Thanks for fast reaction.
In the illustration , the used command (CBI ) doesn't work.
And command (base) has nothing to do with block base point.
Any other suggestion?
You typed CBI at the command prompt to run the portion that didn't work. Now type CBIR at the command to try the second option of the lisp program.
If you don't want to use this program then create a new block in a separate drawing of your block with the same name. Define the base point as you desire and then open the base file and insert the new block. It will ask you if you want to redefine the old block. Keep in mind that the block will probably shift in your base because of the different insertion point.
