How to identify parts using gerber


I'm testing the FAB 3000 with trial period.

I wonder that how it identifies all parts using only gerber files.

I mean, is there a algorithm to recognize whether a shape which is shown by gerber mask layer is part or not?

When I search about FAB 3000, I looked that it exports the centroid file using gerber.

So, I want to know how to export the centroid file about all part.

(such as using part shape database or shaping the solder masks to rectangle, circle etc.)

I hope you can understanding my question. (my English skill is pour...)

Thank you.

Gerber is simply X,Y coordinates with aperture shapes (that's it), there's no intelligence or part details.

You can reverse engineer the gerbers using the paste/mask layers and silkscreen to re-create the components.  Here's a few links showing how to accomplish that task,

If you have an IPC Netlist file, that can be imported and much more efficient.

If you have and ODB++ file or IPC-2581 file (those are intelligent formats), all component information is included and part of those formats.
