Replace a dimension in the drawing by the variable set in the equation manager

Dear All,

Let's suppose you have a cylinder part. This part has some  configurations where the length and diameter are different.

I set up the length and diameter using two global variables.

Now, I need to show in the drawing not the values of the dimension but the variable set in the equation manager.

I mean, if i put 10, 12 and 14 mm for diameter as values in my configurations ruled by A ,

I need to show in the drawing not 10, 12 or 14, I need to show just A. I  know it is possible to override the and put whatever I want. But, there is a better way? If the part has more than 3  variables could be lousy job

Let me know your comments

Regards

Jose
