In principle, all files should have the same coordinate origin in order to insure that all layers match. However, some CAD systems generate different file types with different origins. This can be corrected as follows:
- Click on the Align Pick&Place with Gerbers button to depress the button.
- With the left mouse button, draw a selection rectangle around a pick and place component symbol. A rubber band segment stretches from the symbol to the mouse pointer.
Draw a selection rectangle around the copper pads for the corresponding component. The selected component symbol will move to the center of the bound box surrounding the selected pads. (All other component symbols will also move the same distance.)
Note: Only visible pick and place layers will be moved. If you have pick and place data for both sides of the board, you should show or hide pick and place layers appropriately before aligning them with the Gerber data.
