Trying to get this component drawn into altium:
https://www.molex.com/molex/products/part-detail/pcb_headers/0039303035
It has 3 pins which are the electrical connections but then there is also the two additional holes for the mounting feature.
I have attached the mechanical drawing for ease of understanding:
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.
Downloading the cad from octopart uses the same method (multilayer non plated hole), that is something i can't directly import in.
This is what the octopart import looks like:
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.

So? Name the pads "0", "MH0" (for mounting hole), or something like it. As long as the schematic symbol doesn't have those "0" pins, they will simply be unconnected. We do it like that all the time.
