Comparing PCB Layout Viewables to Gerber Overlays
Compare a PCB Layout viewable to a Gerber overlay. In the Quick Results view, you can perform these operations:
Align the viewables
Control visibility of the overlay, the PCB sublayers, or both
Set options
Search
* 
Because the overlay is not searchable, the results come only from the PCB Layout.
In a Quick Results view only, on the Compare ribbon, use these strategies to align the viewables:
Align—Select a point on each viewable to align. For more information, see To Align an Overlay by Aligning Vertices.
Rotate Left, Rotate Right, Flip Vertically, and Flip Horizontally—Turn and mirror the overlay to match the PCB Layout. For more information, see To Align an Overlay by Rotating or Flipping.
Overlay Options—Set options such as offsets, scale, and rotation. For Gerber overlays, see To Set the Format, Scale, and Position Options for Gerber RS-274D Files.
