[MSCE update 13 C++/C#] How can I create sheet from seed

Last Chance said:

I tried DgnFile.CreateNewModel, It seems as if that the seed model does not work

Hi Jon,

Thanks for you reply.

I tried two ways, but none works.

First:

            DrawComPropData drawComPropData = DrawCompPropHolder.Instance.GetDrawComPropData();
            Bentley.DgnPlatformNET.IDisposableEnumerable<Bentley.Internal.MstnPlatformNET.DrawingSeedDescriptor> drawingSeedDescriptorEnum = Bentley.Internal.MstnPlatformNET.DrawingSeedDescriptorList.GetFromDgnLibs("", "", Bentley.Internal.MstnPlatformNET.DrawingSeedDim.DRAWINGSEEDDIM_All);
            foreach (Bentley.Internal.MstnPlatformNET.DrawingSeedDescriptor drawingSeedDescriptor in drawingSeedDescriptorEnum)
            {
                if (drawComPropData.ModelName == drawingSeedDescriptor.ViewName)
                {
                    Bentley.DgnPlatformNET.DgnModel seedModel = null;
                    Bentley.DgnPlatformNET.ModelId modelId = drawingSeedDescriptor.DrawingSeedFile.FindModelIdByName(drawComPropData.ModelName);
                    //seedModel = drawingSeedDescriptor.DrawingSeedFile.FindLoadedModelById(modelId);
                    Bentley.DgnPlatformNET.StatusInt status = Bentley.DgnPlatformNET.StatusInt.Error;
                    seedModel = drawingSeedDescriptor.DrawingSeedFile.LoadRootModelById(out status, modelId);
                    if(status == Bentley.DgnPlatformNET.StatusInt.Error)
                    {
                        MessageBox.Show("LoadRootModelById Seed Failed");
                        return false;
                    }
                    Bentley.DgnPlatformNET.DgnModel dgnModel = Bentley.MstnPlatformNET.Session.Instance.GetActiveDgnFile().CreateNewModel(out modelStatus, "Extract_Model" + TimeString, DgnModelType.Sheet, false, seedModel);

                    if (modelStatus != DgnModelStatus.Success)
                    {
                        return false;
                    }
                }
            }
                    

Second:

DgnModelStatus modelStatus = DgnModelStatus.Success;
Bentley.DgnPlatformNET.DgnModel seedModel = null;
seedModel = GetSeedModel();
Bentley.DgnPlatformNET.DgnModel dgnModel = Bentley.MstnPlatformNET.Session.Instance.GetActiveDgnFile().CreateNewModel(out modelStatus, "Extract_Model" + TimeString, DgnModelType.Sheet, false, seedModel);

private Bentley.DgnPlatformNET.DgnModel GetSeedModel()
        {
        //Seed file, C:\Program Files\Bentley\Bentley Raceway and Cable Management CONNECT Edition\BRCM\Default\Dgnlib\DrawComp\en\DrawingSeed.dgnlib
            if(!System.IO.File.Exists(drawComPropData.SeedFileName))
            {
                return null;
            }
            Bentley.DgnPlatformNET.DgnFileOwner fileOwner = Bentley.DgnPlatformNET.DgnFile.Create(Bentley.DgnPlatformNET.DgnDocument.CreateForLocalFile(drawComPropData.SeedFileName), Bentley.DgnPlatformNET.DgnFileOpenMode.ReadOnly);

            Bentley.DgnPlatformNET.StatusInt status;
            Bentley.DgnPlatformNET.DgnFile dgnFile = fileOwner.DgnFile;
            dgnFile.LoadDgnFile(out status);
            if (Bentley.DgnPlatformNET.StatusInt.Success != status)
            {
                MessageBox.Show("Open File failed..." + drawComPropData.SeedFileName);
                return null;
            }
            string[] modelNames = drawComPropData.ModelName.Split('|');
            if(modelNames.Length < 2)
            {
                return null;
            }
            uint umodelId = 0;
            if(!uint.TryParse(modelNames[1], out umodelId))
            {
                return null;
            }
            Bentley.DgnPlatformNET.ModelId modelId = umodelId;
            Bentley.DgnPlatformNET.DgnModel dgnModel = dgnFile.LoadRootModelById(out status, modelId);
            if (Bentley.DgnPlatformNET.StatusInt.Success != status || dgnModel == null)
            {
                return null;
            }

            return dgnModel;
        }

And when the code works, I should get a new sheet model like create sheet model from seed

Thanks.

Hmm.  Quite complex code. You're using undocumented internal code, about which anybody outside Bentley Systems (i.e. me) cannot comment.

Does this work (from SDK example ParametricModellingExample)?

defModel = activeFile.CreateNewModel(out status, modelName, DgnModelType.Normal, true, null);

The null parameter for seed model reference means 'use the default model'.  If that works, you can try to obtain a seed model reference another way.

Hi Jon,

Thanks for your reply.

These two way is difference way to get the seed model.

And I tried thes method with seed model null, but the result is not the one I need.

Let's take the seed file 

C:\Program Files\Bentley\MicroStation CONNECT Edition\MicroStation\Default\Dgnlib\DrawComp\en\DrawingSeed.dgnlib

for example

If I create sheet model from seed and the model choose metric sheet only, when click the OK button from the dialog of create model, I will see the border of the seed sheet, but when I do this with code, the border does not show.

Yes, I appreciate that.  My suggestion was to help you ensure that the method CreateNewModel produces a useful result.

If that worked, then you can go about obtaining a seed file model another way.

Perhaps you need to execute whatever code is required to Show Sheet Boundary?  You might like to investigate the SheetDefinition you can get using  ModelInfo.GetSheetDefinition, then look at its properties, particularly SheetDefinition.BorderAttachmentId.

It may be helpful, as Jan likes to remind us, to look in the C++ MicroStationAPI document.  Sometimes the help available there provides some clues, that are not mentioned in the .NET documentation, into class behaviour.

Thanks Jon, DgnModel.SetModelInfo(DgnModel.GetModelInfo()) works fine for me.

Thanks anyway.
