Delete existing DGN model

The existing dgn model can be deleted from the current dgn file. The below code snippet shows how this can be achieved.

Example


internal bool DeleteExistingDGNModel()
        {
            //Get active dgn file
            DgnFile dgnFile = Bentley.MstnPlatformNET.Session.Instance.GetActiveDgnFile();
            //get model id by name
            ModelId modelId = dgnFile.FindModelIdByName("SampleModel");
            //Get DgnModel from Id
            DgnModel modelToDelete = dgnFile.FindLoadedModelById(modelId);

            //delete model
            StatusInt statusdelete = dgnFile.DeleteModel(modelToDelete);
            if (StatusInt.Success != statusdelete)
                return false;
            return true;
        }

To delete an existing model from active dgn file use DeleteModel().
