I should have mentioned that I am using AM 2005, and I am trying to change a user counterbore.
When I 2x click the c-bore, there is no drop down menu. I can change to diameter, depth, nominal diameter, and location, but that's it.
I suppose I should have changed the values of an ANSI counterbore and then I might not have this problem.
Of course, if I drew it right to start with, I wouldn't have had the problem to start with.
