Lisp Routine to explode nested blocks

[RGilbert77]

Hello All,
I have found several lisp routines that explode all nested blocks within a parent block, but not the other way. I am looking for a lisp routine that will select all blocks in a drawing, determine if it has a nested block inside and then explode. Continue until no nested blocks remain. Forgive the analogy, but imagine an onion where every layer is a nested block. I don't want the outside layer, I want the most internal layer.

Any help would be greatly appreciated.

if you use that lisp and at select object(s) select all option, does it do want you want?

Just to clarify:  You do want the lowest/most-internal Blocks to remain as Blocks?  That is, not themselves also Exploded if they contain no further nested Blocks?

@Kent1Cooper ,

You think what i think?

how about block contain 2 blocks each of them contains 3 blocks each of them contain 4 blocks....

who is going to win?! 😀

You can try EXPLODEALL.

There is an option to keep the last level of block.

It does not.

I tried to be as clear as possible.
But yes...that is exactly what I want.

Is this a standard command?
I just tried it and it's unrecognized.

Not in vanilla AutoCAD, at least.  >Here< is a link to a place where you can get it.
