You could just grab a PCB that size and put parts on it at their correct locations and it will be that part.
Do you want all views, or just one of the views in detailed. That is not going to be that easy if you want BB view - PCB view will be easier, but it’s still a weird shape -. Basically can you do a vector drawing of that PCB shape.
The curx of parts is that you draw a svg of the part, then on the top layer you add pins. Grouping is another story, ie, BB and SCH has 1 group, but PCB has special groups.
