Having problems in subtracting

@boogyfat said in Having problems in subtracting:
I am trying to subtract a radial array from a cylinder. At the bottom of the screen it says Subtract - Classify Faces 2 and stays there. The blue line starts but never finishes. I started this project over twice and gets stuck here both times.

Are you using the Mac build? Regrettably we have not gotten the new subtraction library working on Mac so it does not work as robustly as the PC. If you have access to a PC you can try to do it there. It might not work though. Subtracting two meshes is an incredibly difficult problem and sometime it just doesn't work right.

I have been using the software for a few months now and have come across this many times. I've had to recreate parts in order to subtract them. The latest case involves subtracting a group of 3 simple objects (2.5x4x6mm) from a group of 7 simple objects (4x8x7mm). Even after I recreated the two groups, it took a very long time (20 minutes or so) to subtract. It also combined a thin triangle from the subtracting group into the other group and I had a hard time removing it (had to use a very small cube and it took 4 minutes or so to finish). I'm using Windows 10 64bit and have had these problems across at least 3 versions now (including the latest). It seems to help by not using translation and having no nested groups.

@treyjazz
Thank you for the feedback.
Could you also let us know the version number of MatterControl you are using?

@erikescudero 2.19.7.10353 stable. Here is a copy of the lastest part I am working on that is giving me the problem if the .mcx formatting is the problem.
