About Sweep Surfaces in Style
Two elements are required to create a sweep surface:
• Trajectory—Curve or curves that guide the sweep.
• Cross-sectional sweep profile—Curve or curves that sweep along the trajectory.
There are two types of sweep surfaces:
• Profile intersects the trajectory
◦ One or two trajectories can be used.
◦ One or more cross-sectional curves of any type can be used.
1. Trajectory
2. One cross-sectional profile
• Profile does not intersect the trajectory
◦ Only one trajectory can be used.
◦ One or more cross-sectional curves can be used. The curves must be planar, and the plane on which the curves lie must intersect the trajectory.
