Set the Z elevation of the start and end points of all lines to 0 (or whatever elevation you want).Select all of the Line entities we just created.

In most cases if I wanted to convert 3D to 2D, I’d do this: I have had troubles with FLATTEN in the past however, because I think it does some odd stuff sometimes with merging lines and approximating… so I tend to avoid it where possible. The FLATTEN command is an option for making the polyline flat (i.e., visibly the same as before, but drawn as a 2D line on whatever UCS you’re working on).

Both the LWPolyline and the Polyline only permit the creation of geometry on a flat plane (UCS), but the 3D polyline allows points anywhere in 3D space.Ĭonverting between the various types therefore has obvious difficulty, because going from 3D to 2D means you’re going to have to remove some of the 3D information from the polyline, and AutoCAD® could interpret how to do this in many ways. The third polyline type is the 3D polyline, which as the name implies is a 3D version. Chances are though, unless you’re working on some nasty generated drawing, you’re probably using LWPolylines. 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. There are various polyline types in AutoCAD®, the most common of which is usually the LWPolyline (lightweight polyline).
