Full Version: perpendicular isoparms surface

Is there a word for a surface where every U isoparm is perpendicular to every V isoparm everywhere that U and V cross? Like a surface where if I do Construct > Curve > Iso > Both at any point then the resulting U and V curves will be at right angles at that point?

Hmmm, not that I can remember right now.
