DXF Export with specific Origin

I am exporting a DXF from CATDrawing, to be used in Orcad PCB Design. Is there a way to define the Zero of the dxf? When opening the DXF in Orcad, its about 400x700mm off and this is consistent with each file. I need to constrain the center of a hole, to the zero in the DXF. This way we are not manually moving it in Orcad. Solidworks and NX both allow for the 0,0 to be set in the DXF. I appreciate any help. CAT V5 R19
