[ORLD 2021 R2 C#] How to find alignment (complex geometry) for 3D Linear Enitty?

Hi Jan,

Here is the sample code which might help your requirement:

DgnModel dgnModel = Bentley.MstnPlatformNET.Session.Instance.GetActiveDgnModel();

DgnModel activeModel = Session.Instance.GetActiveDgnModel();

//get the elements from dgnModel

ModelElementsCollection elements = dgnModel.GetElements();

using (ConsensusConnection sdkCon = new Bentley.CifNET.SDK.ConsensusConnection(dgnModel))

{

//Iterate over the elements

foreach (Bentley.DgnPlatformNET.Elements.Element element in elements)

    {

    //Check If current element is Graphics

    if (element.IsGraphics)

        {

        Bentley.CifNET.GeometryModel.SDK.FeaturizedModelEntity fme = Bentley.CifNET.GeometryModel.SDK.FeaturizedModelEntity.CreateFromElement(sdkCon, element);

        //get objectkey for current element

        Bentley.CifNET.Objects.ObjectKey civilKey = Bentley.CifNET.Model.DataAccess.DgnPersistenceManager.GetInstance().ActiveConnection.GetECObjectKey(element);

        Bentley.CifNET.SDK.Edit.ConsensusConnectionEdit sdkConEdit = Bentley.CifNET.SDK.Edit.ConsensusConnectionEdit.GetActive();

        IObjectSpace sdkObjSpace = SDK.Edit.EditItemFactory.GetObjectSpace(sdkConEdit);

        if (civilKey == null || sdkObjSpace == null)

            {

            continue;

            }

        //get the GeometricEntity from the objectKey

        Bentley.CifNET.GeometryModel.GeometricEntity obj = sdkObjSpace.GetObject(civilKey) as Bentley.CifNET.GeometryModel.GeometricEntity;

        if (obj != null)

            {

            if (fme != null)

                {

                if (string.IsNullOrWhiteSpace(fme.FeatureName))

                    {

                    continue;

                    }

                try

                    {

                    Bentley.CifNET.GeometryModel.LinearEntity2dInPlan line2dEntity = obj as Bentley.CifNET.GeometryModel.LinearEntity2dInPlan;

                    Bentley.CifNET.GeometryModel.LinearEntity3d line3dEntity = obj as Bentley.CifNET.GeometryModel.LinearEntity3d;

                    if (line2dEntity != null)

                        {

                        if(line2dEntity.Geometry is LinearComplex)//Aligment

                            {

                                //...

                            }

                        }

                    else if (line3dEntity != null)

                        {

                        if (line3dEntity.BaseGeometry is LinearComplex)//Aligment

                            {

                            //...

                            }

                        }

                    }

                catch (Exception ex)

                    {

                    string exception = ex.ToString();                                   

                    }

                }

            }

        }

    }

}

Hi,

thanks a lot for your code

Meantime I found different solution / approach, where I start with GetAllGeometricModelsV2() method and I iterate the result. It provides information I need, but your code demonstrates some aspects that I maybe use in later steps in the code ;-)

It would be nice to have documentation / explanation of concepts like keys, objectspace etc. To work with ORD SDK is like to play with black box with no documentation, hoping the right buttons are pushed in the right order...

With regards,

  Jan

Hi Shasank,

I have been trying out this code for a similar application, but cant find where "EditItemFactory" comes from?

Shashank Gokhale said:

IObjectSpace sdkObjSpace = SDK.Edit.EditItemFactory.GetObjectSpace(sdkConEdit);

You can find it in: Bentley.CifNET.SDK.Edit.EditItemFactory

Try referring to:  Bentley.CifNET.SDK.Edit.4.0.dll

Excellent thanks. I didn't see it because i was using 10.10. Now available with the 10.11 SDK.
