Insert/Replace Block

[ILoveMadoka]

I use CLASSICINSERT, and navigate to my server and pick a block to insert in an existing drawing.

If the block exists I get prompted.

 

"MyBlock" is already defined as a block in this drawing.
Would you like to redefine this block reference?

 

REDEFINE BLOCK?
DON"T REDEFINE BLOCK?

 

So I attempted this:
 

c:foo ()
(command "-insert" "X:\\\MyServer\\AutoCAD Blocks\\MyBlock.dwg")
(princ))

 

This works fine in a drawing where the block does not exist or has not been inserted.

(ie: It does go to the server and insert the block from the correct location)

In a drawing where the block already exists, it merely inserts the pre-existing block again.

 

I have one very specific block that needs to be inserted/replaced/updated in a bunch of drawings

so wanted to create a little snippet to expedite that process in a simple program.

 

I want the program to pull the updated block from the server and insert that and automatically redefine the pre-existing block.

The concept seems easy enough...

 

Help please...

To redefine a block:

 

 

-insert "MyBlock=X:\\\MyServer\\AutoCAD Blocks\\MyBlock.dwg"

Then you'll be prompted to redefine (yes or no?)

and all MyBlock inserts will be refefined then.

 

in LISP, this should work as well

 

 (defun c:redef ( / )
	(command "-insert" "MyBlock=X:\\\MyServer\\AutoCAD Blocks\\MyBlock.dwg")
	(princ)
 )

 

When I do this I further get asked to pick a inseertpoint, scale, rotation...
