Topic: Help: How to go through layer list?

[HasanCAD]

This lisp to create a line with layer color and ltype and text with layer name
But do not know how to go through the layer table.

Code: [Select]

(defun c:Layers ()
  (vl-load-com)

  (setq AcObj (vlax-get-Acad-Object))
  (setq ActDoc (vla-get-ActiveDocument AcObj))
  (vla-EndUndoMark ActDoc)
  (vla-StartUndoMark ActDoc)

  (setq Cntr -1)
  (setq Pnt0 (trans (getpoint "\nBase point")1 0))

 
  (while
    (setq LayerLst0 (tblsearch "LAYER"))
    (setq LayerLst1 (ssname LayerLst0 (setq Cntr (1+ Cntr))))
    (setq LayerLst2 (entget LayerLst1))
    (if
      (and
  (setq Pnt1 (list (+ (car pnt0) 500) (cadr pnt0) (caddr pnt0)))
  (setq Pnt2 (list (+ (car pnt0) 600) (cadr pnt0) (caddr pnt0)))
  )
    (progn
      (entmakex (list
  (cons 0 "LINE")
                  (cons 10 Pnt0)
                  (cons 11 Pnt1)
  ))
      (entmakex (list
  (cons 0 "TEXT")
                  (cons 10  Pnt2)
                  (cons 40 110)
                  (cons 1  (getvar "CLayer"))
  ))
      (setq Pnt0 (list (car pnt0) (+ (car pnt0) 150) (caddr pnt0)))
      )
    )

  (vla-EndUndoMark ActDoc)
  )
(princ "\n Type c:Layers to start ")
  )

I tried to make text alignment but create all test in 0,0

Code: [Select]

(entmakex (list
      (cons 0  "TEXT")
      (cons 1  LyrName)

Very Cool!. 
I would suggest two improvements.  One draw the line and text in alphabetical order and two draw their lines with their correct line type settings.

Otherwise two comments, very cool.

First Thanks for your encouragement and comments
for first one I Want to do this, but dont know How 
for second I am using the layer line type. Is it correct? or what?

Write out in plain words what your current program is doing (this is called: "Pseudo Code"). After you do that we can talk.

I am answing MedOffBud improvements
For first improvement I want to arrange in alphabetical order but I dont know how.
For second improvement I didn't understand what he said, so I told him what I did.

Is it OK

Sorry for the confusion on the second part. Your code is drawing a line on certain layer right?  I was wondering why line was drawn as continuous when a layer (like a center line) should be drawn also with center line line type?  

What Se7en "is trying to say" [before he hurts himself ] is write out your code descriptively (Just words no code) on a piece of paper.  I do mine with the classic "Step 1:  blah blah blah"  "Step 2:  blah blah blah"  and so on.

Is that a little clearer?

[JohnK]

Sorry, but there goes the chance for help from me; not because of a misunderstanding but because of lack of trying to understand (Frankly, I didnt try to say anything, i said it. I said PSEUDO CODE and if that wasnt clear, then a google search would have helped).
