cosmetic hole colouring

Hello, All;

I'm trying to colour holes on our detail drawings. When I export an iges or try to open a solidworks file in Powermill, any hole that has a cosmetic thread shows up as grey, minus the bottom of the hole (if it's a blind hole) which has the proper colour.

Is there something I'm missing?

Here are some snips of what I'm talking about. The green detail is in solidworks and looks good, the grey detail is an iges opened in PC-DMIS that has the errors in hole colouring.

I also have the attached files here... I'm new to the forum, don't know what method is preferred.  https://imgur.com/a/QybZs8O
