Usually, the coordinates in an imported PnP file will have the same origin as the PCB. If not, then the component layer must be aligned with the PCB data, as follows:
- Left-click and draw a rectangle around a component in the component layer. Once selected, a rubber-band stretches from the component to the mouse pointer.
- Left-click and draw a rectangle around all of that component's pads on the PCB.
- The selected component is moved to the center of the selected pads, and all other components are moved the same distance.
Tip: It is often easiest to choose a relatively large hole-mounted component that does not have any vias near the boundaries of the rectangle that encloses the component's pads.
Note: If a component pad (from the originally imported Gerber data) is drawn (as one or more wide lines/arcs) rather than flashed (as a single shape object) then it will not be identified as a pad in the above procedure. In cases where no pads are found within the selection rectangle, the (center of the) selection rectangle is used.
