      May I easily convert a 3D object into a 2D object?

      Once I have the desired perspective and angle of the 3D object, it would be easier for me to work with it as a 2D object in SU.

        Your question sounds ambiguous, would you care to elaborate?

            Exported object as a dwg and imported it as a flat, 2D object. I would like only the profile, the outer boundaries of the flat image and the ability to color it with a material fill.

              It's possible to do it without any extensions. You just need to clean up the edges where there are overruns and gaps so a face can be formed.

              Your model would be easier to work with if you'd turn off Length Snapping.

                Dave R, thank you, but I was hoping for a solution that was a little less tedious.

                Good advice. It is much easier to work with Length Snapping turned off.

                  Understood. Many of the forks in the perimeter edges require decisions that a Ruby script can't make. Which leg of the fork gets deleted and which is kept.

                    I haven't tried it, but Tig's Shadow Projector may be the trick for this.
                    Position the object perpendicular to the sun and project the shadow to become geometry.

                      Good thought. I just tried it. After about 5 minutes of processing I got a Bug Splat. Manually fixing the outline might have taken as much as a minute. Didn't time it when I did it.

                        Nothing like a good thought though. πŸ’š

                          Indeed! If the 3D object was simpler it would work.
