If all the primitives (TEXT,MTEXT,INSERT,LINE,LWP,Circle,Mleader,Dimension) are perceived as objects, then you can use this code: ;; Set coordinates of objects (TEXT,MTEXT,INSERT,LINE,LWP,Circle,Mleader,Dimension) Z in 0 (defun zeroz-in-list (lst /) (cond ;; The list of coordinates-vertex ((and (listp lst) (= (length lst) 2) (numberp (car lst)) (numberp (cadr lst))) ;; if only XY - expanding to XYZ (list (car lst) (cadr lst) 0.0) ) ((and (listp lst) (= (length lst) 3) (numberp (car lst)) (numberp (cadr lst)) (numberp (caddr lst))) ;; if already XYZ - just do Z=0.0 (list (car lst) (cadr lst) 0.0) ) ;; If it's a large list, it's probably nested ((listp lst) (mapcar 'zeroz-in-list lst) ) (t lst) ) ) (defun c:ObjZ0 (/ ss n e el newel) (prompt " Select objects (all types, including polylines, mleader, dimension): ") (if (setq ss (ssget)) (progn (setq n 0) (while (< n (sslength ss)) (setq e (ssname ss n) el (entget e) newel nil ) (foreach pair el (cond ;; height LWPOLYLINE (code 38) ((and (= (car pair) 38) (numberp (cdr pair))) (setq newel (cons (cons 38 0.0) newel)) ) ;;Point codes (for example, 10, 11, 12...), etc. ((and (numberp (car pair)) (not (= (car pair) 210))) ; Don't touch the normal (if (listp (cdr pair)) (setq newel (cons (cons (car pair) (zeroz-in-list (cdr pair))) newel)) (setq newel (cons pair newel)) ) ) ;; The rest (t (setq newel (cons pair newel))) ) ) ;; Restoring order and modifying the object (entmod (reverse newel)) (setq n (1+ n)) ) ) ) (princ) ) If the Z coordinate is not displayed in the properties (example, for dimensions, for Mleader), then you need to use the _LIST command. Don't think of me as a programmer... The code is written using AI.

There was a thread a few days ago about speeding up a LISP to do the same, have look at that for ideas. I think the thread got as far as arcs are tricky to do with LISPs. You could use the flatten command for small drawings. This snippet will filter a selection set to lines or LWPolylines to anything not 0 Z (setq MySS (ssget (list (cons 0 "*TEXT,INSERT,LINE,LWPOLYLINE") '(-4 . "<OR") '(-4 . "*,*,<>") (list 10 0.0 0.0 0.0) '(-4 . "*,*,<>") (list 11 0.0 0.0 0.0) '(-4 . "<>") (cons 38 0) '(-4 . "OR>") )) ; end list, end ssget ) Can be added to the other solutions herein the case that your drawing has a lot of lines / polylines / blocks it speeds it up a bit Link to other thread:

Hi @p7q, You can try with this several options from image below. From the last lines of code, you will get something like this. Try to play with this. Also, you can get from Lee Mac website about Attribute Functions. Best regards.
