Please help me redefine an Attribute Block

[cscott.94049]

I have a portion of a title block set up as an attribute block. I have made a change to the block (external drawing) and I want to redefine the block in an existing drawing from the updated external drawing.

I used IconTOOL for years until they finally dropped it, and there was a tool that I used that did this automatically. AutoCAD probably has an analog, but I sure as heck cannot find it.

For the life of me I cannot find a lisp routine that will simply redefine a block from an existing external file.

Please help this pathetic CAD monkey.

Cheers,
Chris

I may be way off, but to redefine a block from a drawing use

-insert blockname=drive:/path/blockname.dwg

where blockname is the block name
drive is the drive letter
path is the path to the drawing
and blockname.dwg is the drawing you want to insert to redefine blockname.

It will ask if you want to redefine; say yes. After that, you can cancel before inserting, and the redefinition is still in effect.

You can also do this through ddinsert, just browse to the dwg instead of dropping down the list and selecting the block, and it will ask if you want to redefine.

Or, maybe check out DesignCenter, if you have a recent release.

Hi

See if the following couple of threads offer any assistance...

Attribute block switching routine

How do I to tell AutoCAD to update block?

Have a good one, Mike

I use Design Centre, just use it as a normal explorer window to browse to the drawing that contains the updated blk expand the drawing in the left window secect blocks & on the right will be displayed the blocks contained in the drawing then right click on the title block icon and select redefine block (assumes that the blocks have the same name, use rename if not)

O.K., but how do I change existing instances of the block based on the new definition?

I'd like to update these title blocks without having to re-entering all of the title info.

Thanks a lot for all of the input everybody!

Do it the way Tim said - all instances should update.

[cscott.94049]

Well shoot,

That's exactly what I was hoping you wouldn't say, because it isn't working. I'll continue to play with it and see if I can get it to work.

So, you have two different blocks with the same name?
I hope not because it shouldn't be possible.

BTW, you can start to insert the new block from file, pick an insertion point and then escape from the command.

No... It's a single block with multiple instances. I just modified the external wblock drawing and want to redefine it's instances inside my plan based on the wblock drawing.

I'll try it a few different ways this afternoon and see if I can get a better result. I probably just missed something silly.

Thanks again,
Chris

It will update every instance.

Darn refresh anyway. I missed a couple of posts.

Let me ask:

Is the block you are trying to redefine from contained in another drawing, or is it a drawing itself?
