Connect to active Geometric model in DGN file

Every DGN has at least one Model. When you execute code withing a DGN, it considers current DGN to get models for further activities. At least one civil object should be present in the model to get the active geometric model, otherwise the function GetActiveGeometricModel() returns null. The below code snippet shows how to get Geometric model from current dgn.

Example


internal bool ConnectToActiveGeometricModel()
        {
            //Get Connection to Active DGN
            Bentley.DgnPlatformNET.DgnModel activeModel = Bentley.MstnPlatformNET.Session.Instance.GetActiveDgnModel();

            //Create ConsensusConnection object
            Bentley.CifNET.SDK.ConsensusConnection con = new Bentley.CifNET.SDK.ConsensusConnection(activeModel);

            //Get active Geometric model
            Bentley.CifNET.GeometryModel.SDK.GeometricModel geomModel = con.GetActiveGeometricModel();
            if (geomModel == null)
                return false;

            return true;
        }
