Trying to get this component drawn into altium: https://www.molex.com/molex/products/part-detail/pcb_headers/0039303035
My issue is that i am unsure how to make the 2 mounting holes? I previously added them as multi layer non plated, but then it gives me an error if i don't have a designator (missing pad designator). But of course it's not a pad.
Any suggestions? Also i am finding different designs on octopart makes use of different mechanical layers. Is there any best practices for this? For e.g mech 1 for 3d only.
