IfcPlaneAngleMeasure
Definition from ISO/CD 10303-41:1992: A plane angle measure is the value of an angle in a plane.
Usually measured in radian (rad, m/m = 1)
NOTE: IfcPlaneAngleMeasure is used where angles need to be described
to an accuracy of less than one degree and expressed as decimal parts of an angle. It is widely
used for angular measurement except for situations where accuracy needs to be defined using arc
measurement; for which purpose the IfcCompoundPlaneAngleMeasure is provided.
