Thank you but I'm not researching about how the normal vector is computed at a point on surface. I'm just researching which way the laid down curve on the surfac support is achieved, when using a point-direction line but with a surface support.

You know, to know how CATIA...
Hello Tibix,
Thanks for your care about the subject.
Not normal, the line is used as the direction and would have any component of x, y, z.
Actuallay I'd like to know the methodoloy to achieve the computed curve on the surface.
Could you please explain how this is done by CATIA?
1. There is surface (S) and a point (P) on it. Also a line (L) that goes through the point (P).
2. In command line - point-direction type, select inputs above such that the surface (S) is the support and the line (L) is the direction...
3...
