Anyone know if there's a way to export Altium PCB part outlines (I don't care about the detailed view of a part, just its physical 2D circle or polygon envelope) to an easy-to-parse output file?

I need to draw some annotations + would like to handle them programmatically rather than manually, using some data processing scripts I am writing. I need to get coordinate data of a few dozen parts automatically, so it's not practical for me to get the coordinate data manually, since it would take me several hours, and I would have to redo it during layout changes.
