LISP to select lines and text according to "Z" values

[shokoufeh]

Hi everyone

I am looking for a lisp to quick select different objects according to their specific properties in the entire drawing. The objects I am going to select are:

1- Every line that has "start Z" or "End Z" "Not Equal" to zero.

2- All "Text" that have "Position Z"  "Not Equal" to zero.

3- All "Block References" that have "Position Z"  "Not Equal" to zero.

4- All "Polyline"  that have "Elevation"  "Not Equal" to zero.

 

Actually, I have so many files in which, Z values are not zero (Z values are about for example 0.000001). It makes the file so difficult to edit. I want to select every object and manually change the Z values to "zero". 

 

Also, it would be great if you guys can help me by any other way, to solve my problem and change the whole drawing's Z value to "zero", if possible. 

If not, it doesn't matter. Help me to write this Lisp, so that the selection of the objects get easier. 

Below, I attach a simple sample of my file, in which, some block, text, or lines have Z value other than zero.

thank you.

It seems that this lisp finds the lines with Z value problem and adds a label near them. It is great that it can find the lines, but I don't want this label to be added near this lines. I only need to select them.

Can this lisp file be modified, so that it changes the Z values of the selected lines, to Zero?
I mean, it selects the lines and modifies the "Start Z" and "End Z" to 0.

Try

(defun c:todoA0 (/ cj e le n to p1 p2)
  (IF (setq cj (ssget "x" '((0 . "TEXT,MTEXT,INSERT,LINE,LWP*"))))
    (while (setq e (ssname cj (setq n (if n (1+ n) 0))))
      (setq le (entget e)
	    to (cdr (assoc 0 le))
	    p1 (assoc 10 le)
      )
      (cond
	((= to "LINE")
	 (setq p2 (assoc 11 le))
	 (entmod (subst (cons 10 (list (cadr p1) (caddr p1) 0.0)) p1 le))
	 (entmod (subst (cons 11 (list (cadr p2) (caddr p2) 0.0)) p2 le))
        )
	((= to "LWPOLYLINE")
	 (entmod (subst (cons 38 0.0) (assoc 38 le) le))
        )
	((member to '("TEXT" "MTEXT" "INSERT"))
	 (entmod (subst (cons 10 (list (cadr p1) (caddr p1) 0.0)) p1 le))
	)
      )

Wow

It worked great.

thank you very much.

just one last question: Only "End Z" of lines are being modified to Zero. how can I make this modification to "Start Z" of lines, too?

Please check this code. I made a few modification, and I think now it works for both start and end Z values.

GREAT. It works.

Sounds good
If you've tried it and it works:

[Steven P]

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

I was checking my files and I found out another problem. Except elements I mentioned (lines, poly lines, texts and blocks), the problem with Z values exist in other elements, as I mention below:

 

Hatch: Elevation

Leader: Vertex Z

Ellipse: Start Z, Center Z, End Z 

Arc: Start Z, Center Z, End Z

Circle: Center Z

Solid: Elevation

Attribute Definition: Text Alignment Z

Array (Rectangular) : Base Z

 

Please check this modified lisp and see if it is correct or not. This lisp doesn't work on HATCH.

ZRemove.lsp

I think hatch is the first '10' if an elevation has been set (10 0.0 0.0 'Z')

Missed your message but am intrigued now... (a guess I would say you were saying LWPolyline has X, Y, Z coords - I've done the same many times too)

Yes
I briefly forgot that LWPOLYLINES don't have a Z coordinate and instead use group 38 to define their elevation.

Therefore @shokoufeh: the code you added to set the Z for LWPOLYLINES is unnecessary

Use what you have done previously but for dx code 10:

 

          (foreach dxf le
            (if (= (car dxf) 10)
              (setq le (subst (cons 10 (zeroz (cdr dxf))) dxf le))
            )
          )
