HOW TO AUTOMATE UDF REFERENCE SELECTION USING VB.API

HOW TO AUTOMATE UDF REFERENCE SELECTION USING VB.API

Hello All,

     I have created a VB.API program for the customization of an assembly. In this i have used a UDF to create a set of Co-ordinate system which is driven through excel. But the problem what i am facing here is when the  Co-ordinate get created using the UDF each time i have to manually choose the Reference Co-ordinate system.  How can i make that a single selection process.

Below i am giving the codes, Please guide on this.

  Public Function createHoleUDFInPart(ByVal placementModel As IpfcSolid, _

                                        ByVal Name01 As String, _

                                        ByVal csysName As String, _

                                        ByVal Dim1 As Double, _

                                        ByVal Dim2 As Double, _

                                        ByVal Dim3 As Double, _

                                        ByVal Dim4 As Double, _

                                        ByVal Dim5 As Double, _

                                        ByVal Dim6 As Double, _

                                        ByVal aseemblycount As Integer) _

                                        As IpfcFeatureGroup

        Dim csys As IpfcCoordSystem = Nothing

        Dim cSystems As IpfcModelItems

        Dim i As Integer

        Dim udfInstructions As IpfcUDFCustomCreateInstructions

        Dim csysSelection As IpfcSelection

        Dim csysReference As IpfcUDFReference

        Dim references As CpfcUDFReferences

        Dim variantDims As IpfcUDFVariantDimension

        Dim variantDims2 As IpfcUDFVariantDimension

        Dim variantDims3 As IpfcUDFVariantDimension

        Dim variantDims4 As IpfcUDFVariantDimension

        Dim variantDims5 As IpfcUDFVariantDimension

        Dim variantDims6 As IpfcUDFVariantDimension

        Dim Coname As String

        Dim variantVals As IpfcUDFVariantValues

        Dim group As IpfcFeatureGroup

        Try

            cSystems = placementModel.ListItems(EpfcModelItemType.EpfcITEM_COORD_SYS)

            Coname = "ACS" + Convert.ToString(aseemblycount)

            For i = 0 To cSystems.Count - 1

                If (cSystems.Item(i).GetName.ToString = "ASM_CSYS") Then

                    csysName = "ASM_CSYS"

                    csys = cSystems.Item(i)

                    Exit For

                End If

            Next

            If csys Is Nothing Then

                Throw New Exception("Coordinate System not found in current Solid")

            End If

            udfInstructions = (New CCpfcUDFCustomCreateInstructions).Create("CSYS")

            udfInstructions.DimDisplayType = EpfcUDFDimensionDisplayType.EpfcUDFDISPLAY_BLANK

            csysSelection = (New CMpfcSelect).CreateModelItemSelection(csys, Nothing)

            csysReference = (New CCpfcUDFReference).Create("Reference Coordinate System", csysSelection)

            references = New CpfcUDFReferences

            references.Set(0, csysReference)

            udfInstructions.References = references

            variantDims = (New CCpfcUDFVariantDimension).Create("d0", Dim1)

            variantDims2 = (New CCpfcUDFVariantDimension).Create("d1", Dim2)

            variantDims3 = (New CCpfcUDFVariantDimension).Create("d2", Dim3)

            variantDims4 = (New CCpfcUDFVariantDimension).Create("d3", Dim4)

            variantDims5 = (New CCpfcUDFVariantDimension).Create("d4", Dim5)

            variantDims6 = (New CCpfcUDFVariantDimension).Create("d5", Dim6)

            variantVals = New CpfcUDFVariantValues

            variantVals.Set(0, variantDims)

            variantVals.Set(1, variantDims2)

            variantVals.Set(2, variantDims3)

            variantVals.Set(3, variantDims4)

            variantVals.Set(4, variantDims5)

            variantVals.Set(5, variantDims6)

            udfInstructions.VariantValues = variantVals

            references.GetHashCode()

            group = placementModel.CreateUDFGroup(udfInstructions)

            Return group

        Catch ex As Exception

            MsgBox(ex.Message.ToString + Chr(13) + ex.StackTrace.ToString)

            Return Nothing

        End Try

    End Function

End Class

Re: HOW TO AUTOMATE UDF REFERENCE SELECTION USING VB.API

I am also trying to automate the placement of udf features. The problem is that I still have to select the references in the model even though I am passing them in as CpfcUDFReferences. Is there a proper example of how this works so the user does not have to select the references? Or is there a settting that needs to be triggered?

 

Thanks!

Re: HOW TO AUTOMATE UDF REFERENCE SELECTION USING VB.API

I believe I have found the solution to this problem. After the CreateModelItemSelection line I added a line highlighting the selection.

 

csysSelection = (New CMpfcSelect).CreateModelItemSelection(csys, Nothing) 'Existing line

csysSelection.Highlight(EpfcStdColor.EpfcCOLOR_SELECTED) 'Added line
