Model leader note annotation point collection

[wmgshurik]

Hello friends!

I don't undarstand, why this code doesnt work.

I catch Argument Exception in .ModelLeaderNotes.CreateDefinition method.

If "ObjectCollection objects" has one point - it works, if it has more points - not works..

All points lie on the same plane. Documentation says thet Inventor project this points on the plane.

public void CreateTechNumberAnnotation(DependencyObjects DO, ComponentOccurrence occ)
{
    AssemblyComponentDefinition topCompDef = occ.Parent;

    WorkPlane workPlane;
    WorkPoints workPoints;
    if (occ.ReferencedFileDescriptor.FullFileName.EndsWith("iam"))
    {
        workPoints = ( (AssemblyDocument)occ.Definition.Document ).ComponentDefinition.WorkPoints;
    }
    else
    {
        workPoints = ( (PartDocument)occ.Definition.Document ).ComponentDefinition.WorkPoints;
    }

    //occ original point
    occ.CreateGeometryProxy(workPoints[1], out object temp);
    var workPointProxy = (WorkPointProxy)temp;
    GeometryIntent intentRoot = topCompDef.CreateGeometryIntent(workPointProxy);

   //occ last point
    Point endPoint = DO.TG.CreatePoint(workPoints[1].Point.X + 10, workPoints[1].Point.Y + 10, workPoints[1].Point.Z);
    workPoints.AddFixed(endPoint);

    endPoint = DO.TG.CreatePoint(workPoints[workPoints.Count].Point.X, workPoints[workPoints.Count].Point.Z,                workPoints[workPoints.Count].Point.Z);
    workPoints.AddFixed(endPoint);

    occ.Definition.Document.Update2();

    occ.CreateGeometryProxy(workPoints[workPoints.Count - 1], out temp);
    var workPointProxyText = (WorkPointProxy)temp;
    GeometryIntent intentText = topCompDef.CreateGeometryIntent(workPointProxyText);

    occ.CreateGeometryProxy(workPoints[workPoints.Count], out temp);
    var workPointProxyTextEnd = (WorkPointProxy)temp;
    GeometryIntent intentTextEnd = topCompDef.CreateGeometryIntent(workPointProxyTextEnd);

    workPlane = topCompDef.WorkPlanes[3];
    AnnotationPlaneDefinition annotationPlaneDef =         topCompDef.ModelAnnotations.CreateAnnotationPlaneDefinitionUsingPlane(workPlane);

    ObjectCollection objects = DO.InvApp.TransientObjects.CreateObjectCollection();
    objects.Add(intentTextEnd);
    objects.Add(intentText);
    objects.Add(intentRoot);

    ModelLeaderNoteDefinition leaderDef = topCompDef.ModelAnnotations.ModelLeaderNotes.CreateDefinition(objects, "Text", annotationPlaneDef);
    topCompDef.ModelAnnotations.ModelLeaderNotes.Add(leaderDef);
}

According to my understanding of the ModelLeaderNotes.CreateDefinition Method only the last item in the collection (even if it is the only item) can be a GeometryIntent object. The rest should be Point objects. 

Let me know if that works for you.

You are absolutely correct!

Thank you very much!

That is the code

public void CreateTechNumberAnnotation(ComponentOccurrence occ, string techNumber)
{
    if (techNumber == string.Empty) { return; }
    AssemblyComponentDefinition topCompDef = occ.Parent;
    Application invApp = occ.Application;
    TransientGeometry tg = invApp.TransientGeometry;

    WorkPoints workPoints;
    if (occ.ReferencedFileDescriptor.FullFileName.EndsWith("iam"))
        workPoints = ( (AssemblyDocument)occ.Definition.Document ).ComponentDefinition.WorkPoints;
    else
        workPoints = ( (PartDocument)occ.Definition.Document ).ComponentDefinition.WorkPoints;

    //occ original point
    occ.CreateGeometryProxy(workPoints[1], out object temp);
    var workPointProxy = (WorkPointProxy)temp;
    GeometryIntent intentRoot = topCompDef.CreateGeometryIntent(workPointProxy);

    //text point
    Matrix rootPosition = occ.Transformation;
    double textX = rootPosition.Cell[1, 4] + 30;
    double textY = rootPosition.Cell[2, 4] + 30;
    double textZ = rootPosition.Cell[3, 4];
    Point endPoint = tg.CreatePoint(textX, textY, textZ);

    //annotation plane will parallel to front view
    WorkPlane workPlane = topCompDef.WorkPlanes[3];
    AnnotationPlaneDefinition annotationPlaneDef = topCompDef.ModelAnnotations.CreateAnnotationPlaneDefinitionUsingPlane(workPlane);

    ObjectCollection objects = invApp.TransientObjects.CreateObjectCollection();
    objects.Add(endPoint);
    objects.Add(intentRoot);

    ModelLeaderNoteDefinition leaderDef =  topCompDef.ModelAnnotations.ModelLeaderNotes.CreateDefinition(objects, techNumber, annotationPlaneDef);
    ModelLeaderNote modelLeaderNote = topCompDef.ModelAnnotations.ModelLeaderNotes.Add(leaderDef);

    string name = techNumber + $"___suff{DateTime.Now:ffff}"; 
    modelLeaderNote.Name = name;
}
