Keep all object of certain layers

[ponyrabbit]

I'm a new new new novice

I want to delete all object of dxf "NOT" in certain layers(10, 39, 40)
I've tried many method to do this
(try to close those layer and select all then delete -- failed. Because ssget "x" will select all include hiden layers...)
Final I found some way but still had some problem)

It works as bellow
(setq ss(ssget "x" '((-4 . "<not")(8 . "10")(-4 . "not>")(-4 . "<not")(8 . "39")(-4 . "not>"))))

but fail as bellow
(setq ss(ssget "x" '((-4 . "<not")(8 . "10")(-4 . "not>")(-4 . "<not")(8 . "39")(-4 . "not>")(-4 . "<not")(8 . "40")(-4 . "not>"))))

I don't know why. Please guide me...

Apologize for my bad English....

Hi,

Have a close look at the following:

(ssget "_X" '((-4 . "<NOT") (8 . "10,39,40") (-4 . "NOT>")))

Happy coding.

Still failed....
It works with any combination of any two layers as bellow
(setq ss(ssget "_X" '((-4 . "<NOT") (8 . "10,39") (-4 . "NOT>"))))
(setq ss(ssget "_X" '((-4 . "<NOT") (8 . "10,40") (-4 . "NOT>"))))
(setq ss(ssget "_X" '((-4 . "<NOT") (8 . "39,40") (-4 . "NOT>"))))
.
.

but failed when putting all three layers....
(setq ss(ssget "_X" '((-4 . "<NOT") (8 . "40,10,39") (-4 . "NOT>"))))

Hi,

Are you sure that the name of layers are correct?
Can you upload a copy of the same drawing that you are try the codes on?

I can't upload .dxf file. So I save it as .dwg file

All visible objects into your attached drawing reside on layer name 40 and the codes above is to ignore this layer name along with 10,39 so of course you would have no selection.

I think I find the problem...
All objects are in those three layer (Nothing in other layer) so nothing for delete function...
I should judge the selection before delete it.....

Sorry.....I make such a stupid thing....

No worries, good luck & happy coding.
