How can I access subobject in Plant3d from CSharp?

Anonymous — Tue, 20 Nov 2012 13:25:05 GMT

I have a program in C# where i am trying to access a sub-object which is of type Connectors/fasteners.

In a drawing, I have an object with class (PnPClassname) P3dConnector, and when I click on it's red circle with <ctrl> pressed, I access an object with class (PnPClassname) BoltSet. I have added the event oDatabase.ObjectModified, but this only access the P3dConnector-object, not the BoltSet-object. See the image and attached file.

How can i access this sub-object? I have tried to loop through prompted result set using SelectAll. The P3dConnector-object is listed but not the BoltSet-object.

I am able to access the object by using following code:

using (Transaction tx = objId.Database.TransactionManager.StartTransaction())
{
    DBObject dbObject = tx.GetObject(objId, OpenMode.ForRead);
    Autodesk.ProcessPower.PnP3dObjects.Connector Conn = tx.GetObject(objId, OpenMode.ForRead) as Autodesk.ProcessPower.PnP3dObjects.Connector;

    if (Conn != null)
    {
      foreach(Autodesk.ProcessPower.PnP3dObjects.SubPart sp in Conn.AllSubParts)
      {
        MessageBox.Show(sp.GetType().ToString());
      }
    }
}

But the Conn.Id is 0. How do i get the object from a sub part?
