Get Point X Y 2D

I see the manual but don't see the method 'Point2dFromXY'

What programming language are you using?

You're calling the VBA COM InterOp from C# from a separate process (i.e. a EXE).

I want to get the 2D coordinates of the element

All DGN coordinates are 3D, even when in a 2D model.  The Z value is zero in 2D.

I strongly suggest that you write a prototype of your app. using VBA.  Move it to C# once the VBA is working correctly.

Different element types have different ways of getting coordinates.  A TextElement or CellHeaderElement has an Origin property. Linear elements implement the IVertexList interface.

I get the element's X Y coordinate but it returns null

Code C#

void Test(string sPath)
{
    MicroStationDGN.Application app = new MicroStationDGN.Application();
    DesignFile dgnfile = app.OpenDesignFile(sPath, true);
    ElementScanCriteria _MSesc = new ElementScanCriteria();

    _MSesc.ExcludeAllTypes();
    _MSesc.IncludeType(MsdElementType.msdElementTypeLine);
    //_MSesc.IncludeType(MsdElementType.msdElementTypeLineString);
    
    _Element ele;
    ElementEnumerator ee = app.ActiveModelReference.Scan(_MSesc);

    while (ee.MoveNext())
    {
        ele = ee.Current;
             
        int iVectorCount = ele.AsLineElement.VerticesCount;

        Array xPoint = ele.AsLineElement.GetVertices();
        string sTEXT = ""; 


        for (int i = 0; i < iVectorCount; i++)
        {
            sTEXT += ", i = " + i 
            + " : X = " + xPoint.GetValue(0)
            + ", Y = " + xPoint.GetValue(1)
            + ", Z = " + xPoint.GetValue(2)
            ;
        }

        MessageBox.Show("sTEXT = " + sTEXT);

    }
}
