I don't see a way to create a complex board outline in Circuit Studio. There are only freehand tools, no CAD type tools for outline / mounting holes. Are there tools - am I missing something?
Thanks,
Charlie
For mounting holes, I just place a through-hole pad with the pad size set to the same as the hole size and no designator. I believe that is the most common approach but could be wrong.
You can design a mounting hole as a component that is just a through hole pad. Then add clearances and keepouts as needed (for screw heads, washers, tool access, etc). You can build up a library of these for #4, #6, M3, M2.5, etc fasteners or for plated and non-plated mounting holes. IPC-7351 has a naming convention for mounting holes that makes it somewhat easy to assign and then figure out what these are.
Once you have a schematic library and footprint library you can put the mounting holes on the schematic and then treat them like any component in the process. This lets you have an electrical connection to a mounting hole if you want to use it for chassis ground.
