What It Does Together: web-ifc parses IFC files in the browser; xeokit renders them in high-performance 3D. Combined, they produce a zero-install model review platform functional on tablets in bright outdoor conditions.
Setup Complexity: Low. Both have npm packages with extensive documentation. A junior developer can assemble a working prototype in 2-3 days. No build servers or desktop installation required.
Maturity Assessment: Production-ready. Both tools have active commercial deployments, enterprise support options, and comprehensive API documentation. The pairing has passed the "brave pioneer" stage.
PGC Application: Replace iPad Navisworks sessions with a browser app that loads project IFC files, highlights glazing panels by zone, and captures field photos linked to specific elements.
What It Does: Full-featured BIM authoring with IFC import/export, quantity takeoff, and schedule generation. The BIM workbench specifically targets AEC workflows rather than mechanical modeling.
Setup Complexity: Medium. Desktop installation required; available for Windows, macOS, and Linux. Learning curve of 1-2 weeks for team members familiar with AutoCAD. BIM-specific tutorials available on the FreeCAD YouTube channel.
Maturity Assessment: Stable for preliminary design and quantity extraction. Not a Revit replacement for full construction documentation, but sufficient for PGC's pre-construction and bidding workflows where glazing contractors typically engage.
PGC Application: Extract glass area, frame linear footage, and hardware quantities directly from architect IFC files during bid preparation. Output schedules in IFC or CSV formats compatible with estimating tools.
What It Does: Processes laser scan point clouds, compares them against reference geometry (including BIM models), and generates deviation reports highlighting installation quality.
Setup Complexity: Medium. Desktop application with standard installation process. Point cloud processing requires understanding of scan registration and coordinate systems—typically a 1-day training investment.
Maturity Assessment: Mature and field-proven. Used by surveying and geomatic professionals for years; IFC comparison plugins represent recent additions specifically relevant to AEC.
PGC Application: Request point cloud scans from trade partners on curtain wall projects. Use CloudCompare to verify installed positions against BIM model coordinates and generate QA documentation for architects and owners.
