Could someone please explain to me what the IFC_WORKSET or IFC_PROJECT in v8i exactly does? The documentation says by setting the variable to 1, dataset extended with IFC psets. But what does this actually mean and for what reasons would
# Enables the Dataset to be extended to include IFC2x3 property sets.
# IFC_WORKSET=0, dataset not extend,
# IFC_WORKSET=1, dataset extended with IFC psets
# IFC_WORKSET=2, dataset extended with IFC psets Plus FM Handover(COBie)
