Hello everybody,
I'm working with 3d polylines and I need a lisp to do this: to draw lines from some points perpendiculat to a 3d polyline. There are a lot of points, 3d points - I mean points in space, with Z different from 0. From each point to draw a perpendicular on 3d polyline, but on that part of poly that is closer to my point. Is it possible? Thanks!
