Get DrawingCurves from occurrence (C#)

[Anonymous]

In a drawing I'm looking for components that have a certain iProperty.  If they have the iProperty, I want to turn every occurrence of that item red.

I can get the occurrences fine, but I'm unable to properly get the drawing curves so I can turn them red.  I'm using code from this post on ModTheMachine: http://modthemachine.typepad.com/my_weblog/2010/10/changing-drawing-curves-to-match-assembly-color.h...

Here's my code:

private static void ProcessAssemblyColor(DrawingDocument aDoc, ComponentOccurrences occurrences)
{
   foreach (ComponentOccurrence occ in occurrences)
   {
      if (occ.DefinitionDocumentType == DocumentTypeEnum.kPartDocumentObject)
      {
         TransientObjects transObjects = StandardAddInServer._mInventorApplication.TransientObjects;
         LayersEnumerator layers = aDoc.StylesManager.Layers;
         Layer colorLayer = layers[1];

         colorLayer.Color = transObjects.CreateColor(255, 0, 0); //red
         colorLayer.LineType  = LineTypeEnum.kContinuousLineType;
         colorLayer.LineWeight = 0.02;

         ObjectCollection objColl = transObjects.CreateObjectCollection();

         foreach (DrawingView drawView in aDoc.ActiveSheet.DrawingViews)
         {
            DrawingCurvesEnumerator drawingCurves = drawView.DrawingCurves[occ]; //This line throws invalid Args error

            foreach (DrawingCurve drawingCurve in drawingCurves)
            {
               foreach (DrawingCurveSegment segment in drawingCurve.Segments)
               {
                  objColl.Add(segment);
               }
            }
            aDoc.ActiveSheet.ChangeLayer(objColl, colorLayer);
         }
      }
      else
      {
         ProcessAssemblyColor(aDoc, (ComponentOccurrences)occ.SubOccurrences);
      }
   }
}

 I've seen some things say I need to use an out object to use DrawingCurves.  If that's true, I'm not sure what to put for the first variable.

object outObject;
DrawingCurvesEnumerator drawingCurves = drawView.DrawingCurves[occ.CreateGeometryProxy(whatgoeshere?, out outObject)];

I'm open to other methods of turning components red in a drawing, but this is what appeared tio be the suggested method.

Hi,

the first argument is the native object you want to create proxy for. please refer to this post to get the idea:
