Hello all,

When I extrude a sinusoidal curve, I receive a jagged one with extra boundaries I don’t know how to get rid of them. I've also tried to change relative and absolute tolerances but there is no change yet. Could you please help me? I've attached two pictures for better understanding.

Many thanks

I've seen figures like that before. I think you are simply seeing graphic artifacts. Try meshing the surface -- you might find that the jaggedness disappears (except for the usual mesh discreteness). Also, consider changing the graphics quality/resolution display settings under Preferences. You probably have it set at normal. Change it to fine, and take another look.

Dear Robert,

After meshing I cannot see any change yet. I've also changed the quality from normal to fine. What else do you suggest?

Kind regards
