Pipe3D is an AutoLisp program that draws a 3D pipeline in AutoCAD.
It is especially useful at examining if there is a coincidence in
pipelines. The pipeline contains n turning points (including
beginning and ending points), which determine (n - 1) linear pipe
sections (some may have zero length!) and (n - 2) bendings between
the linear sections.
Pipe3D is free for private users.
