Yes! I’m watching this with great interest. I goofed around with threads here
http://www.theswamp.org/index.php?topic=59402.0

There are still many road blocks.
1, most all of ObjectARX is not thread safe,
2, wxPython is not thread safe

However, this project should not block other modules that may be thread safe. I may make a test build someday just to test the behavior.

There’s a bit more I can do sans threading
1, bind with numpy at the C++ level to remove the need to convert some geometry classes to tuples, then to np.arrays
2, boost::python seems to make unnecessary copies. I want to try using move operations

This challenge was enlightening performance wise,

I could see the sweat on team .NET lol
