Find value then process list?

hey guys i have a question, still learning here... but

my friend sent me this example but has been really busy and we havent had time to talk more. Im not sure how to do it and i could really use it today if i could figure it out, any help would be much appreciated!!

[font=Arial][font=Arial][font=Arial](setq ABC212 (LIST '(AA 1 2 3 4)[/font]
[font=Arial]                            '(AB 2 3 4 5)[/font]
[font=Arial]                            '(AC 3 4 5 6)[/font]
[font=Arial]                    );end list[/font]
[font=Arial]);end setq[/font]
[/font][/font]

What is it you want to achieve?

i want to have a list of parametric shapes that i can draw, then extrude them along a line, im going to use these list to get points then create a pline along the points, then extrude it. So im trying to figure out how to drill into a sub list and load the correct one then plot the points from that sublist, then run the routine

Ok, so what operation do you want to perform on this list?

i want to draw a pline from point to point then close it, then extrude it (by entering a distance)

so i guess enter the defun, then specify the list, like AA then tell it how far to extrude from the basepoint i pick

So the list you provided in your first post is the list of vertices for the polyline?

I would suggest looking into the assoc function.

Don't forget cdr.

Command: (assoc "B" (list '("A" 1 2 3) '("B" 4 5 6) '("C" 7 8 9)))
("B" 4 5 6)
Command: (cdr (assoc "B" (list '("A" 1 2 3) '("B" 4 5 6) '("C" 7 8 9))))
(4 5 6)

let me try that, i just started getting into lisp then i got busy with work now im trying to remember everything
