Dimensions explode on application?

Hey everybody!

I was wondering if anyone knows what the setting is and how to reverse it or change it when you dimensions explode apon application?

I work with 2 other drafties and neither one of them know. I am backdrafting a drawing in Autocad 2009 and everytime i put in a dimension it asks me to enter text to edit or enter, i press enter and it has exploded so that the triangle, leaders and extension lines are all seperate.

I checked out the dimension properties and nothing appears to be any different to the norm...

Anyone got a clue?

ok, so if I type in "dimassoc" it comes up 0, so I typed in 1 and that makes all the dim lines associate from this point on. which is great! at least i have worked out that much.

anyone know how to make the existing lines re-associate?

Sorry there's no way to reassociate DIMS that have been set from DIMASSOC variable 0.

You'll need to redo them a real bummer.

but anybody correct me if im wrong

oh well worth a try!

Thanks for your help!
