Showing full dimensions in a sketch?

[christopher.leblanc]

  Question, when doing a sketch say making a lathe part.  I draw it out if it was 2inch OD would do 1inch on the line so when I revolve it obviously its a 2inch od.  is there a way in sketching to have it show 2inch on the dimensions from the flat sketch?

If you use a Centerline as the revolve axis in the sketch then When you dimension to the centerline it Will be a Diameter dimension rather than radial

If you look at the models I sent the other day that's How I did them
