Hi Karsten.

This project? mMM Rubik cube ? mmm nope. Its furniture that I want to cnc.

I will try with your script. The strange thing is ...I am not understanding how am I getting naked edges...when I am using the rials and profiles of intersections...

I am not imagining how a sweep can leave gaps...if i am sharing the rials (???)

Anyway when you say they are not well connected...is this affecting the fillet or exporting...or both.
