LAYDEL from a LISP
I am trying to duplicate the functionality of LAYDEL from inside a LISP. ie I need to delete a layer that has entities on it, and entities inside block definitions. They have redone LAYDEL for v26 so at least it works from the command line, if in a very clunky fashion. But I can't get it to work from inside a LISP using any of the command-s type things, because the number of questions is variable depending on whether there are entities inside blocks or not. I'd rather not have to write a LISP that goes through all the block definitions, but if I have to … Anybody got a better solution ?

1 You can select an object to get layer name.
2 You can select all objects on that layer and erase.
3 Could test does block have sub blocks, I think that is what your asking. Please confirm
4 There is get nested block names from a block lisp, you need to get that defun.

Hello.
In my testing with V26, using an sequence like:
(setq ent_n (car (entsel)))
(command "_laydel" ent_n "" "_y")
(graphscr)worked fine.
If the case is more complex, something useful could be to use the CMDACTIVE sysvar to check whether the command (LAYDEL) is still active.

The reason you can't control LAYDEL from LISP is that it is also a LISP function.
: !C:LAYDEL
#<<FUNCTION> #x38 @1000326af6>I would try putting in a support request to ask for the routine to be updated to honour the EXPERT sysvar setting i.e. EXPERT = 5 deletes requested layer without additional confirmation prompting.

Thanks for the various suggestions.
Yes, I have blocks within blocks that have entities on the layer I want to delete.
Have opted for the simplest solution - I've given up with this 🤣

you can roll a lisp function with Python.
Example AutoLISP execution usage: (pylaydel '("1_1_WALLS" "1_CRP_WALLS"))0
