Individual Gerber and Drill files are all assigned to individual layers. The Layer Table Detection Template dialog If you don't, you will still have the opportunity to change these settings from their default state each time you import a job. For example, if you regularly receive CAM data generated using P-CAD, you might consider changing the coordinate precision format from 2:3 (Altium Designer defaults) to 4:4 (P-CAD defaults). The CAM Editor - Import/Export page of the Preferences dialog lets you change the default import and export settings for Gerber files. From here, you can alter any of the default extension lists associated with Gerber, Aperture, HPGL, and Netlist files as well. If you receive drill files with different extensions than these, you may extend this list on the CAM Editor - Miscellaneous page of the Preferences dialog. When importing drill files, for instance, the specified directory will filter out all files except those with. The File » Import submenu commands all search for files with certain extensions within a given folder. The IPC netlist will allow you to update the extracted nets with their original names and differentiate between through-hole vias and free non-component pads.

When importing ODB++, only import an IPC file if the netlist is not in the ODB++ directory. If you have an IPC netlist, you should import this as well when importing Gerber and NC Drill data.

The starting point for the whole process is the loading of ODB++, or Gerber and NC Drill files into a new CAM document. The following sections detail steps to be taken to reverse engineer a PCB design from the CAM data, from initial import into a CAM document, through the required pre-export preparation, and ultimately on to export of the design data to the PCB Editor. This does not follow a regular export/import process but rather loads data directly into the PCB Editor. This command allows you to reverse engineer a PCB layout directly from CAM files. After importing CAM data into a CAM document, you will notice that the Export to PCB option is grayed out, regardless of the current CAM Editor mode (CAM or NC).
