Placing my embedded boards in position as per the dxf layout 6. Selecting the dxf outline, Design -> Board Shape -> Define from selected objects. Importing the outline into Altium into the Routing layer (which will become the board outline layer when gerbers are created) 4. Drawing the panel outline in Solidworks including the mousebite bridges 2.

It would be a LOT easier just to add a frame and be done with it, but I want to work out how I can create a frameless embedded board array (with an irregular outline) that can be submitted to JLCPCB for fabrication. That gave me a PCB that followed the outline of my panel (doesn't recognise any interior cutouts from the dxf though, and you can't select them from the dxf when using the Design -> Board Shape -> Define Board Cutout either), however if you then try the Design -> Board Shape -> Create Primitives from Board Shape it totally ignores the board shape that you just created, and creates the routing path based on the embedded board outlines. I then selected the outline, and Design -> Board Shape -> Define from selected objects. Is there a way to automatically trace the board outline onto a mechanical layer though, or would one have to redraw it manually? I tried creating the panel layout including mousebites in solidworks, then exported it as a dxf, which I imported into a new mechanical layer in altium.
