LISP to move selected objects to a specified layer?

[Dan Kitchens]

Hi peoples,

 

I've got a new challenge: Is there a Lisp that moves selected objects to an exisitng, specified layer?

 

I want to be able to select objects on the screen, type in a short command, and they automatically go to a certain layer (let's call it "Layer 1").

 

Having looked everywhere on the net, I can't find anything similar, and I don't know enough AutoLISP to be able to write it myself...

 

Thank you in advance!

 

Dan

There are lisp-free ways to do it within the program, you can use COPYTOLAYER. If you are sure you want to use lisp, then it looks like you may find your answer in the similar threads section at the bottom of this page.

Hi Dadgad,

 

Thanks for your suggestions.

 

COPYTOLAYER won't work because I don't want to copy the objects, I want to move them to a specified layer.

As for the below threads, I've just taken another look, and I can't find anything.

 

Surely there is a Lisp out there somewhere.

CHANGE command or PROPERTIES. Or you could write a script or action recorder macro.

Have you checked on Lee Mac's website, I bet he has something that will do that.

LAYMCH maybe?

[Dadgad]

That's the ticket, never used that one, good call! I would do it in my quick properties palette, which is always open.

Thanks all for your input. The LAYMCH does work, but I find it too slow. My prop. palette is always closed so I can maximise working space, and it takes too long to open to be of any use.

 

The good news is that I found a Lisp at another site:

 

http://www.theswamp.org/index.php?topic=33195.0

 

The code reads: -

 

; Changes selected objects to Layer PL1
(defun c:setpl1 ()
 (command "_.chprop"
   (ssget ) "" "LA" "PL1" "")
        )

 

 

Thanks to memerson for that one. And thank you all for your help.

Let's use CODE TAGS next time!!!!!!

Glad you got it sorted, I hate the Properties palette, I find it to be a total nightmare. I love the QUICK PROPERTIES palette which is customizable and can be as small as you want it, and gets you all the info you need, on the fly, no waiting.

Version without use of commands (works more quickly). If the layer with such name does not exist, it is created

; Changes selected objects to Layer PL1
(defun c:setpl1 ()
 (tolayer
   (ssget "_:L") ;;selection
   "PL1"         ;;Layer
   )
 (princ)
)
(defun tolayer ( ss lay / i e )
 ;;; ss - pickset
 ;;; lay -layer name
 (repeat (setq i (sslength ss))
   (entmod
     (subst
       (cons 8 lay)
       (assoc 8 (entget (setq e (ssname ss (setq i (1- i))))))
       (entget e)
       )
     )
   )
 )

Why not just select your objects, select the Layer Drop-down and choose the layer; the objects will be moved to the layer you select:

Lee Mac it always does my heart good to see one as gifted at programming as you offer a native solution. As one who is not lisp-savvy, and would love to be, I never cease to be amazed by the depth of automation to which some folks aspire. More power to them. My attitude is, if it works, don't fix it.

Thank you Dadgad

 

I agree that many requests on this forum are attempting to reinvent existing AutoCAD functionality, but I suppose it also depends on how often the user is changing objects to a particular layer and how many layers exist in the drawing. Perhaps the OP is changing the same objects to a particular layer many times over in a drawing that contains hundreds of layers... at that point, I would also look to automate the procedure.

 

Well, at least he/she has many options now.
