Replace one block content with another block at same location

Anonymous — Tue, 17 Apr 2018 16:30:39 GMT

Hi, here is the small description of the help I need..... I have one block (Say block A) which contain a table in it, but the quality of that drawing is not good so now what I am doing is I am creating new Table drawing in another .dwg file & creating new block (Say block B)...... now I want to copy the block B content into block A using block editor...... this I can do it manually.... Also using BLOCKREPLACE the position of block A will change as inside the block editor the drawings are not at the same location................If someone can help me with LISP or VBA script it will be so helpful......

You shouldn't need to resort to code for this simple exercise. If this were something that was needed on a regular basis, then maybe it could be automated.

It sounds like you may be struggling with the relationship of the origin and/or the insertion point and the entities within these blocks. If that is so, post the two blocks and someone will suggest a good workflow for you.

Hi @Anonymous,

Can you share the two drawing files? I am happy to show you in a video how you can redefine the existing block with another one.

I would keep the new version the same name and use a simple block substitution. You can also use Design Center to browse to the new block and redefine the existing.

Hi @vranjanikar,

I made a quick video that shows how to use Design Center to redefine a block using a block with the same name from a different drawing file.

If you want more of a commandline approach that you could script or create an Action Macro, I also show how -Insert, blockname=blockname can do this too.

Hi @Anonymous,

Did the video I produced for you help to understand how the block substitution might work for you?

Use 'Cntrl+2' to open Design Centre, go to the folder where you're new block is. Expand on that until you get to the 'Blocks' folder and you can see the new block. Right click on it an use 'Redefine Only'. After type in ATTSYNC and select the new block. This will synchronise you're attributes with the new block so it all lines up.
