Export DXF for Laser Cutting

GWS50GWS50 Member Posts: 204 PRO
I'm trying to export a part for laser cutting but the exported file is in inches and so is much bigger than it should be. (I'm working in mm)
Is there a setting that I'm missing?

    P.S. This wasn't happening when I last did this about a month ago

    When the part is exported as a 3d file i.e. Step or STL the dimensions are correct

    I think this is a bug. When I change the workspace units to inches the exported DXF behaves correctly

    So it seems it depends on the company you're sending the DXFs to as to whether they scale correctly. I have used quite a few different cutters over the years and it is only now that this has been an issue. Many thanks for the help

    Yeah I use Waterjet and lasercut companies for several years. The issue is usually on their end. 

    One time around 2005 or so a colleague had designed a custom screw or pin, I forgot exactly what. It was supposed to be about 1 or 2 inches long, and 1/4” or so in diameter. When he got the parts back, they were bigger than his hand. We all had a good laugh. This was from a CNC vendor I believe.
