The following is a minimal reproducible example. FCStd file is also attached.
- Create a spline curve by sketcher with denser control points on one side.
- Create a spline curve by sketcher with denser control points on the other side. Place this sketch at z=30.
- Create a ruled surface between the two curves. When viewed from the front, it shows strange wrinkles.
- The cause of the wrinkles is visible on hidden line mode. It shows that the parts of the curve with denser control points are connected.
