Check / create layer issue in Lisp

I wanted to make a routine that:

 

1. checks if a linetype is loaded, if not then it should load it, if yes, then okay

 

2. checks if a layer exists, if not create it (with a specific colour and linetype), if yes, set it current.

 

This is my code:

 

 
(defun c:test ( / ltname layname laycol cmdold) ; functie definitie
(setq ltname "center"  ; defines linetypename
layname "test"   ; defines layername
laycol 8   ; defines layer color
cmdold (getvar "cmdecho")
)     ; end setq
(setvar "cmdecho" 0   ; no following by F2
)     ; end setvar

(if (= (tblsearch "ltype" ltname) nil)
(command "linetype" "l" ltname "acad.lin" "")
)
(if (= (tblsearch "layer" layname))
(command "layer" "s" layname "")
(command "layer" "m" layname "l" ltname "" "c" laycol "" "")
)
(setvar "cmdecho" cmdold); cmdecho back to what it was
(princ); Exit cleanly
); end of defun

 

The problem is when the layer exists, it doesn't set it to current...

 

I'm only 1 inch away from the solution I believe.... but I can't manage to do it.

I have provided a VL option if you wanted to go down that route also:

Lee,

 

It works properly allthough i don't get the code. It's too much to get in to that, so let's leave that part for what it is.

 

This example (test.lsp) is for 1 layer, 1 linetype an 1 colour.

I wonder if it can be made for multiple layers. Not in the way I do it now, thats wrong, defnitly!

 

I copy the code 10 times and change c:test into c:test1 c:test2 etc. Then per function I modifiy the names.

I wouldn't know how to do it else for test1 calls a specific layer.

The code is not that complicated to explain - I could try to answer any questions you may have about it.

 

As for multiple layers, colours etc - Make the layer function into a sub-function, and call it with multiple arguments:

 

(defun mklay (layname laycol ltname / lay)
 (vl-load-com)

 ;; Loading Linetype  ~ Another option to consider:

 (if (not (tblsearch "LTYPE" ltname))
   (vla-load
     (vla-get-Linetypes
       (vla-get-ActiveDocument
         (vlax-get-acad-object))) ltname "acad.lin"))

 ;; Another Option for Layer Creation to Consider:

 (if (not (tblsearch "LAYER" layname))
   (progn
     (setq lay (vla-add
                 (vla-get-layers
                   (vla-get-ActiveDocument
                     (vlax-get-acad-object))) layname))
     (vla-put-color lay laycol)
     (vla-put-linetype lay ltname)))
 (setvar "CLAYER" layname))



(defun c:test ()
 (mapcar 'mklay
         '("test1" "test2" "test3")
         '(8 3 4)
         '("CENTER" "HIDDEN" "CONTINUOUS"))
 (princ))

 

This will make three layers:

 

test1 -- colour 8 -- CENTER

test2 -- colour 3 -- HIDDEN

test3 -- colour 4 -- CONTINUOUS

 

Hope this helps,

 

Lee

Here is a Linetype loading sub that I use all the time, along with a helper sub.

 

Just pass it a linetype name and it will search every .lin files in your search path and if it finds it, it gets loaded.

 

The only thing that I want to do to it, is if a path is supplied than it loads the linetype directly.

STDLIB_LOAD_LINETYPE.lsp

Heres one that I use it purges all unused layers then create the 10 layers I use. You can modify the layer names to your liking and at the end of the dolayers command you can modify to set layer current.

 

(setvar "clayer" "insert layer name here")

 

I know its rokkie programing but it works for me. I use it to make sure all our drawing have the same layers since I'm the 4th draftsman here we have a lot of different drawings.

 

Oh and thanks Lee Mac I saw something like this in one of his commands so I just made some mod's to it.

 

 
(defun createlayer (NAME)
(if
 (not (tblsearch "LAYER" NAME))
 (command "-layer" "m" "CEN" "C" "6" "CEN" "L" "CENTER" "CEN" "LW" "0.18" "CEN" "")
)

)
(if

 (command "-layer" "m" "TXT" "C" "7" "" "")
)
)

(defun c:dolayers ()
(setvar "cmdecho" 0)
(purgelayers)

Bradb,

 

the way you have called the sub-function, each statement is independent of the argument supplied. I.e. Every IF statement will return T for every single layer that doesnt exist.

Ah is that because I purged all layers away prior to create layer. I originally wanted it to search for layers then rename them. Ex. search for OBJECT and OBJ. And OBJECT rename to OBJ. And if OBJ then nothing will happen, But if neither exist then create OBJ.

No, it is because you are supplying every IF statement with the same argument.

 

This is much better (and much faster):

I'm not sure what your "purgelayers" function does, but maybe I could improve that also :)

This is the purgelayers did realize I didn't copy it before. Basicly I want to purge all layers that are not the layer names supplied in the lisp

Lee, this is the solution in my case.

 

I want to create a specific layer when inserting specific blocks, ie. inserting a block called "box" in a layer "boxes", linetype center, layer set to non plot, I use a macro inside menu:

 

^C^Ccreatelayer;Center;m_boxes;3;n;

 

This is the lisp that starts up when a drawing is opened:

 

 
(defun c:createlayer (/ ltname layname laycol cmdold lay)
 (vl-load-com)
 (setq ltname (getstring "\nPlease enter the name of the linetype: ")
       layname (getstring "\nPlease enter the name of the layer: ")
       laycol (getint "\nPlease enter the colour of the layer: ")
layplot (getstring "\nDo you want the layer to be <Plot> or <Non plot>: ")
       cmdold (getvar "CMDECHO"))
 (setvar "CMDECHO" 0)
 ;; Loading Linetype  ~ Another option to consider:
 (if (not (tblsearch "LTYPE" ltname))
   (vla-load
     (vla-get-Linetypes
       (vla-get-ActiveDocument
         (vlax-get-acad-object))) ltname "acad.lin"))
 ;; Layer Checking & Creation
 (if (not (tblsearch "LAYER" layname))
   (command "_.-layer" "_M" layname "_L" ltname layname "_C" laycol layname "_P" layplot "" "")
   (setvar "CLAYER" layname))
 ;; Another Option for Layer Creation to Consider:
 (if (not (tblsearch "LAYER" layname))
   (progn
     (setq lay (vla-add
                 (vla-get-layers
                   (vla-get-ActiveDocument
                     (vlax-get-acad-object))) layname))
     (vla-put-color lay laycol)
     (vla-put-linetype lay ltname)))
 (setvar "CLAYER" layname)
 ;; Reset CMDECHO
 (setvar "CMDECHO" cmdold)
 (princ))

 

So now I specify the layer in a macro, that gives me much flexibility for whenever there is a new kind of block to insert, I createlayer...

 

But all credits to yuo lee, without your help I wouldn't be able to do so.

They are Visual LISP methods - AfraLISP has a lot of information on them :)

Thanks Marco,

 

But bear in mind that with your code, you have got two sections that do the same thing. - You might want to consider removing one.
