p...head,
When you inport the dxf into LC and then clean it, you should see that there is a rapid to each closed section, if not,SETUP>Loading Option.... and set the
connection line tolerance to 0.0001". Then re-inport the drawing and see if there is are rapids to all the closed sections.
A few pics attached showing that it imports fine, then i just did machining of the circular outlines, tried doing an outside offset and seems its trashing a few circles.
You can select individual closed section and define the machining.....
Not sure what you are trying to do with it.
