The Choose PCB to Use dialogThe Choose PCB to Use dialog


The Choose PCB to Use dialog is used to select which PCB parameters are to be made available in an ActiveBOM when a PCB project includes more than one PCB file.

Visit the ActiveBOM page to learn more.


The dialog is accessed by clicking  in the Sources region on the Columns tab of the ActiveBOM Properties panel.

The dialog is accessed only if the PCB project includes more than one PCB document.


  • PCB Files - this is a list of all PCB files detected in the current PCB project. Select the PCB to use then click OK. The following PCB-specific parameters will be extracted from that PCB and presented in the Columns list, ready to be included in ActiveBOM.
    • Center-X (Mil) - geometric center of the component
    • Center-Y (Mil)
    • Center-X (mm)
    • Center-Y (mm)
    • Layer
    • Pad-X (Mil) - location of Pad 1
    • Pad-Y (Mil)
    • Pad-X (mm)
    • Pad-Y (mm)
    • Ref-X (Mil) - location of component reference point (as defined in the PCB library editor)
    • Ref-Y (Mil)
    • Ref-X (mm)
