IfcProcess

Definition from IAI: An action taking place in building construction with the intent of designing, costing, acquiring, constructing, or maintaining products or other and similar tasks or procedures. Processes are placed in sequence (including overlapping for parallel tasks) in time, the relationship IfcRelSequence it used to capture the predecessors and successors of the process. Processes can have resources assigned to it, this is handled by the relationship IfcRelAssignsToProcess.

> HISTORY New entity in IFC Release 1.0.
