Sweep
Solid|Create|Sweep
Uses a 2D profile to sweep after a line. A 2D profile can be a circle, polygon or an ellipse. First, you choose a line (it has to be a polyline without point differences in the breaking points), then, a cross section profile (has to be a closed polyline that doesn't have any insofar direction). If the profile is a polygone which contains a hole, a solid profile with hole will be created.
You choose how the solid object will be displayed, according to the standard display of the solid objects.
Choose original data - if the lines and cross-sectional profile should be deleted or not.
