supressing warning pop ups

[NemKumar]

Hi All,

I am trying to display a cylinder triangulation by modelCurve(line).

When each model curve is created and rendered, I get very annoying

warning popups saying "line is slightly off the axis........".

Here is the code for calculating normal

public static SketchPlane createSketchPlane(Document inDoc, Curve inCurve)
{
      Plane plane;

      // Linear curves have no "normal" returned by compute derivatives
      if (inCurve is Line)
      { 
            XYZ point1 = inCurve.GetEndPoint(0);
            XYZ point2 = inCurve.GetEndPoint(1);
            XYZ tangent = (point2 - point1).Normalize();
            // Vertical line
            if (tangent.IsAlmostEqualTo(XYZ.BasisZ) || tangent.IsAlmostEqualTo(-XYZ.BasisZ))
            {
                   plane = inDoc.Application.Create.NewPlane(XYZ.BasisX, point1);
            }
            // Non-vertical line, use cross product with vertical to generate normal vector
            else
            { 
                   XYZ yVector = tangent.CrossProduct(XYZ.BasisZ).Normalize();
                   plane = inDoc.Application.Create.NewPlane(tangent, yVector, point1);
            }
       }
       // Non-linear curve supplies normal for sketch plane
       else
      {
             XYZ point = inCurve.Evaluate(0, true);
             Transform transform = inCurve.ComputeDerivatives(0, true);
             XYZ normal = transform.BasisZ;
             plane = inDoc.Application.Create.NewPlane(normal, point);
       }

       return inDoc.Create.NewSketchPlane(plane);
}

Also I tried to suppress warning by using this class

public class WarningSwallower : IFailuresPreprocessor
{
        public FailureProcessingResult PreprocessFailures(FailuresAccessor a)
        {
                // inside event handler, get all warnings

               IList<FailureMessageAccessor> failures = a.GetFailureMessages();

               foreach (FailureMessageAccessor f in failures)
               { 
                     FailureDefinitionId id = f.GetFailureDefinitionId();
                     if (BuiltInFailures.RoomFailures.RoomNotEnclosed == id)
                     a.DeleteWarning(f);
                }
                return FailureProcessingResult.Continue;
          }
}

and use this class as in 

public static void setFailureDialogSuppressor(Transaction tranasaction)
{
         FailureHandlingOptions failOpt = tranasaction.GetFailureHandlingOptions();
         failOpt.SetFailuresPreprocessor(new WarningSwallower());
         tranasaction.SetFailureHandlingOptions(failOpt);
}

and i make call it after

using (Transaction trans = new Transaction(mRevitDoc.Document))
{
       trans.Start("create Triangles");
       CFRevitGraphicsUtility.setFailureDialogSuppressor(trans);

       .....

       trans.Commit()

}

I need to fix this urgently as I dont have much time left.

I am not able to figure out what am I missing or doing wrong.

As I am creating 100s of cylinders, it popsup for 100s of times.

I dont know how to disable or suppress it.

OR fix the warning itself.

solution for either of the problem will be helpful.

Thanks in Advance.

And what If you change your warning swallower to :

public FailureProcessingResult PreprocessFailures(FailuresAccessor a)
{
IList<FailureMessageAccessor> failures = a.GetFailureMessages();

foreach (FailureMessageAccessor f in failures)
{
FailureDefinitionId id = f.GetFailureDefinitionId();

FailureSeverity failureSeverity = a.GetSeverity();

if (failureSeverity == FailureSeverity.Warning)   //simply catch all warnings, so you don't have to find out what warning is causing the message to pop up
{
a.DeleteWarning(f);
}
else
{
return FailureProcessingResult.ProceedWithRollBack;
}
}
return FailureProcessingResult.Continue;
}
