System.Reflection.TargetInvocationException: 'Exception has been thrown by the target of an invocation.'

[GRamsaroep]

Hi,

When i try to edit the input of the members of the example, i get errors everytime running the code. For example: i want to show the beams M4, M1 and M2. I changed the code and added one member extra to the ones that are needed to be shown. But everytime when i run the code, it doesnt work and get stuck at the Invoke methode. It gives the following error:

System.Reflection.TargetInvocationException: 'Exception has been thrown by the target of an invocation.'

KeyNotFoundException: The given key was not present in the dictionary.

Even when i just want to show member M1 it still gives an error. I think its the problem with the point maybe, because when i didnt change the point node (connection node) it worked with just showing the 2 members M1 and M3.

i have seen that it goes wrong when i change the members only, the starting node connection has no influence i think. it goes wrong at the Import methode. Is give me the same error every time.

methodImport.Invoke(obj, array);

This is the full details:

System.Reflection.TargetInvocationException HResult=0x80131604 Message=Exception has been thrown by the target of an invocation.

If key is not in the dictionary it iom is not created correctly - the problem is on your side. To be able to faind the problem we need to check your data (your iom model)

This i what i have changed only. THe member 1 to member 4

//member1D 4 var member4 = openModel.Member1D.Find(x => x.Id == 4); IdeaRS.OpenModel.Connection.ConnectedMember conMb4 = new IdeaRS.OpenModel.Connection.ConnectedMember { Id = member4.Id, MemberId = new ReferenceElement(member4), IsContinuous = true, }; connection.ConnectedMembers.Add(conMb4);

        IdeaRS.OpenModel.Connection.BeamData beam4Data = new IdeaRS.OpenModel.Connection.BeamData
        {
            Name = "M4",
            Id = 4,
            OriginalModelId = member4.Id.ToString(),
            IsAdded = false,
            MirrorY = false,
            RefLineInCenterOfGravity = false,
        };
        openModel.Connections[0].Beams.Add(beam4Data);

it seems member #1 is still referenced in your model by any other entity. You can not change id without other changes in your model

I will paste the whole code underneath the Fill fucntion. The other code isn't changed. I thought it works like this: The other functions, like AddNodes, AddMembers etc, will "Load" an geometry with Loads and members in the project and the Fill command will fill in the project with members chosen from the loaded model at the background. Because i wanted to test is i commented all the other code so only the members first will be projected in the file and after that i wanted to make the steps to add plates and bolts etc by hand.

What changes do i need to make then?
