dimension problems autocad 2008

Why are my dimension lines stretching when I move an object? It
appears that there are points attached to the dimension that will not
move with the rest of the drawing and they end up stretching all the
way to the new location. This only happens when I try to move but does
not happen when I copy. I've never seen this happen before in earlier
autocad versions I need a solution asap...... I'm praying there is a
simple setting or variable. Thanks in advance,

Your dimensional lines are stretching likely because they are
"attached" to the object you are moving. You can turn this on and off
as you wish. The help section of AutoCAD should be really good at
describing how to do that (now that you know that that is the
problem). There is also a command that lets you redefine what a
dimension is attached to (I think, but am not positive, that it is
"attre" or "attredefine"; I do not have AutoCAD on this cocmputer, so
I can not know for sure - it's been a whilse since I've used AutoCAD).
Dimensions can be either attached or unattached, and it sounds like
you want unattached dimensions.

 

Unfortunately, I don't think that's it. I suspect it's a bug because
I've had this problem from time to time but find it hard to replicate
now regardless of what dimaso/dimassoc setting I've got set. I suggest
you just make sure that associative dimensioning setting in your
version of AutoCAD are set correctly (for you), and redraw those
wayward dimensions - making sure to attach both ends of the dimension
to objects. (But I've been lucky. This workaround has only ever
involved the redrawing of a handful of dimensions.)

 

I know what you are talking about. But I don't know the fix.

I use ACAD LT 2008.

Sometimes I will move an entire batch of lines, etc. with dimensions for
them. Everything that the dimensions could possibly be tied to is moved.

But parts of some dimensions will sometimes get stuck in the old location,
making that particular dimension only good for deletion. Seems like a bug.

I haven't looked into it particularly as to why.

I've seen this before, and I think it's because at least part of the
dimension has been associated to an actual in the drawing plane in
AutoCAD. I could be wrong, though. Try selecting all (ctrl-A), typing
dre (dimreassociate, dre launches it for me, but that may be something
I customized... just launch the dimension re-associate command), then
holding down the enter key. It's been a while, but that may fix the
problem. Either that, or select all, then in the properties window,
select the various items, in turn, that are dimensions (ie: linear
dimensions, etc..), then change the properties of the entire group to
"UnAssociated". That should clear the problem right up. If this is
still not working, then you may need to write your own VBA-Sub to
select all dimensions, and set them all to be "Unassociated". If you
are feeling really adventurous, try writing a sub that lets you select
some objects, then pauses execution, then you can examine that object
in the Watch Window; compare a dimension that moves properly to one
that you know will not move properly (an example of a dimension that
will not move proerly can be obtained when next you have this problem;
just choose "undo" until before the move. Then move it again jsut to
make sure the probelm still exists (if the problem goes away once you
undo the move, then make the move again, then problem solved ). If
the problem still exists, undo to before the move, then examine, in
VBA, the properties of the afflicted dimension and compare them to a
properly working dimension. If you can discern the difference, you can
probably set that property directly using a VBA-Sub. Just write
something that will select all objects that are dimensions, and then
change that property in all of them. Or, find someone who knows what
the hades all that gibberish means and ask them to do it. I could do
it myself if you cared to email me an example of this problem occuring
(a .dwg where the problem occurs - if I have an example, I can do much
much more). I ahve AutoCAD 2005 at home, and I think AutoCAD 2007...
or maybe 2006... just don't ask where I got it >
