I trying to get the boundary of a block with a xclip boundary with the following code but xData turns up always turns up empty (no error). d1(0).ObjectName = AcDbSpatialFilter 'So I know I'm getting the extension dictionary correctly, I think Can anyone shed light? Thanks, Ted WD Partners Dim d1 As AcadDictionary Dim i As LongDim Dim xData As Variant Dim xType As Variant Set d1 = xref.GetExtensionDictionary("ACAD_FILTER") d1.GetXData "SPATIAL", xType, xData For i = 0 To UBound(xData) Debug.Print xData(i) Next i
