A compound profile is an open or closed chain of connected curves or lines, or any set of closed curves or closed polylines. You can use compound profiles when you do not want to create a polyline, or convert a chain into a polyline. Compound profiles can be used as paths for sweeps etc., and as profiles that are swept along paths. You can use blocks as compound profiles, however there are restrictions. You can only only use one element in a block as a path for any given operation. Also, only closed sequences of curves, lines etc. (chains) or closed objects can be used to sweep, revolve etc. All such closed objects in the block selected to sweep, revolve, etc will used in the resulting 3D object.
