We design and manufacture molds and die assemblies with lots of holes. We use an ordinate scheme to dimension these holes. unfortunately we have holes close to other holes and the leaders don't automatically adjust when they are close so we have to add jogs manually. If we change the hole location the leader needs to be adjusted again. Solidworks does it and our seats of Cadkey from 1992 does it. This would save us gobs of time per year. I have been told that the closest work around is to use the auto ordinate tool. This is a good start but unfortunately it details every possible point on the surface and when you add a hole or move features the ordinate cannot be re-jogged or cleaned up.
Solid Works solves this by allowing the user to select the ordinate and then select a RE-JOG command. Cadkey did it by allowing the user t insert a new ordinate dimension and the scheme would update.
I would propose that when you put down an ordinate scheme you automatically get jogs, and when you modify the design or add an ordinate instance you could go into the CLEAN UP DIMENSIONS command to get them to re-align themselves.
Ordinate with jogs using Auto Ordinate
Ordinate after a design change requires manual re-jogging to get it to place where you can read it.
