I am trying to design a PCB with an odd shaped cutout in the center. I am using the 'Solid Region' tool, and I switched the 'Attributes' to 'Board Cutout' and 'Multi-Layer'. When I select the 3D view, the cutout shows up nicely. However, after downloading the Production files and uploading to JLCPCB the cutout is not present anymore. I would appreciate any help with this. Thanks much in advance!
