If it happens to be a problem too often, it could be a good excuse for making a special Altium script, I suppose. At at least it's pretty obvious when 3d bodies and courtyard layer primitives end up in the wrong layers. Will have to see how well the new layer types feature actually works, in keeping this stuff together. Layer Types There are several layer types that can be specified when adding a mechanical layer. A shame that it seems these different settings are going to become the *default* for new Altium users, though. Even though older versions of Altium's PCB design software are limited to 32 mechanical layers, newer PCB files that contain more than 32 layers can be safely opened and edited in an older version. It shows a mechanical layer, and I tried to create a board shape on the mechanical layer. Layers are then stacked and plated to form staack blind/buried vias that allow access to any layer. Each layer is drilled either mechanically or with a laser. Stacking blind/buried vias in a multilayer board requires using a layer-by-layer process. So at least I can keep things inline with the rest of my parts lib for now, it's only using parts from other people using different settings to generate footprints that needs to be considered. Now I want a PCB border on Keep out layer, but Altium is not. This design strategy is called every-layer interconnect or any-layer HDI design. and mine seem set to what they have always been.

When using Gerber file, it is only used for text. have Altium changed the mech layer use for the IPC wizard? I hadn't noticed this yet - but I haven't used 18 or 19 that much, and may have only used it with my existing dblibs, come to think of it. Some board manufacturers use the mechanical layer to make the frame when using Altium file to production.
