You can determine which parcel segment elements make up a parcel by using the AeccParcel.ParcelLoops collection. This collection stores objects of type AeccParcelSegmentElement. Each parcel segment element contains a reference to the parent segment, so you can also determine which segments are used to create a parcel.
' Loop through all elements used to make parcel "oParcel" Dim i as Integer For i = 0 to oParcel.ParcelLoops.Count - 1 Dim oElement As AeccParcelSegmentElement Set oElement = oParcel.ParcelLoops.Item(i) Debug.Print "Element " & i _ & " of segment " & oElement.ParcelSegment.Name & ": " _ & oElement.StartX & "," & oElement.StartY & " to " _ & oElement.EndX & ", " & oElement.EndY If (TypeOf oElement Is AeccParcelSegmentLine) Then Dim oSegmentLine As AeccParcelSegmentLine Set oSegmentLine = oElement Debug.Print " is a line.
