Hello,
does anyone know, why the boolean cut in the attached example fails?
I want to make a cage for a simple M4 nut. I have the model for the M4 nut and want to subtract it from a simple solid block, but with a little clearance margin.
So I used the Part->3D-Offset to make a little 0,5 mm offset (with the option for straigt intersecting faces).
The padded nut looks fine, but when I do the boolean cut (select first the Block1 and then the Offset-Nut), the cut fails. (Without an explicit error message.)
What is really strange: if I delete the 3D-Offset, and do the boolean cut with just the plain M4 nut, the cut succedes!
How can this be fixed to work with the offset, because I need the little wiggle room to fit the two parts together afterwards. I know, I could simply draw a scetch of the hex nut (or use a projection), but the workflow with the padding and boolean cut just seems the most elegant way.
Thank you in advance for any hints!
