Rado, you asked for chain dimensions and that is what we gave you.
What you are after isn't chain dimensioning at all. %(#0000FF)[For all dimensions you are after use the same
reference point on the left, starting at o(zero), building up to the length overall.]

To do this with Su's dimension tool is tricky. I mean to be able to have them nice looking on screen.
The Text tool might help but for your convenience you then need to position your object with its reference point (zero) at the origin (temporarily though). The Text tool returns X,Y,Z and you still need to adjust the text which will not update when you make changes.
The best option is to apply dimensions only for showing the value in text at the right spots. So just dimension-text that you can alter (alligned to/color/font/height etc.)
