Sweep

Ken Youssefi Introduction to Engineering – E10 3

Sweep command creates a solid by sweeping a profile along a

specified path.

Path

Profile (2D sketch)

A sweep feature requires two sketches;

a profile and a path. These two

sketches cannot lie on the same plane

or be parallel.

The path can be either open or

closed profile. It could lie on one

plane or lie on multiple planes (3D

sketch)
