ABSTRACT
3D polyline A 3D polyline is a continuous object created in 3D space. It is similar to a 2D polyline, but does not possess the 2D versatility, i.e. there are no variable width or arc options available with a 3D polyline. The benefit of a 3D polyline is that it allows x,y,z coordinates to be used. A 2D polyline can only be created in the plane of the current UCS.
