OK here is a new part. Turns out I was wrong, you probably couldn’t make this easily the third row causes an issue in pcb:
even with the finest (8mil) traces DRC won’t pass to run wires in to the middle pin. Luckily I had already solved this issue for a RaspberryPI GPIO connector and can use the same bits here:
Note in both cases I needed to set the grid size to 0.05in from the default 0.1in to get the wires routed between the pins. On the final part with 16mil traces default DRC passes:
and finally the part:
male-header-15-pins-3row.fzpz (12.5 KB)
I’ll note in passing, if making new parts from any of headers, the generic IC or the mystery part it is vital to change the family name in the .fzp file (or in the metadata in the Parts editor) because the standard family name will trip internal processing and allow Inspector to modify your part with unfortunate results.
