current layer change

Hello everyone,

Here's my problem: I'm building a lisp routine that inserts a block along a line and I want the block to be placed on the layer that the line is on +1 (The route I'm taking is just to change the current layer before insertion instead of changing the block attribute. If it's easier for you to do it the other way that's fine. Also, all layers are numerical). For example, if the line is on layer 2, I want the block to be placed automatically on layer 3. Below is my failed attempt. Can anyone help? Thank you.

(setq linelayer(assoc 8 ent2))

(setq blocklayer (+ (atoi linelayer) 1)

(setq blocklayer (itoa blocklayer))

(setvar "clayer" blocklayer)

left off a 'cdr'

(setq linelayer (cdr (assoc 8 ent2)))

Thank you sir for responding. still no luck though. comes back with:

error: AutoCAD variable setting rejected: "clayer"

(8 . "2")

fyi the line is on layer 2

oops found the other problem.

needed another ")" at the end of line 2. Thanks again!

From error it doesn't seem like you fixed the right line. The following should work, if 'ent2' is the line "entget" list.

(setq linelayer (cdr (assoc 8 ent2)))

(setq blocklayer (+ (atoi linelayer) 1)

(setq blocklayer (itoa blocklayer))

(setvar "clayer" blocklayer)

-----edit------

oops, OK, glad you got it.
