The community has the following notes at:

- it may help to use the OVERKILL command to eliminate any overlapping or intersecting paths before exporting from AUTOCAD
- if lines have different elevations, use FLATTEN [https://www.reddit.com/r/cad/comments/77x98n/whats_the_best_way_in_autocad_to_make_line/dopkmlj/]
- PLINES are intrinsically joined, and should be used where appropriate [https://www.reddit.com/r/cad/comments/77x98n/whats_the_best_way_in_autocad_to_make_line/doph35g/]
- AutoCAD 2000 DXF format (model geometry only, base model scaling) export from the desired face (not isometric view)
- 2004 Lines
For DraftSight: CHANGE > all > Properties > elevation > 0. This sets the elevation of all elements to zero (makes Z equal to zero).
