Convert Objects in Symbol to ByClass

[Pat Stanford]

This script was written based on a query in another forum:

https://techboard.vectorworks.net/ubbthreads.php?ubb=showflat&Number=218975#Post218975

Procedure SymbolContentsToByClass;

{If the selected object in a drawing is a symbol, it locates the}
{symbol definition and converts all objects inside the definition}
{to use the ByClass option for all attributes}

Var H1, H2, H3: Handle;
SymDefName: String;

Begin

     H1:=FSActLayer;

     If GetType(H1)=15 then
	Begin
	  SymDefName:=GetSymName(H1);

Just tried this and it works! Is it easy to change this script it's inverse? (i.e.Remove all "by-class" settings of objects in a symbol).

Boh,

   There may be a more elegant way to remove the Attributes-By-Class setting for selected objects, but I can't find it.  I can only do it by removing each attribute individually. Here's a script to that effect.

 

   This will work on multiple selected symbols, but not on nested symbols. If a symbol definition contains other symbol instancess, they will not be affected. You will have to run this script on instances of each symbol  you want to convert. You can place them in the drawing, select them all, then run the script once.

 

   After this script is run, you will not see any differences in the symbol's appearance. The objects inside will have the same attributes as the classes they are in. However, if you then change the appearance of a controlling class, these symbols will not follow the new class appearance since their contents no longer are set By-Class. I hope this is what you were looking for.

That is brilliant Raymond! Thank you. Perfect for me as I am sorting out my library of symbols so very useful.

 

[MullinRJ]

You're welcome.

@MullinRJ - This is fantastic, and in fact is really close to what I was recently looking for in this thread.

 

Any way to adjust the script so that it works on all symbol definitions in the current file's RM, rather than on selected objects? If not, this will make due in the meantime.

 

Alternatively, I wonder if there's a script that inserts one instance of every symbol definition into the document, which could be ran first? [EDIT - This script does the job]

Hi @Andy Broomell ,

   Yes, with some minor changes to the preceding script, the following script "should" convert the entire Symbol Library, but there are no guarantees. I will leave it to you to tell me if it works. It's 2 AM and I only whimsically ran this script through its paces, meaning I tried it once, it ran, and I posted it below. I did test it on Symbols stored in Folders and it appears to work. Try it on COPIES of your working files several times before committing to your real work.

 

Procedure AllSymbolContentsNotByClass;
{ This script converts every object inside all symbol definitions }
{ to REMOVE the SetByClass option for all object attributes. }

	function RemoveSetByClass(SymH :Handle) :Boolean;
	Var
		H: Handle;
		B, visibility :Boolean;
		thickBasis, angul, Opasity, PenOp, FillOp :Integer;
		style, Red, Grn, Blu :Longint;

					B := SetObjEndMarker(H, style, angul, size, wydth, thickBasis, thickness, visibility);

			{	For VW 2016 and earlier, use the following for Opacity: }
			{	GetOpacity(H, Opasity);	}
			{	SetOpacity(H, Opasity);	}
		
			{	For VW 2017 and later, use the following for Opacity: }
				if GetOpacityN(H, PenOp, FillOp) then
					B := SetOpacityN(H, PenOp, FillOp);

				H := NextObj(H);
			end;		{ while (H <> Nil) }
			ResetObject(SymH);
		end;		{ if }	
	End;		{ RemoveSetByClass }


BEGIN
	ForEachObjectInList(RemoveSetByClass, 0, 2, FSymDef);
	SysBeep;		{ make noise when done }
END;

Good night, and good luck,

The first time I tried it something weird happened (might've been unrelated to script), but then I restarted VW and it worked fine in all subsequent tests. Thanks Raymond!!
