View Full Version : creating surfaces from a nonplanar curve

So, here goes the question:

How do i create a surface from a single closed non-planar curve?
(ex: a circle that doesn't have the edit points in the same plane)

Boundary doesn't work because it requires over 3 curves. Planar works only for planar curves.

I know there are work-arounds like dividing the curve into more than 3 subcurves and using Boundary, but i was wondering if it can be done directly.

I know rhino can do it. Does maya?

Thank you.

its not going to work with planar is it? i wouldn't think so because its non planar.
try cutting it up into the necessary curves and trying boundary or square. Four equal cuts should work nicely.

you could duplicate the original closed curve. then scale it so its real small. then loft between the two generating a new surface. then delete the history on the object. and now snap all the points in the middle to a central point within the surface to try and close it out visually in the middle.

this may be too many steps to get this, and it may not be the solution you're looking for, but there is no tool off the shelf in Maya that will do what what you are requesting at the click of a button . . . sorry.

good luck.

PS - you could always try to write a tool that will accomplish this at the click of a button :) or just use the boundary tool.
