Apologies if this is covered elsewhere. I looked through the docs and didn’t see it.
I’m producing some parts for 3-D printing some of which will screw together and some be a push fit. Boolean differencing looks like a great solution (particularly elegant for the screw thread female component) but the advice from the printing company is to leave a gap, say 0.5mm, so that parts will actually push/screw together rather than having an exact sized component being too big to push in.
Is there a way to do this neatly in Rhino? I’m thinking of some made-up command like “Make this hollow cylinder in the solid 0.5mm bigger in radius but leave everything else in the solid unaltered”.
I’m wary of just dragging points in case I accidentally create an oval shape and parts start to fit badly.
Could you let me know what you think? Many thanks.
