Dia dims in profile view

Hello;

       This part I constucted was created with dia dims using the center line. Does anyone know how I could show dia dims

straddleing the center in in the drawing view? I've attached the files. I can do it by creating a construction line as I've shown, but

I was wondering if there's anyway to do that automatically, without the construction line similar to sketchs with a center line.

Thks in advance for any input
