    Any way of scaling an NC drill file

    This is not milling related but drilling.

    My circuit board is fractionally undersized. I'm guessing my printer which made my photo positive does not have super dimensional accuracy.

    Therefore I need to rescale my NC drill file very slightly to match the actual board size (hole centre distances). Unfortunately my cam software is not working in this respect and no matter how I attempt to change the scale on import, the hole to hole distances stay the same.

    My PCB software (Diptrace) does not have any scaling for exporting the drill file.

    Therefore I'm on the hunt for any way I can change the scale of my PCB drill file on export, or any software which can import and NC drill file, re-scale it, then export it again.

    Any ideas,

    Keith.

    It's OK, figured it out. Export DXF from Diptrace then scaled in cad software. Got all hole locations perfect now.
