[Cirilo Bernardo <cirilo.bernardo@xxxxxxxxx>]

I think we discussed this many times and it all came down to "someone
needs to implement it".
If I'm not imagining things the consensus back then was that the units
should be the user's
design units, so if the user had Imperial measures it would remain
0,1-inch but if the user had
Metric measures then it would be mm. To avoid confusion, the GUI would
need to indicate the
units used. There was also some discussion about a Field Validator
which would take units
so people could simply specify the type of unit as they please and it
would magically be
converted to the design units.  However, regardless of what the GUI
does, the files must have
measurements in mm.
