Thicken Generator
Adding extra dimension to models is easy thanks to the new Thicken Generator and modeling tool.
Add a shell around existing polygons to solidify your model. Thickness can be generated inside, outside or centered on the existing mesh, and an advanced algorithm resolves intersections while preserving perpendicular edges and corners. In the Thickness generator, you can control thickness based on a polygon selection or vertex map, and selection tags are generated automatically for the shell and each cap.
