Hello, I must write a converter from LandXML to our own data structure. This includes conversion of the values into meter and radians. Since the units are specified within the Units tag, this should not be a problem. However, in LandXML specification, there is an elevationUnit and a heightUnit. Which one is used for which values? I think about elevation of contours, axis profile elevation, elevation of CgPoints, elevation of surface points, and so on. I am unsure, because those unit types accept different sets of values. Are there also elevation/height values, which should be converted by the linearUnit? Is it possible to mix up metric and imperial units, e.g. use feet for the linearUnit, but celsius for the temperatureUnit? Regards, Johann
