error: bad argument type: lentityp nil

[Elektrik]

I do not know how to create lisp codes, but find a lisp code similar to what I had in my mind, but I used ChatGPT to enhance it the way I want it. I provided the lisp script that selects entities of a specified length from the entire drawing. I wanted the following enhancements:

1-Enable multi-selection: Allow the user to make multiple selections before running the script.

2-Filter by layer: Select only the entities that are on the same layer as the selected entities.

3-Match length: For each selected entity, select all entities of the same type and length from the same layer.

 

Now it gives me "bad argument type: lentityp nil lisp" error. Could anyone help me with this lisp? Thanks in advance.

(defun c:sel (/)
 (vl-load-com)
 (setq clear nil)
(setq sel1 (ssget ":S" '((0 . "LWPOLYLINE,line,circle"))))

(repeat (setq i (sslength sel1))
        (setq nam (ssname sel1 (setq i (1- i))))
        (setq ent (entget nam))
        (princ (cdr (assoc 0 ent)))
            (if (= (cdr (assoc 0 ent)) "CIRCLE")
                (setq rad (cdr (assoc 40 ent)))
                (setq len (vla-get-length (vlax-ename->vla-object nam)))
            )
)

(setq selall (ssget "X" (list (assoc 0 ent))))
(repeat (setq i (sslength selall))
            (setq namall (ssname selall (setq i (1- i))))
            (setq entall (entget namall))
                (if (= (cdr (assoc 0 ent)) "CIRCLE")
                    (setq radall (cdr (assoc 40 entall)))
                    (setq lenall (vla-get-length (vlax-ename->vla-object namall)))
                )
                (if (= (cdr (assoc 0 ent)) "CIRCLE")
                    (if (= rad radall) (setq clear (ssadd namall sel1)) (princ))
                    (if (= len lenall) (setq clear (ssadd namall sel1)) (princ))
                )

The lisp code provided by ChatGPT:

bad argument type: lentityp <value>

 

A function requiring an entity argument has been passed an argument of incorrect data type with the value noted in the error message. Usually a result of passing the entget function a null entity argument.

1st answer is that ChatGP is very unreliable so many times code is totally rewritten.

 

2nd "selects entities of a specified length from the entire drawing" length is not a searchable property must get object 1st then can get Length property.

 

You dont say what you want to do with answer so just made a list of lengths.

 

(defun c:wow ( / ss len)

(setq ent (entsel "\nPick a object for layer "))
(setq lay (cdr (assoc 8 (entget (car ent)))))
(setq ss (ssget (list (cons 0 "LWPOLYLINE,line,circle,Arc")(cons 8 Lay))))

(if (= ss nil)
(progn (alert "You have not selected any correct objects \nWill now exit")(exit))
)
(setq lst '())
(repeat (setq x (sslength ss))
  (setq obj (vlax-ename->vla-object (ssname ss (setq x (- x 1)))))
  (setq objname (vlax-get obj 'objectname))

  (cond
   ((= objname "AcDbArc")(setq len (vlax-get obj 'Arclength)))
   ((= objname "AcDbLine")(setq len (vlax-get obj 'length)))
   ((= objname "AcDbCircle")(setq len (vlax-get obj 'Circumference)))
   ((= objname "AcDbPolyline")(setq len (vlax-get obj 'length)))
  )

  (setq lst (cons len lst))
)

(princ)
