Project stray curve segments to nearby faces

(I have probably answered my own question in the subject header.)
Just something to think about:
Have you ever tried to draw or trace on a surface not on the ground plane, only to discover later that some of the segments are not in contact with the constructed surface?
What method would you use to make all of the segments lie completely on the surface? If you did not use Bezier tools, or Tools on Surface?

I would watch for "On face" messages as I draw and, I was drawing lines that should be parallel to the axes I'd make certain to keep them on axis as I draw.

Assuming I still ended up with lines that weren't on the face, I'd use Didier's projection plugin. I'd probably make a new face parallel to the original but at some distance so that after projecting all of the lines to the face, the original lines would be easy to delete.

Thanks, Dave:
I assume that I should orient the camera line of sight more or less perpendicular to the target surface?
I can tell you it ain't easy to use beziers or other curves in this program.

By the way, do you know of some good tutorials on use of curves? Especially, when to use bezier as opposed to fspline or catmull or cubic and so on.

You could orient the camera to a standard view and set it to Parallel Projection but I've never found that absolutely necessary. Watch for the On Face messages as you go. One thing I do with Bezier and other non-circular curves if I'm not already drawing on a face is draw a face to work on. I think of it as a piece of paper in the 3D space.

As far as tutorials for the various curve types and when to use which, I don't know of any. I think it sort of depends upon what you know about the location of the points for the curve. If you are just drawing the curve out of your head, it probably doesn't matter much as long as you get what you want.

Thanks again.
