Mit BIM-and® allows you to create your own psets and properties.
BIM-and® supports all datatypes available for an IFC schema.
Of course you may define user privileges for userdefined psets and assign those psets
to selected IFC entities in your projects.
…. and finally BIM-and® allows you to edit their values!
All changes in your IFC files can be saved as new revisions to plain IFC files!
