Alignment Specifies whether the profile is aligned to be normal to the tangent
direction of the sweep path.
NOTE If the profile is not perpendicular (normal) to the tangent of the start point
of the path, then the profile automatically aligns. Enter No at the alignment prompt
to prevent this.
Base Point Specifies a base point for the objects to be swept.
Scale Specifies a scale factor for a sweep operation. The scale factor is uniformly
applied to the objects that are swept from the start to the end of the sweep
path.
■ Reference. Scales the selected objects based on the length you reference
by picking points or entering values.
Twist Sets a twist angle for the objects being swept. The twist angle specifies
the amount of rotation along the entire length of the sweep path.
■ Bank. Specifies whether the curve(s) being swept will naturally bank (rotate)
along a 3D sweep path (3D polyline, spline, or helix).
