The outer rectangle you can see in the svg attached and the workspace.

Another issue for the Shaper Origin: Unclosed paths… the rectangle I exported consists of four straight lines, not a closed rectangle. This is a showstopper for the Shaper Origin… A shape (which it is not as of now) like this rectangle won’t be good for anything than engraving the four lines as a line, no outside or inside routing possible.
