Never used it, but it still seems to be there:
Function GetRemainingDOFs(ByRef Rpoint1_status As Integer, ByRef Rpoint1 As SolidWorks.Interop.sldworks.MathPoint, ByRef Rdirection1_status As Integer, ByRef Rdirection1 As SolidWorks.Interop.sldworks.MathVector, ByRef Rpoint2_status As Integer, ByRef Rpoint2 As SolidWorks.Interop.sldworks.MathPoint, ByRef Rdirection2_status As Integer, ByRef Rdirection2 As SolidWorks.Interop.sldworks.MathVector, ByRef Tdirection1_status As Integer, ByRef Tdirection1 As SolidWorks.Interop.sldworks.MathVector, ByRef Tdirection2_status As Integer, ByRef Tdirection2 As SolidWorks.Interop.sldworks.MathVector) As Integer
Member of SolidWorks.Interop.sldworks.IComponent2
Not sure if it still works or not though.
thank you very much ! ....... this API has so many parameters that i would not use it ! is there a way to get the DOFs ?
