Major Additions & Capabilities

  • 4D Construction Sequencing & Temporal Simulation (IfcWorkSchedule, IfcTask, IfcTaskTime / IfcIO.Model.Sequence):
    • Full support for construction work schedules (IFCWORKSCHEDULE), WBS hierarchies, task durations, milestones, and predecessor/successor relationships (IFCRELSEQUENCE with FinishToStart, StartToStart, FinishToFinish, StartToFinish).
    • Elements assigned to construction tasks via IFCRELASSIGNSTOPROCESS.
    • Temporal 4D simulation engine: query active tasks (GetActiveTasksAt), element simulation states (GetElementStateAt: NotStarted, Planned, InProgress, Completed), and overall schedule progress (GetProgressAt) at any given simulation date.
    • Interactive 4D timeline simulation playback integrated into the standalone 3D HTML viewer (IfcHtmlViewerExporter).
  • 5D Cost Planning & CBS Budgeting (IfcCostSchedule, IfcCostItem, IfcCostValue / IfcIO.Model.Cost):
    • Hierarchical Cost Breakdown Structure (CBS) supporting predefined schedule types (Budget, CostPlan, Estimate, Tender, Actual, Valuation, Pricing).
    • Unit rates, quantities, and automatic cost rollups across hierarchical tree nodes (item.TotalCost, cs.GetTotalCost()).
    • Applied monetary value breakdown components conforming to IFCAPPLIEDVALUE.
    • Element assignments and physical quantity bindings via IFCRELASSIGNSTOCONTROL.
    • Full STEP physical file roundtrip serialization and deserialization for IFC4 and IFC2x3.
  • Spatial Zones (IfcZone / IfcIO.Model):
    • Functional spatial zone grouping conforming to IFCZONE (inherits IfcGroup) for architectural spaces and rooms.
    • Support for thermal, fire safety, acoustic, security, and ventilation zone classifications.
  • Bi-directional buildingSMART BCF 2.1 Archive Container (BcfArchive / IfcIO.Bcf):
    • Full in-memory or stream-based container for reading, querying, editing, and saving .bcfzip archives.
    • High-level queries by element GUID (archive.FindTopicsByElement), status (archive.FindTopicsByStatus), and topic manipulation (AddTopic).
    • Complete snapshot image encoding/decoding (snapshot.png) and viewpoint camera handling.
  • High-Level IfcOpenShell-Compatible API Facade (IfcApi / IfcIO.Api):
    • High-level, script-like API facade inspired by IfcOpenShell API conventions:
      • IfcApi.Sequence: AddWorkSchedule, AddTask, AssignProcess, AddSequence.
      • IfcApi.Cost: AddCostSchedule, AddCostItem, AssignCostControl, AssignQuantity.
      • IfcApi.Spatial: AddZone, AssignContainer.
      • IfcApi.Root: CreateProject, CreateStorey, CreateWall, CreateSlab, CreateColumn, CreateBeam.
  • CLI Command Expansion (IfcIO.Cli):
    • ifcio schedule: temporal 4D construction schedule simulation with --sim-date <date> and --export-csv <file.csv>.
    • ifcio cost: 5D cost breakdown and budget reporting with --export-csv <file.csv>.
    • ifcio bcf: inspect BCF 2.1 coordination archive topics, status, and viewpoints.
