plot vectors perpendicular to curved surface
How to plot vectors (e.g. presentation grid) so that the vertical axis become perpendicular to a curved surface? (Instead of always in the global horizontal and vertical axes).

Re: plot vectors perpendicular to curved surface
is this not possible?

Re: plot vectors perpendicular to curved surface
Not sure I understand the question. Here's what I think you're asking:
popt vect ugrid on spoint x,y,z, <a point on the surface snorm x,y,z <a vector normal to the surface view snorm rota x 90 repl If your asking about mapping your results to another coordinate system, you need: psys 5 < a csys with one axis normal to the surface getc all vmag repl

Thanks, but these didn't do what I wanted to see.
