RH AutoDimension 01//////////////////////////////////////////

This Rhinoscript evaluates lenght of curves or lines and creates dimension using the rhino command "Dimension". The code needs improvements like external or internal dimension differentation and much more. I used this script on many panels unrolled from a parametric installation, in a few time I had all the panels dimensioned.
