Block multiplying and renaming

[rkmcswain]

I have a user that is creating blocks and at some point the block definitions are being duplicated and renamed.

This user says they are not using any 3rd party tools (I thought there might be a add-on doing this...)

For example, user creates a block named 12 FLG-flat-1-flat-1, and at some point later on the user goes into the block list and sees this:

Each one of those is a copy of the original block, but with a different name. 

Any thoughts?

The FLATTEN command from the express tools always does exactly that to blocks.....

I always make sure I do not have blocks selected when attempting that function.

@StephenThomasGrace - Interesting. 

If I answer Yes to "Remove hidden lines?", it explodes the insertions, which is bad for other reasons since the block in question is set to not "allow exploding"

If I answer No to "Remove hidden lines?", the routine fails with this error: "Cannot explode that block.  bad argument type: lselsetp nil"

In neither case did it create additional blocks.

However! If I answer No to "Remove hidden lines?", and the block in question is allowed to be exploded, then BOOM - new extra blocks!

Thanks!

Yes... I had my " What the heck" moment on this a few years back.

I guess that is why, "About Express Tools" says they are provided as a "courtesy" and are "unsupported".

Still, I use it alot for "Flattening" survey linework. Great tool when used carefully.

I use CHZ20 to do flatten work.

To replace all blocks with multiple names, you can try MBLOCKREPLACE with wildcard option.
