No access to dimensions via the Ruby API.

Thanks for the answer.
It is a pity.

I should draw simply in model a dimensional line.

What method Sketchup to construct a dimensional line

ruby script draw square

model = Sketchup.active_model    
entities = model.entities  
pt1 = [0.m,  0.m, 0.m]    
pt2 = [10.m, 0.m, 0.m]

pt3 = [10.m, 10.m, 0.m]
pt4 = [0.m,  10.m, 0.m]
new_face = entities.add_face pt1, pt2, pt3, pt4

How to receive the size of a line Sketchup rubi ?
