Hello:
There is a difficult when I change the UnitSystem of a model by weblink：
there is my code：
var unit=TempModel.GetPrincipalUnits(); //get the Unitsystem of template model
var model=oSession.CurrentModel;
var Options=pfcCreate("pfcUnitConversionOptions").Create(pfcCreate("pfcUnitDimensionConversion").UNITCONVERT_SAME_SIZE);
model.SetPrincipalUnits(unit,Options);
when I run this code，promp an error：XToolkitBadInputs
Could anyone help me？Thanks very much！
