IFC Writer Global ID and GUID

When 12d exports an IFC file each object is given a unique GUID. If you export the same data again, the new IFC is created at a different point in time so each object is given a new and unique GUID. This can create problems for other software, such as Navisworks, as the GUID is [...]
