Buggy DXF output

I'm trying to use Onshape's support for exporting faces to DXF to do some lasercutting, but getting some really weird results. Certain features - so far, always circles - either appear in the wrong place, or don't appear at all. For an example, see the DXF export of this part - one of the screw holes is entirely missing. I suspect it has something to do with mirrored features, but I can't be certain.

Also, onshape exports to DXF in inches, and doesn't give you the option to change that. Many tools, including my lasercutter, require mm, which adds a tiresome scaling step to the process. It'd be really awesome if you could add support for selecting drawing units (and remembering my choice). Of course, better lasercutter DXF export in general would also be really great.

    Apologies, the missing holes seem to be my fault - not enough constraints, and they got mirrored outside the solid shape, so didn't show up. The issue with in/mm is still a problem, though!

    Nope - the buggy holes are a real thing - here's an example: https://cad.onshape.com/documents/56ded862e4b054e11c27e8ed/w/c82cc85c7f5c666a9f3b931a/e/d4c7e513b05ffaa2afd96655 . The left and right mounting holes both appear on the left when exported to DXF. The part 'Front' is also missing one of the large circular cutouts.

    And, even more confusing, setting the exported version to 2013 doesn't fix the bugs - but it does change the dimension it's exported in from inch to mm!

    Nick - i have spoken to a couple of my drawings colleagues and while we have tested the dxf out (and found the arcs to be in the right place), we would like you to open two support tickets (one for each of these issues - the units and the circles) so that we can dig into this further. Thank you for your support of Onshape.
