LISP for assigning layer color

February 18, 2008

Hi all,

I'm using Map 3D to import a large number of .shp files to set up my base file. The issue I have is all the objects come in with a layer color of "white". It's really hard to have any idea what layer an object is on by looking at the drawing.

My thought was a LISP that would assign a color to each layer perhaps just the first six colors. It would end up looking something like the following...

BLDG_1695_1160C -- Color 1

Default_BASEBALL -- Color 2

Default_BASEBALL_FUTURE -- Color 3

Default_BLDG_1695_1155A -- Color 4

Default_BLDG_1695_1155B -- Color 5

Default_BLDG_1695_1160B -- Color 6

Default_BLDG_1695_1160C -- Color 1

Default_BOUNDARY -- Color 2

Default_CENTERROW -- Color 3

Default_CONINDEXDES -- Color 4

Default_CONINTERDES -- Color 5

Default_CONTEXTDES -- Color 6

Default_ESMT -- Color 1

Default_EXEDGPVMT -- Color 2

Is there a LISP that will assign a different color to the layers?

Thanks in advance

Do you want a random color or a predetermined color?

The following will assign a different color (in order from 1-255) to each layer. If you want a random color, there is a random number generator in lisp here. If you want a specific color per layer, then you will have to set up some sort of mapping list so it will know what color to use for each layer.

(vl-load-com)
(defun C:Lcolor ( / c x)
 (setq c 1)
 (vlax-for
   x
   (vla-get-Layers (vla-get-ActiveDocument (vlax-get-acad-object)))
   (vla-put-Color x c)
   (if (eq c 255)
     (setq c 1)
     (setq c (1+ c))
   )
 )
)

Try this. All layers in the list must be unlocked and unfrozen.

(defun c:layd(/ Lst curLay fLst laySet)
 
 (setq Lst (list
'("BLDG_1695_1160C" 1)
'("Default_BASEBALL" 2)
'("Default_BASEBALL_FUTURE" 3)
'("Default_BLDG_1695_1155A" 4)
'("Default_BLDG_1695_1155B" 5)
'("Default_BLDG_1695_1160B" 6)
'("Default_BLDG_1695_1160C" 1)
'("Default_BOUNDARY" 2)
'("Default_CENTERROW" 3)
'("Default_CONINDEXDES"	4)
'("Default_CONINTERDES" 5)
'("Default_CONTEXTDES" 6)
'("Default_ESMT" 1)
'("Default_EXEDGPVMT" 2)
); end list
); end setq

 (vl-load-com)

 (foreach lay Lst
   (if
     (not
(vl-catch-all-error-p
  (setq curLay(vl-catch-all-apply 'vla-Item
     (list(vla-get-Layers
	     (vla-get-ActiveDocument
		  (vlax-get-acad-object)))(car lay))))))
     (progn
(vla-put-Color curLay(cadr lay))
(setq fLst(list(cons 8(vla-get-Name curLay))))
(if
  (setq laySet(ssget "_X" fLst))
  (progn
    (foreach itm
	     (mapcar 'vlax-ename->vla-object 
                      (vl-remove-if 'listp 
                        (mapcar 'cadr(ssnamex laySet))))
      (vla-put-Color itm acByLayer)
    ); end foreach
  ); end if
); end progn
   ); end progn
 ); end if
); end foreach
 (princ)
 ); end of c:layd

insted of color to layer can we attach material name to particular layer then render by using lisp

You have 3/4 done it maybe a script will do

-layer

Color 1 BLDG_1695_1160C

Color 2 Default_BASEBALL

Color 3 Default_BASEBALL_FUTURE

Color 4 Default_BLDG_1695_1155A

etc etc

Default_BLDG_1695_1155B -- Color 5

Default_BLDG_1695_1160B -- Color 6

Last guy want to attach materials to solids on certain layers, can you make it with script?

July 2, 2008

Hi ASMI,

Thanks for ur reply.While running the script the folowing error is displaying,

error: no function definition: VLA-GET-MATERIALS

Can u help in resolving this.

Regards,

Shamsam1

July 2, 2008

Oops!

Exuse me. Please add (vl-load-com) expressions to begin or end of file. VLA-functions don't work without it. Or copy listing one more time. I just add it.

July 2, 2008

after adding (vl-load-com) at the begning still i am getting same error..

my knowlede of lisp is nill

this is where i have modified

(defun c:pumat(/ Lst sSet mLst cMat sCnt lCnt mCnt eCnt)

(vl-load-com)

(setq Lst (list

'("Layer1" "APE BUMP")

); end list

); end setq

VLA-GET-MATERIALS is error i get again

July 2, 2008

I think Mechanical 2000 is a reason That's a pity, but I can't test it with this Autodesk product. I know that Object Model of Autodesk Mechanical has the big distinctions from plane AutoCAD or ADT. But I try to help you. Please type in command line (vl-load-com), than copy to command line:

(vlax-dump-object(vla-get-ActiveDocument(vlax-get-acad-object))t)

Press F2 and get long list of properties and methods of Mechanical 2000 document like this (from plane 2008 ).

That is weird. 'Materials' collection and 'ActiveMateial' properties missed I don't know how to help you You can open Developer Help>ActiveX andVBA Refference>Properties and try to find 'Materials property'. If it is I want to look owner objects. Like in usual Autocad:

Returns the materials collection for the database.

See Also | Example

Signature

object.Materialsobject

Database, Document

The object or objects to which this property applies.

It can't work in 2005. I don't know in how version Materials collection becomes accessible to Visual LISP. Maybe in 2007 (R 17.0)?
