The attached MirroredPart11.sldprt has config specific custom properties set that I wish to read. The file was created by the assembly mirror feature. Unfortunately the GetAll and Get4 methods are not returning anything. That is unless you do a File->Properties->Ok. Are there any API methods I can call to have SW recalc the custom properties?

Sub main()

    Dim App As SldWorks.SldWorks

    Dim Doc As ModelDoc2

    Dim CustPrpMan As CustomPropertyManager

    Set App = Application.SldWorks

    Set Doc = App.ActiveDoc

    Set CustPrpMan = Doc.Extension.CustomPropertyManager("d01")

    Dim PropNames, PropTypes, PropValues As Variant

    Debug.Print CustPrpMan.GetAll(PropNames, PropTypes, PropValues)

    Dim i As Long

    For i = 0 To CustPrpMan.Count - 1

        Debug.Print PropNames(i); PropTypes(i); PropValues(i)

    Next

End Sub
