Comment 11 for bug 1660967

- using the file 1in_sq_Display_inches-Scale_1.svg from comment 7
- using Inkscape 0.92.1 r15371
- save as dxf using the Base Unit mm
- get a dxf file with a rectangle whose sides are .26 mm long, which is much too small

- using trunk Inkscape 0.92+devel 15563
- perform the same sequence using the same Base Unit
- get a dxf file with a rectangle whose sides are 25.4 mm long, as expected

these results are consistent with comment 6 of Bug 1670913
to the best of my knowledge this version of the dxf_outlines.py code has not yet been released, so it would be necessary to get it from trunk in order to test:
