Unsing C++ API ConvertUnits function.

[yeasayer]

Hi My name is WJ lee, KOREA.

I Tried to convertUnits using convertUnits function.

In Basic I just convert unit like below.

oVolume_temp = oPartDoc(i).MassProperties.Volume
oVolume(i) = oPartDocument.UnitsOfMeasure.ConvertUnits(oVolume_temp, "cm cm cm", "m m m")

But in C++

pPartDocument->UnitsOfMeasure()->ConvertUnits(Volume_size_temp, "cm cm cm", "m m m", Volume_size);

There is an compile error

error 1 error C2664: 'Inventor::UnitsOfMeasure::ConvertUnits' : can not change bariable 2 from  'Inventor::UnitsTypeEnum' to 'const VARIANT &' e:\project\inventor api\simpleexe\stltranslate.cpp 121

What do i put VARIANT?

there is no help for VARIANT.

Thanks for reading.
