What about 14? It came with LMAN, but if I remember correctly, those VLA-*
calls weren't supported yet.
I may be wrong, I'm a bit fuzzy on those "extended" LISP commands. Once upon
a time they were something,
they changed them to something else.....
While I'm at it, if anyone could clear up the history of those commands, say
with a link, I'd also be grateful.
As Jurgen pointed out, with rel. 14 you can create only one layer
filter. You CAN create layer states that are saved to file, but that is
not what this thread was referring to, or at least that's what I thought
So I'm TOTALLY CONFUSED? Sorry. I thought we were talking about a routine to
delete those nasty named layer states that can only be selected one at a
time for deletion. You were talking about filters applying to the layer
And here is a modified version that asks for the names to delete,
wildcards are allowed.
