How to make 3d curve tangent or continuous to existing surface
Im new to catia however not new to modelling. I am trying to create a smooth continuous surface by making 1st and 2nd vertices of 3d curve in the pic tangent to the surface.
My second question as I discovered is that I made a split surface by using plane as cutting element. After the operation was done I just moved the plane slightly down and the split surface became invisible. I can see the surface when I double click the split operation on the tree but not when I close it. The split is the last operation in the attached file
