catia v5r19

Good morning. I should build a surface with two different profiles, which is guided by a curve and must be constant to a reference surface. Do you have ideas about how to do that? Thank you.

Good morning, I draw simple geometries with catia v5r19 I realized that the view is not exactly orthogonal. I better explain: if I design a simple circular section cable cylinder and put myself in the orthogonal view at the base, I see the cylinder shrink, I see the inner surface. how can I do...
