Odd DXF behavior in Lightburn, from Solidworks files

If I import your file without auto-join enabled, it looks correct, but there’s at least two copies of everything, likely because you’re exporting the front and back faces of a model from a view, instead of extracting a single set of profile outlines and exporting that.

It shouldn’t be doing the weird lines to infinity though - I’ve reproduced that here and will figure out why and fix that.

For now, if you set the DXF auto-close value to zero, import, Edit > Delete Duplicates, and then Edit > Auto-Join, it behaves. The duplicate looped shapes overlapping are confusing the code that tries to connect it all together.
