Create 3D solids from primitives or by combining or extending existing objects.
Start with standard shapes known as solid primitives to create boxes, cones, cylinders, spheres, tori (donuts), wedges, and pyramids.
Use the same techniques you use to create polylines to create a polysolid object.
Create new composite 3D objects or slice objects to divide them.
Find areas where 3D solids or surfaces intersect or overlap.
