What about with this one?

- Michael

im afraid this is worse - when I click done on the nut dialogue it just locks up MOI

MOI v4
Mac OS 11.6.

Hi Matt, it's working fine for me over here using MoI v4 on macOS 10.15.7

When you say lock up do you mean spinning beach ball? Can you use Activity Monitor to do a spin dump and send it to me at moi@moi3d.com ?

Thanks, - Michael

Hi Matt, I also just tested it with v4 on macOS 12.1and it is working fine for me there too.

If you can generate a spin dump maybe that will give me a clue for what is getting stuck on your machine in particular.

I also tested on Big Sur OS 11.2.3 and it was working for me there as well.

Hi Matt, ok the problem is the script won't work well when you have units set to meters. That makes the pieces that the script makes to be very small numerically and booleans can have difficulty intersecting pieces that are too near the default 0.001 fitting tolerance.

So set units to cm or mm to use this script, then you can copy/paste it into your file with units = meters.
