Sweep command creates a solid by sweeping a profile along a

specified path.

Path

Profile (2D sketch)

A sweep feature requires two sketches;

a profileand a path.

The two sketches (profile and path)

cannot lie on the same plane or be

parallel.

The path can be either open or

closed profile. It could lie on oneplane or lie on multiple planes (3D

sketch)
