What's the expectation here? OpenSCAD has no internal
units currently, so this needs to either match the
expectation of the next tools (e.g. for STL which has
no units either) or match the fixed export units that
are set when exporting the file (like for SVG).
The dev snapshot will currently always force export
in mm for SVG. Not sure what the last release version
I printed some drill templates by laying out the holes as small circles in Openscad, exporting as DXF, loading in Inkscape and printing. I didn't have to do anything and the scale came out correct. Then I just taped the printed paper to the object I wanted to drill and used a centre punch to mark all the holes through the paper.
