Have one doubt.....
in one drawing i have many same named blocks....but i have to edit in only one blocked object... but i not want to "X" that object....if i "X" that object i have to rebuilt all....when am editing that single block other blocks properties not have to change.....
Can any one resolve this please...

Copy block
to new drawing, use block editor and save this block as new one _BSAVEAS

Do all
changes you need under new block and you do not need to explode original one

Easier solution:Select the block you want to change.Explode it.Make your changes.Select all of it again and redefine it with a new block name.  Be sure to Retain the linework in the drawing when you create the new block so you don't lose the position.Dave.

Try the use of BLOCKREPLACE ( and ATTSYNC for the blocks with attributes ).

Best method I've used:1) Enter the Block Editor.2) Do all your changes you want to do.3) Save the changes.After you come back to the original drawing, 4) Use  command: BATTMANSelect your block from the upper drop-down menu5) Press the "Sync" button.6) Click the OK button.optional: 7) Use command: REA (to regen all)8) Good luck
