Has anyone written an AutoLISP macro for Uniform B-Splines.

I'm not sure if this form of a spline can do it, but does somone have an AutoLISP routine they would like to share that approximates equally spaced vertices on a spline or polyline?

Thanks in advance,

I don't have one, but it should be writeable. On either a spline or polyline, you can use both the divide and measure commands to place points along them. You can't add vertices to a spline, so you would have to feed those point to a routine to draw a new one. You could add new vertices at those points to a polyline.

Dave, thanks for that function I wasn't even aware of. There's a boat meshing program I've written mentioned in an earlier post on 12/17/03 that this should cure:
