Convert Gerber to ODB++

Yes, this is possible with FAB 3000 and typically can be achieved in a few minutes.

Here's the 5 steps, and I'll then provide a complete demonstration tutorial movie:

1.  Import Gerber/Drill/Netlist file using AutoLoad (menu: File / Import / AutoLoad...) Assign Layer Types (if not already detected by FAB 3000).

Note:  Typically the netlist already contains the Components information, so XY file are not needed.  If you do wish to import an XY centroid file and use it, here's a dedicated forum post to that task:

2.  Do you wish to have have components? If yes, here's how to generate from Netlist file:

3.  Do you wish to have Nets in the ODB++?  If yes than perform the following to extract netlist from the Gerbers (which do not have any net info):  https://numericalinnovations.freshdesk.com/support/discussions/topics/14000002413 

4. Export ODB++ file. Go to menu:  File / Export / ODB++, and select the location where you wish to save the ODB++.

I am importing a sample set of Gerber files, Drill file, and IPC netlist file.  Performing the steps above, and then export to ODB++.  Lastly I use the Valor ODB++ Viewer for visual verification.
