Thanks for the response Richard. The problem is I have other 4 pin connectors
in the part table so I can't add two more pins unless I move this connector to
the conn6 folder. Right? If I do that my concern is the engineer won't find
it but I guess after I tell them how it works they will learn to live with it.
Again, I appreciate the help! -DC

You can add the GND pins as part of the total pin count as shown below in red.
They just don't stand out as gnd pins but that is common. If your schematic
symbol is a single instance with just pin A on it you won't have to change it.
Then add the non mechanical padstacks/pins to the footprint.
FILE_TYPE=LIBRARY_PARTS;
primitive 'CONN4_AL1';
pin
'A'<0>:
PIN_NUMBER='(1,2,3,4,5,6)';
BIDIRECTIONAL='TRUE';
INPUT_LOAD='(-0.01,0.01)';
OUTPUT_LOAD='(1.0,-1.0)';
end_pin;
body
PART_NAME='CONN4';
BODY_NAME='CONN04';
PHYS_DES_PREFIX='J';
CLASS='IO';
end_body;
end_primitive;
primitive 'CONN4_AL2';
pin

PIN_NUMBER='(1A,1B,2A,2B,1C,2C)';
BIDIRECTIONAL='TRUE';
INPUT_LOAD='(-0.01,0.01)';

Thanks for the reply Richard. I'm not sure if I did my connectors "correctly"
but my chips file looks like this: Maybe I was lead down the wrong path on my
connector creation. Changing them at this juncture would be extremely painful.
Is there any other options for me looking at my chips file? Thanks! -Dennis

Make them electrical call them G1 G2 Mechanical pins can't be used for
connections.
Here is a chips file example:

Subject: [PCB_FORUM] Connector Shield Pins
Hello All,
I'm using Allegro 16.5 with Design Entry HDL and I need to make
a USB connector that has 4 pins for signals but also has two pins that will tie
the shield to ground. My question is should these two shield pins be made
mechanical or connect pins? Thanks in advance for any advice on how to handle
this! -DC
