video, the macro recorder seems to be getting hung up.  I have never done API programming, but a
little BASIC years ago.  I’m started
using “CADSharp.com” yesterday. I’m not looking to learn a lot of VBA at this
time, other than getting this macro to work.
