Section Type Rollout (Sweep Modifier)
The Section Type rollout lets you choose either a built-in, stock section or a section based on a custom shape.
Interpolation Rollout (Sweep Modifier)
The controls on the Interpolation rollout of the Sweep modifier work exactly as they do for any other spline. However, the controls affect only the built-in section you've chosen, not the spline that the section is swept along.
Parameters Rollouts for Various Section Types (Sweep Modifier)
The Parameters rollout is context-sensitive and displays different settings depending upon the built-in section you've chosen to sweep along a spline. For example, more complex sections such as the Angle have seven settings that you can change, whereas the Quarter-Round has only one setting.
