Lisp to replace block with another block

[Manicbala]

Hi,

I have tried the below lisp to replace the block "RR" with "Level".

(defun C:QW4 ()

((C:-BLOCKREPLACE) "RR" "level" ""))

{{ Command: QW4
Initializing...
Select the block to be replaced or [?/= (select object)]: }}

After enter QW4 command, its prompting to select the block instead of replacing. Please resolve this.

So it appears that running INSERT and selecting the block from the folder it's saved in will prompt for "Redefine Block" but running -INSERT from the command line or LISP does not. Even though the block .dwg has been updated with a new definition and I'm specifically calling up that file location in the command line/LISP, AutoCAD is still inserting the old definition without asking if I'd like to replace the existing definition. I even tried copying the .dwg with the new block definition to a different file location and calling that up, but got the same result.

UPDATE: I figured it out. I realized what you were hinting at is that it needs to be formatted as:

(command "-insert" "BLOCKNAME=filelocation/BLOCKNAME.dwg" ...)

Thanks.

Had a similar issue with replacing a block.  This piece of code helped me greatly.
