Why do the results of Sweep2 frequently have discontinuities in curvature (multiknots) when the input rails and sections are smooth? My expectation is smooth input should result in smooth output.
Example: Sweep2ExampleA.3dm (77.7 KB)
Rails are single span, 4 control point degree 3 curves.
3 sections are straight lines.
Result is a 39 x 2 control point surface with multiknots at 9 locations.
