when i move a wall or object the dimension line that is snapped to the wall moves as well.  Does anyone know how to turn off this setting???

That's the associative dimension, you can convert associative dimension to nonassociativeuse with DIMDISASSOCIATE.

In some circumstances,
dimensions are automatically disassociated, including
If the associated geometric object is erased
If the associated geometric object undergoes a Boolean operation such as
UNION or SUBTRACT
If grip editing is used to stretch a dimension parallel to its dimension
line
If the association to a geometric object is specified using the Apparent
Intersection object snap, and the geometric object is moved so that the apparent
intersection no longer exists

you could just manipulate the layer the dim is on....or just delete them and re-dimension...I wouldnt mess with the associative dim setting, its helpful...

[/QUOTE]Agreed! That's why I mentioned the 'Automatic Disassociation' properties.

the dimdisassociate command worked!!! thank you sooo much for responding.  I really really appreciate it..
