Hopefully this helps someone.
I have been using this module for years, and have recently been getting really frustrated with the module crashing after apparently importing all the files.
Today was the last straw, after manually importing over 120 components, Sketchup crashed. Then the same again when I tried a second time.
This is it. This module NEEDS to be fixed - so I debugged it.
The line that is causing my system to crash is this:
[183] model.active_view.refresh
Comment this line out (#) and then the module works fine.
Hopefully this helps some one out there, or if a mod could update the ruby script (no update since 2015).
