Hi Matthew, yes I see what you mean - yeah when you export edges each edge will be an individual curve piece in the export.

That's because there are many cases where there are more than 2 edges that touch each other at one point in a solid. Like for example the corner of a box has 3 edges that come together at a single point, not just 2 edges touching each other.

Also edges of surfaces are automatically broken up into separate edges where they have sharp corners in them.


So that's another reason why probably won't want to make surfaces out of planar curves if you just want to export already 2D curves, if you export just the curves themselves you should get a fillable result when you have a closed joined curve.
