Continuing the discussion from Understanding why this Boolean Difference won’t work:
I am still having big problems with this. I have a small section of a wing that I am trying to subtract from a solid block, to leave a negative mould shape. I want to use this as a test piece to CNC mill, but I can’t get it to subtract. As per the previous thread, this is a regular problem and it’s going to cause me problems if I can’t find a way around it.
Using “What” it seems that the wing is a valid solid. So is the mould. No naked edges to be found. But the difference always fails. I’ve read a Rhino Wiki on solving the problem and I resorted to using Boolean Intersection, then Boolean split, but the split fails. You can see on the separate layer that I tried using a simple box as the mould, but it still won’t subtract.
Can anyone please help?? I really need to work out what the problem is that keeps happening because this is the most important thing that I want to be able to do (create negative moulds).
