Sirebel, I can export it to the following files. Maybe you're familiar to one of them.

.dwf

.dwfx

.fbx (tried different encodings, but it turns into gibberish in text format)

.dwg (AutoCAD native format)

.wmf

.sat

.eps

.iges

.igs

.dxx

.stl

If I understood you correctly, you want a new format because you can't open the fbx file in text format? I'm using Notepad++.

The problem is that vanilla AutoCAD doesn't have a built-in function to generate a centerline between two polylines, so I'm going after 3rd party lisp routines, that are either having severe performance issues (seems to be offline now), or not working as expected.
