Release 2.3 Misses Part of STL File

When I use release 2.3, the Contour ignores part of the tree branches.

When I use release 2.2, the Contour correctly follows the entire model.

Do you know what might be happening? Perhaps I’m doing something wrong. Or perhaps there is a bug. I don’t know which is the issue.

@danny_evans welcome and thanks for the report! if you don’t mind, please use profle -> export and check “include workspace” and email me the resulting .km file to

Thanks for the reply! I just sent an email with the file.

Great. Easy to replicate given this file. In the meantime, if you want to carve this before I make a fix, you can run a roughing pass with “inside only” and “clear faces”, then run the contour pass.

@danny_evans version 2.3.1 was pushed just now and it contains a fix for this. please let me know if it works for you.

Thank you! The update works great. This is very useful software; I appreciate you making it available.
