Make them electrical call them G1 G2 Mechanical pins can't be used for
connections.
Here is a chips file example:
FILE_TYPE=LIBRARY_PARTS;
primitive 'CONN4_USB_TYPEB_4GNDLOC_4PIN';
pin
'G1':
PIN_NUMBER='(G1)';
PINUSE='POWER';
'G2':
PIN_NUMBER='(G2)';
PINUSE='POWER';
'3':
PIN_NUMBER='(3)';
PINUSE='UNSPEC';
NO_LOAD_CHECK='Both';
NO_IO_CHECK='Both';
ALLOW_CONNECT='TRUE';
'1':
PIN_NUMBER='(1)';
PINUSE='UNSPEC';
NO_LOAD_CHECK='Both';
NO_IO_CHECK='Both';
ALLOW_CONNECT='TRUE';
'4':
PIN_NUMBER='(4)';
PINUSE='UNSPEC';
NO_LOAD_CHECK='Both';
NO_IO_CHECK='Both';
ALLOW_CONNECT='TRUE';
'2':
PIN_NUMBER='(2)';
PINUSE='UNSPEC';
NO_LOAD_CHECK='Both';
NO_IO_CHECK='Both';
ALLOW_CONNECT='TRUE';
'G3':
PIN_NUMBER='(G3)';
PINUSE='POWER';
'G4':
PIN_NUMBER='(G4)';
PINUSE='POWER';
end_pin;

PART_NAME='CONN4_USB_TYPEB_4GNDLOC';
BODY_NAME='CONN4_USB_TYPEB_4GNDLOC';
PHYS_DES_PREFIX='J';
CLASS='IC';
end_body;
end_primitive;

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
