Edge connection endpoint behaviour missing from GH

[lorinczandrea]

Note 1:

This feature exists in the API, but hasn't been implemented in the Grasshopper toolkit yet.

femdesign-api/FemDesign.Core/Shells/EdgeConnectionBase.cs

Lines 9 to 19 in 82dbe19

	public partial class EdgeConnectionBase: EntityBase
	{
	[XmlAttribute("moving_local")]
	public bool MovingLocal { get; set; } // bool. Default false according to strusoft.xsd but true in GUI?
	[XmlAttribute("joined_start_point")]
	public bool JoinedStartPoint { get; set; } // bool. Default false according to strusoft.xsd but true in GUI?
	[XmlAttribute("joined_end_point")]
	public bool JoinedEndPoint { get; set; } // bool. Default false according to strusoft.xsd but true in GUI?
	}

Note 2:

EdgeConnection.JoinedStartPoint and EdgeConnection.JoinedEndPoint properties must be true by default, as they are in FEM-Design.

FEM-Design functionality:

Tasks

• Add new parameters to the existing EdgeConnection constructor or create a new one or add a new method to the class to set the endpoint behaviour attributes.

femdesign-api/FemDesign.Core/Shells/EdgeConnection.cs

Lines 78 to 89 in 82dbe19

	private EdgeConnection(Releases.RigidityDataType3 rigidity, string libraryName = null)
	{
	this.EntityCreated();
	this.MovingLocal = false;
	this.JoinedStartPoint = true;
	this.JoinedEndPoint = true;
	if (libraryName is null)
	this.Rigidity = rigidity;
	else
	this.PredefRigidity = new Releases.RigidityDataLibType3(rigidity, libraryName);
	}

EdgeConnection.MovingLocal, EdgeConnection.JoinedStartPoint and EdgeConnection.JoinedEndPoint should be added to the constructor as input parameters. E.g.:

private EdgeConnection(Releases.RigidityDataType3 rigidity, string libraryName = null, bool movingLocal = false, bool joinedStartPoint = true, bool joinedEndPoint = true)
        {
            EntityCreated();
            MovingLocal = movingLocal;
            JoinedStartPoint = joinedStartPoint;
            JoinedEndPoint = joinedEndPoint;

            if (libraryName is null)
                this.Rigidity = rigidity;
            else
                this.PredefRigidity = new Releases.RigidityDataLibType3(rigidity, libraryName);
        }

• The MovingLocal property controls the functionality shown in the picture below:

• Create a new "EndPointBehaviour" GH component.

• Update existing EdgeConnection GH components (EdgeConnection.Construct, EdgeConnection.Hinged, EdgeConnection.Rigid). Add "EndPointBehaviour" as an input parameter.

• Update EdgeConnection.Deconstruct

• Notify the user! Discourse ticket

If the property is accessible in C#, we can give a user a simple c# or Python component to set the properties.

step:
Place a Python component and connect the edge edge connection into "x"

Inside the Python component you should be able to write:

x.JoinedStartPoint = True
