What are you dimensioning? Can you post an example SKP file?

Is it possible you aren't clicking an end or mid point or something?

I am trying everything, end points, mid points etc. They sometimes work on the first click and on two occasions have worked on the second. But mostly not. How do I attach the file for you in this forum?

I can't make the Dimensions stick. When I make the second click for a Dimension, it does not stick the second point of the dimension
