GUID's are an essential component of collaborative BIM and ALICE retains the GUID's coming from BIM model and uses it to keep track of Elements and their parameters; both imported from the model as well as UDF's generated in ALICE. This also helps in tracking changes in elements during design revisions and change management.
ALICE requires to explode or ungroup all Groups and Arrays in Revit, to be able to read individual GUIDs of all elements.
