I need to input a conic surface (hyperbola) into SW. I have been searching for a way to do this by inputting the vertex radii and the conic constant, but there dosent seem to be a direct way to enter this into SW.

I know about the xyz point table file which is an indirect method I might use if nothing else works.

Has anyone found a way to input a conic surface by entering the vertex radii and conic constant?

The conic constant is an optics term which is equal to the negative of the eccentricity squared - FYI
