Okay, thanks.

I'd only ever want to use the remove.

If you "Hide" pin 2 then the Pin Qty in the Footprint Name would be -3_4
The last pin number in the final footprint will always appear last.
So when you "Hide" Pin-2 you have a 3-Pin package and Pin-4 is the last Pin number.
 
If you "Delete" pin 2 then the Pin Qty in the Footprint Name would be -4_3
This means you have 3-Pins in a 4-pin package and Pin-3 is the last Pin number.

I wondered generally how people treat a DPAK where pin 2 has been cut off such as:

Do you enter it as:

TO254P1419X457-3_4

or

TO508P1419X457-3

?

I've been using TO254P1419X457-3_4 since I'm looking for the pitch of 2.54mm which is what the dimensioned drawing shows.]]> Wed, 05 Dec 2012 06:59:40 +0000 https://www.PCBLibraries.com/forum/to254p1419x4573-4-or-to508p1419x4573_topic734_post2578.html#2578
