There has to be an easy way to do this but I’ll be darned if I can figure it out. Searching has gotten me a few close hits - but no cigar.
I need to project the shadow (sharp edged) of an object (say, a 3d blob) onto a planar surface and then linearly extrude that outline to become another 3d object. I can’t use a cut section because of the irregular shape of the object.
What I’m I missing?
