How should one properly compile that file then to get the SVG? Using just "mpost something.mp" doesn't work that way. >> (2) I guess that using "raw metapost" is the only sane way to generate >> SVG.

Thanks a lot for the suggestion, I'll test it. It turned out that the (opensource) tools I used for converting SVG into DXF gives very weird result, so I have to change the other parts of the "toolchain" as well. Nevertheless, the question about whether one could convince MP to output true units in cm/mm/in.
