Get info from all footprints in library

I would like to write a report that gives 3D mapping info for all footprints in the library. I have written a report that works fine for all footprints on a board, so I should be able to simply swap out the list of footprints on the board with a list of footprints in the library. But I'm not sure how to do that.

getDirFiles(axlOSSlash(strcat(axlGetVariable("CDS_SITE") "//footprints"))) gives me a list of all footprints in the library, but I don't know how to access the footprint properties. The board report is as simple as symdef->prop->PKGDEF_STEP_FILE (and the other 3D model properties) for each footprint on the board, but that doesn't work with a pile of PSM files sitting out on a network folder.

Does anyone know how I can access the properties of a footprint on the network? I searched the forum and didn't find anything but I may have just not used the proper search terms. Thanks in advance for any help!
