How does it work if you have 3d rotations in your design? Say I create a 3d shape and then make 30 copies rotated at different angles, like in gear or a bracel

Wouldn’t the slices end up getting rotated out of plane?
- sebastos 8y agoYou can probably get the model to a place where the actual orientation / position of each component is completely resolved into the final world coordinate sit will have, then do the slicing after that but before any intersections / unions.
- bayesian_horse 8y agoNope. All slicers work by intersecting a plane with a 3D volume. In this case a CSG tree. At the bare minimum you need a way to tell if an x,y,z point is inside the volume or outside. In the case of a rotated cube shape, the x,y,z vector is just rotated/transformed the other way (inversely) than the cube, and the test still works. Most slicers will have more sophisticated methods of intersecting a plane with a volume...
