The Sweep1 command fits a surface through a series of profile curves that define the surface cross-sections and one curve that defines a surface edge.
Steps
Select a single rail curve.
Select cross-section curves in the order that the surface will pass through them. When multiple closed cross-section curves are selected, there will be an extra step for adjusting curve seams.
Tips
Cross-section curves with the same structure create a better sweep surface. Cross-section curves will have the same structure if they are all copied from the same curve.
If the cross-section curves do not have the same structure, use the Rebuild cross sections or Refit cross sections options. The rebuilt or refitted copies of the cross-section curves will be used to sweep.
When Refit rail is enabled, the refitting tolerance is controlled by Document Properties -> Units -> Absolute tolerance.
