[Anonymous]

Hello all. I have a set of 3 stl files that are in a specific arrangement, and i want to know if meshmixer can combine them into one stl file. basically, merge them into a solid?

thanks

Yes it can.

Shift+click each one, then select 'Combine'. Then export it.

that was fast haha. ok, i will try it out now and see if it works. Is there a way to make sure it creates a "solid" with no errors?

ok, i tried it, and now each piece is a different color. What does that mean?

thanks

The colours are facegroups

To make it watertight (solid)
