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....
