change block layer within block.

[darkfprh]

Hi. I need some help for a lisp.

I want to change blocks layer but not all.

please help me...

1. ssget all block.

2. change only block layer, not entity (line, circle, xref etc)

3. not first level block. only inside block.

4. block including block. (= last level's block doesn't change layer)

I don't speak English well.. so I attach example dwg.

I just recently posted a B0.lsp routine that changes all the objects within all block definitions.  I' m sure that with only limited modification it will do what you want.

You can also try CHZ20.

Just input "INSERT1" in "Apply to subentity of".
