Boolean Operations on non - solids
Posted: Fri Apr 10, 2015 3:17 am
Hi all
I decided to post this as it is not covered well in the documentation
Objects in a Boolean operation do not have to be solids. They can be some open surface with edges. This often is the case when the surface is a mesh coming form a 3D scanner. See the pictures. The subtract in the case is a way to generate a perfect orthotics
The main thing for the operation to be possible is that the intersection line of the two surfaces consists of (possibly several) closed lines. This is a more rare situation: When a line has ends the ends must lie on edges of both surfaces. So edges of the two surfaces must geometrically intersect in 3D
