    Convert 3D Polyline to 2D Polyline There are various polyline types in AutoCAD®, the most common of which is usually the LWPolyline (lightweight polyline). It can be confusing because the LWPolyline and the old Polyline entity used way back in the early days of AutoCAD® are both shown as a “Polyline” in the Properties window.

    Is there lwpolyline in 3D?

    3D Polyline. This command creates a 3D Polyline. A 3D Polyline is a version of a polyline that can have different elevation at every vertex. 3D Polylines can not have arcs and the program will instead draw a series of short chords to closely follow an arc. The 3D Polyline command is available from the Draw pulldown menu, from the Draw toolbar or at the Command: line (3DP).
