How to change an attribute name?

[Anonymous]

I have two blocks. I used to use one of them before, but now i made changes to the old one. Now i want to change all the drawings that i have with the old block.

I used "Redefine Only" on the Desing Center and then all blocks changed but still have the old attributes with the new form. Now when i try to change the attribute name to the new one using "Manage Attribute", i only see the new attribute on the list, but the blocks changed have the old attribute.

Is there any way for changing the name of the old attribute to the new name? I need it because i'll make an extraction to excel and they are too many blocks changed.

Thank's

These are the three blocks

After you redefine the block in the older drawings you need to sync the old inserted blocks with the updated attributes in the block definition.   Run 'ATTSYNC' and follow the prompts.

It alredy worked, but all the attributes moved to their original states, so I have to organize them one by one.
