Create 3D solids and surfaces 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.
Use existing lines and curves to define both the profile and path for the solid or surface.
Convert existing objects to 3D solids.
Convert existing objects to surfaces.
Create new composite 3D objects or slice objects to divide them.
Find areas where 3D solids or surfaces intersect or overlap.
