The reason of having that strange list of units is that they are taken from IGES standard (IGES 5.3, 2.2.4.3.14). Actually, IGES is not limited to that list and supports any units defined according to MIL12 or IEEE260 standards (this corresponds to enum value 3 -- in that case unit is defined by name). STEP supports many more units. Hence, it is quite logical to improve OCCT translators to support wider set of units.

Vico, do you have access to the mentioned standard (IEEE260) that can be used as reference?
