I would like to draw vectors on a surface. Here are some procedures of mine you can use. They should work with either Release 3 or 4. This comes up often enough that maybe I'll contribute them to the share library.
Any comments are welcome.
I've been keeping my eye on this group for a while now, in case this very topic came up. Yes, please contribute these to the share library. I'm thinking primarily of the 2-D case here. OK, it should be easier than the surface case.
