Use lines and curves to extrude, sweep, loft, and revolve 3D solids, surfaces, and NURBS surfaces.
Understand the differences between creating solids and surfaces with the EXTRUDE, SWEEP, LOFT, and REVOLVE commands.
Create a 3D solid or surface by stretching curves into 3D space.
Create a 3D solid or surface by sweeping a profile along a path.
Create a 3D solid or surface by lofting a profile through a set of two or more cross-section profiles.
