IGES Unit conflict

Game Milky's picture
Forums: 

Dear Users and supervisors!

I have a problem with IGES import unit difference. The unit i am getting using

Handle(IGESData_IGESModel) model;
model = Handle(IGESData_IGESModel)::DownCast(reader.Model());
IGESData_GlobalSection gs = model->GlobalSection();
cout

and from what i am reading from specification of IGES is quite different.

For example, i am using IGES 5.2.

Result from OCC
6------mm
2------m

Specification

6------m
2------mm

what is wrong here? Does anybody face the same?
Regards

Game
