Hi @JoeChen - The latest revision (6131) has a patch which allows you to specify the location of the DXF origin on the PCB layout editor. So, before you import the DXF, use the cursor to determine the grid coordinates where you want the DXF origin, then do the import, check the option to specify the grid coordinates, and specify the coordinates. Since some people still work in imperial units there is a selection menu to tell the software whether you want to use mm (default) or inches to specify the grid coordinate.
