This function allows the user to create a surface by sweeping a pattern (a selected line) along another direction line. The sweep direction follows the direction of the direction line.
• There are two types of SWEEP operations:
1. NORMAL SWEEP
The section line rotates along the normal direction of the direction line while sweeping.
2. RIGID SWEEP
The section line does not rotate while sweeping.
• The procedure of selecting lines is similar to those described in Section 5.2.1.
