How to import CAD into the board for special-shaped modeling

When importing the shape of the panel part using CAD, please note the following points:

1. It is recommended to draw with closed polylines, i.e., PL lines, and no separate straight segments should be present.
2. The shapes must not be blocks. If they are blocks, you need to explodethem by pressing X and then join them using J.
3. The CAD file must be in .dxf

After drawing the shape, drag the panel part from the material library, press B on the keyboard, right-click on the panel part, select Edit panel shape, click (Import CAD), and then save.
