Export Parameter setting lost after adding user parameter to a custom parameter group

By Wayne Brill

Issue

I create a Custom Parameter Group to contain certain user parameters. The custom parameter group is created correctly however the user parameters do not retain the export parameter setting. (This applies to the 2009 release of Inventor).

Solution

A workaround is to restore the export parameter property by setting the ExposedAsProperty property of the parameter object (the equivalent to this export parameter check mark in the Parameters dialog) after it is added in the custom parameter group. The below VB.Net code demonstrates this suggestion:

Sub CreateCustomParaGroup()

 

    Dim oCustomParameterGroup As CustomParameterGroup

    Dim oParams As Parameters

    Dim oDoc As PartDocument

 

    oDoc = _invApp.ActiveDocument

    oParams = oDoc.ComponentDefinition.Parameters

 

    oCustomParameterGroup = oParams. _

   CustomParameterGroups.Add("LVA_VCC", "LVA_VCC")

 

    Dim oParameter As UserParameter

    For Each oParameter In oParams.UserParameters

 

        Dim oStr As String = oParameter.Comment

        oStr = oStr.Substring(0, 3)

 

        If oStr = "LVA" Then

 

            Dim oExported As Boolean

            oExported = oParameter.ExposedAsProperty

            oCustomParameterGroup.Add(oParameter)

            oParameter.ExposedAsProperty = oExported

 

        End If

    Next

 

End Sub
