NwcIO v0.9.0

Major Additions & Capabilities

• 4D TimeLiner XML Serialization & Exchange (NwcTimeLinerXmlSerializer):
  • Full reading and writing of Autodesk Navisworks TimeLiner Exchange XML format (<exchange> schema).
  • WBS task hierarchies with nested subtasks, planned/actual dates, duration tracking, planned and actual costs, and percentage progress.
  • Roundtrip persistence of attached Selection Set names and explicit attached node IDs.
  • Direct integration into NwcDocument (ExportTimeLinerXml, ImportTimeLinerXml) and NwcAssembly (ExportTimeLinerXml, ImportTimeLinerXml).
• Automated Rule-Based Schedule Linking (NwcTimeLinerLinker):
  • AutoLink: Automated binding of 4D TimeLiner tasks to model geometry using matching Selection Set or Search Set names (task.AttachedSelectionSetName or task.Name).
  • Resolves explicit node IDs from NwcSelectionSet and evaluates dynamic condition queries from NwcSearchSet.
  • LinkByNodeName: Direct fuzzy or exact name matching against scene graph elements.
• Multi-Discipline Coordination Clash Matrix (NwcClashMatrix, NwcClashDiscipline, NwcClashMatrixCell):
  • Execution of comprehensive $N \times M$ BIM clash coordination matrices across discipline models (Architecture, Structure, MEP, etc.).
  • Automated matrix population from federated assembly models (NwcClashMatrix.CreateFromAssembly).
  • Spatial pruning and double-precision AABB intersection penetration calculation.
  • Ignore rules evaluation (same layer, same file, tolerance thresholds).
  • Formatted Markdown coordination summary table generation (ToMarkdownTable).
  • Structured JSON report export (SaveJson, ExportClashMatrixJson).
  • Unified buildingSMART BCF 2.1 zip archive export (SaveBcf, ExportClashMatrixBcf), creating issue topics with 3D camera viewpoints and highlighted IFC components for coordination in Revit, Solibri, and BIMcollab.
• Interactive 4D TimeLiner & Selection Sets HTML WebGL Viewer (NwcHtmlViewerExporter):
  • Integrated 4D TimeLiner playback controller with Play/Pause button, timeline slider scrubber, dynamic date label, and speed multiplier (1x, 5x, 15x, 60x).
  • Dynamic 3D simulation color coding: active construction glowing green ([0.2, 0.95, 0.2]), demolition highlighted red ([0.95, 0.2, 0.2]), temporary elements yellow, and unstarted elements hidden from the render loop.
  • Interactive Selection Sets sidebar tab (#tab-sets) rendering hierarchical folder trees and selection items with instant 3D model highlighting on click.
• CLI Enhancements (nwcio):
  • Added --timeliner-xml <file.xml>: Export or import 4D TimeLiner schedule exchange XML.
  • Added --link-timeliner: Automatically links schedule tasks to Selection Sets, Search Sets, or element names.
  • Added --clash-matrix <file.json>: Executes multi-discipline coordination matrix and exports JSON report.
  • Added --clash-matrix-md <file.md>: Exports clash matrix coordination report as Markdown table.
  • Added --clash-matrix-bcf <file.bcfzip>: Exports clash matrix conflicts to buildingSMART BCF 2.1 zip archive.
