Chris,
You need the config option pro_library_dir <path>
Once set, you will see a new folder under the set of Common Folders, with the name of the directory the config option points to. This folder has an icon that looks like a set of books. It uses the .mnu files in each of the sub directories to provide a menu system to guide you to the parts you want.
This can be used in combination with PDMLink, if you already have the files in PDMLink and you ensure that you have the same versions of the files in both locations. I haven't tried it, but I suppose you could point the pro_library_dir to a location within PDMLink.
The syntax of the mnu file is as follows:
eng_part_lib.mnu
PART#LIBRARY <-- Menu name, not important
# but I tend to make it the
# current directory name
/cot_clvs_pin <-- Sub-directory name
Cotter and clevis pin - ANSI B18.8.1-1972(R1977). <-- Description
#
/key
Keys - USAS B17.1-1967.
#
/large_rivet
Large rivets - ANSI B18.1.2-1972.
etc......
The next level down menu file looks like this:
cot_clvs_pin.mnu
PINS
#
#
Pina.prt<-- File name
Cotter pins.<-- Description
#
Pinb.prt
Clevis pins.
#
etc......
