Surface Sweep

You can create a sweep surface by a profile curve and a path curve. Click View, Geom Surface to toggle the display of individual surface.

To open sweep surface:

To create a sweep surface, select an edge or wire as profile curve, select an edge or wire as path curve. If you want to make a circle as profile, check "Circle as Profile". Select a FEM beam as path, check "Pick Beam as Path".

You can check "End Constraint" to make profile curve connected with path curve on one end. If the path curve is noisy, you can also check "Smooth Path" to make the path smooth. To set surface continuity, check "Set Continuity".

"Fix Coordinate System" and "Scale" are the options to control the shape during sweeping.

a. using a circle as profile, a helix curve as path curve, get a sweep surface
b. result by check "End Constraint"
a. The path curve (brown) is a C0 curve
b. Sweep surface setting continuity as C0
