A3DEUnits

enum A3DEUnits

Unit values used for model files.

Units in a model file are stored as a double value representing millimeters (mm).

For example, a value of 1000 mm corresponds to a meter (:ref:kA3DUnitMeter).

Below is a table showing the correspondence between units and their values in millimeters:

It is possible to convert a double value to an A3DEUnits with A3DUnitGetFromValue(), and back to A3DDouble with A3DUnitGetFromEnum().
