I have a number of PCB designs created in version 17.2 of OrCAD PCB. Although I have access to PDF fabrication drawings of the PCBs, I need to modify the fabrication drawings, and cannot determine where to find the fabrication drawings. Are they embedded in the PCB (.brd) file? Or should there be a completely separate file for that drawing?



Although drawing information may be created in the board file in this case, it was created externally. 

If the drawing information was generated from Documentation Editor there will be a subdirectory with a name similar to E001CBPCBSMT_C00_XML. The drawing information may also have been exported to a DXF file and generated in a mechanical CAD package.
