[CONNECT C#] How can I get subelements from complex elements

Hi,

you may want to check the CurveVector for an element, here a small code snippet to extract subelements from a complexShape

ComplexShapeElement cShape;
//...
CurveVector curve = cShape.GetCurveVector();
for (int i = 0; i < curve.Count; i++)
{
    CurvePrimitive prim = curve.GetPrimitive(i);
    MessageBox.Show(prim.GetCurvePrimitiveType().ToString());
    DEllipse3d arc;
    if (prim.TryGetArc(out arc))
    {
        MessageBox.Show("Arc with Length (UOR): " + arc.ArcLength().ToString());
    }

}

I hope this helps?

Best regards,
Artur

Hi Artur,

many thanks. Another question, do you know how to get level name from Grouped Hole in CONNECT and NET API? 

Hi artur,

Do you have any code snippets or  suggestions how to extract geometry infomation from mesh or solid elements?

Hi,

In previous MicroStation versions elements of type "Grouped Hole" were handled like a  type 2 cell elements without providing level info for the cell instance element.
With MSCE a Grouped Hole element also provides a level info, which obviously is missing in .NET API.
The same result I can reproduce with COM API.

I have filed the Defect # 867376 to address this issue.

Best regards,
Artur

Hi Arrtur,

maybe ElementGraphicsProcessor can help?

I tried it, but even though AnnounceElementDisplayParameters method is called for every "cell element" (boundary and groupped holes), it always reports boundary level name for all subelements, which is wrong, because in my example the holes are in a different level with different symbology.

But maybe another ElementGraphicsProcessor method should be overriden too?
