General joint stiffness worksheet through Mechanical scripting

How can I create a general joint and define its stiffness coefficients in the worksheet through ACT scripting?

To define the general joint, use:

    connections = ExtAPI.DataModel.Project.Model.Connections
    newJoint = connections.AddJoint()
    newJoint.Type =JointType.General
    newJoint.Rotations=JointRotationDOFType.FreeAll

To define the stiffness coefficients, use the following syntax (for example for thetaX) :

    ws= newJoint.BushingWorksheet
    ws.SetBushingStiffnessPerThetaUnitX(3,10)

Hi Pernelle, a follow up question on this topic. Is it possible to add nonlinear (tabular) stiffness coefficients to the bearing via scripting?
