Comment 2 for bug 171205

Dimensioning would be helpful indeed for technical sketches.
A nice touch would be to define a multiplier and a dimension
to be drawn (size in drawing is 5mm - this is equivalent to
15m i.e. "scaling").
This is different to CAD programs, where you work on "real
dimensions" and just define the sacling for printing.
Dimensions should include length and angle.
A functionality as in CorelDraw 7.0 is sufficient (adding
the above mentioned scaling function).
