Suggest using either edge splitting by absence of condline or presence of line. I believe prior is done by LDView
The angle threshold for smoothing is very large (< 90 degrees) and doesn't do much in practice, so I may just end up removing it. I split any of the line type 2 edges. I've found defining the set of "sharp" edges to be easier to work with when triangulating the faces. I haven't checked if the absence of an optional line always indicates the presence of a line for all LDraw part files.
