1.0.23 beta

ESRI export:
SLPK layers are now global by default (WGS 84, EPSG:4326). Vertices are transformed from the CRS the IFC files declare, so the model appears in its place in ArcGIS global scenes over world imagery and terrain. It matches PROJ to below 1 mm, for 568 projected EPSG CRSs. A local layer in the declared CRS or another EPSG code is still available: i3sOutputWkid in the converter, or Referencing in xeoIFC Web. See esri/README.md

1.0.22 beta

Improve geo-referencing for ESRI export

1.0.21 beta

Cap triangulation settles: the Delaunay flip pass now runs up to 1024 sweeps instead of stopping at 64. The early stop left needle triangles that the exit weld dropped, opening the cap

1.0.20 beta

Add C# WPF example

1.0.19 beta

CLI: merged outer-shape IFC:
several -i with an IFC -o without {name} now writes one merged IFC instead of being refused

1.0.18 beta

I3S from IfcSite: .slpk output no longer refuses files without a declared CRS

1.0.16 beta

• improve extractOuterShape feature
• add direct .i3s (slpk) export, combined with extractOuterShape

1.0.15 beta

• improve extractOuterShape feature
• add i3s export

1.0.14 beta

• xeoIFC Qt is open source (MIT). xeoifc-qt-source.zip has Visual Studio and CMake projects plus the xeoIFC library for Windows x64, Linux x64 and Linux ARM64. The app now also runs on Linux.
• Licence: all binaries use the xeoIFC Testing License (testing and evaluation). Saves without a licence key carry the evaluation marker.
• Faster CSG on models with many openings: optional seam repairs share a time budget.
• Fixes from a code review: document IDs no longer collide, a batch can no longer close its own document and stop the server, stricter file-access checks, Qt export fixes.
