HFSS - Import .igs file for HFSS

Import .igs file for HFSSI need help to import a .igs file for HFSS.
When I go in modeler import, call the .igs file it aparace with the dimensions, but put in the properties where it says: position, XSIZE, Ysize and Zsize not appear. Appears: command - import; coordinate system - Global; source file - the site where it saved the file.
How do I get the dimensoe and coordinates appear as if drawing in HFSS own?
