Here's a way I tried that seemed to work quite well.

In Scene browser, hide your solid part.

Then, move down to the Edges line and click the area where the eye icon resides. This will display a wireframe of the solid.

Still in scene browser, select all edges by moving to the right of the Edges line and clicking - so a yellow dot appears.

Press Ctrl-C folowed by Ctrl-V to copy and paste curve equivalents of the edges.

These curves can now be selected and exported at will to your other chosen application for further work or printing. I tried .dxf and .iges into ViaCAD and everything came through sweetly.
