Create mate constraint with bias points

By Xiaodong Liang

With the arguments BiasPointOne and BiasPointTwo in AddMateConstraint , the occurrences should be repositioned to make the two bias points coincident. The BiasPoint used by method AddMateConstraint should be from model space. So you need to use the native object of the point to add this constraint. The code below assumes that two faces and two vetex of different occurrences in an assembly context are selected.

Sub constraintWithBiasPoints()

      ' assume we have had the inventor application

    Dim oDoc As Document

    oDoc = _InvApplication.ActiveDocument

 

    Dim oDef As AssemblyComponentDefinition

    oDef = oDoc.ComponentDefinition

 

    Dim oFaceProxy1 As FaceProxy

    Dim oFaceProxy2 As FaceProxy

 

    Dim oPointProxy1 As VertexProxy

    Dim oPointProxy2 As VertexProxy

 

    oFaceProxy1 = oDoc.SelectSet(1)

    oFaceProxy2 = oDoc.SelectSet(2)

    oPointProxy1 = oDoc.SelectSet(3)

    oPointProxy2 = oDoc.SelectSet(4)

 

    oDef.Constraints.AddMateConstraint(oFaceProxy1, _

                                        oFaceProxy2, _

                                        0, _

                 InferredTypeEnum.kNoInference, _

                 InferredTypeEnum.kNoInference, _

                 oPointProxy1.NativeObject.Point, _

                 oPointProxy2.NativeObject.Point) 

End Sub
