Read why creating rules for IfcEntities in IDS is insufficient and how the PredefinedType could be an alternative. Moreover get a list of translated PredefinedTypes to ease your start.
Thank you for your contribution IFC and the thoughts on the IFC and IFC predefined type to advance the automation of model utilisation with IDS. I agree with your assessment. Predefined types should definitely be used in the model exports in the IFC standard. PredefindType correspond to a constructive, universal logic and help to utilise the model even before the assignment of correct classifications. Entities, PredifinedType and Material (product assignment) also make it possible to deal with incompletely classified models. Entities, PredefinedType and Material are closer to the modelling than classifications, the classifications can also be applied to the models later depending on the model use (construction cost planning, building physics, ...).
