BNC bulkhead footprint (D hole)

[eliocor]

Being new to Altium, I have LOTS of things to learn...
One for all is how to define the mounting hole for a BNC bulkhead connector (to be mounted directly on the PCB): see attached pictures.
Any suggestion on how to define the hole like in the pictures (it should be metalized)?

Just define it in a mechanical layer. For metalization, you will have to talk to your board manufacturer and specifically negotiate this point.

Also, keep in mind that typical mill diameter is 2 mm, so you need to think hoe those sharp corners will end up, and plan for that.

draw on a mechanical layer , select the drawn elements and go to tools- > board -> create cutout.

I would prefer to define a component with the already defined cutout, instead of putting a PCB cutout after placing the component...
Any suitable suggestion?
What I would like is to define a "plated multi-layer pad" but with a shape different from "round/rect/slot"

Does it really have to be plated through?
I would have made a ring without soldermask on both sides and coupled with some via stitching. You can define cutout in footprint.
Easier and cheaper. Your fab house will likely charge plenty for an oddly shaped plated hole like that.

the via stitching is a reasonable option... Thanks

so? that is what i describe. store the cutout in the library itself.
anything you can do on the pcb you can throw in the library.

here is a little secret with altium : ANYTHING that can be created on the PCB can be copied into the library. the library editor itself has a few limitations in terms of editing capabilities, but NO restrictions as to what can be put into it... you can even store an entire board as a library element ...

i frequently create new components in the PCB editor itself. then select the primitives , open the library editor and simply paste them there ...

thanks for all suggestions, but as I wrote, I'm really a newbie regarding Altium and what it seems straightforward for you it is not so easy for me...
