Using C++, I get the mass properties using:
_variant_t mprops = swDocExt->GetMassProperties(0, &swStat);
The mass properties are returned in metric units (as the documentation says). I want to convert mass to what the user sees when the Mass Properties button is pushed. There must be some "convert-to-user-units" API, but I have not found it. I don't want to write a general converter.
