v0.4.0

What's new in 0.4.0

Stratigraphic units, PyArchInit and BIM

• US forms: open, edit and create us_table records from the interface, with the stratigraphic relationships stored in PyArchInit's own format (its Harris matrix reads them).
• 3D proxies of stratigraphic units: each unit polygon becomes a closed solid between the DEM and a base (plane, later DEM, constant thickness or lowest point), with volume, plan area and elevations; Extended Matrix OBJ export; publication as a 3D media linked to the US.
• IFC export with progress and preview; proxy solids carry quantities for take-off (Qto_PyArchInit_US: volume, area, height, elevations), materials, period/phase groups and the stratigraphic relationships (IfcRelConnectsElements). See docs/bim.md.
• Layer attributes are editable; changes to PyArchInit units are written back.

Integrations

• Live QGIS project: orthophoto, DEM and every drawn layer, refreshed in QGIS while you draw.
• Imports: Metashape .psx projects (cameras, calibration, markers, tie points, model, DEM/orthomosaic), WebODM/ODM tasks, Photo3D sessions; ppg photo3d-job runs as a Photo3D engine.
• Segment Anything 2.1 in the packaged application: installed on first use in a separate environment.

Fixes

• Cut/fill volumes: excavated and filled volumes were swapped when a reference surface was given; edge cells are now weighted by polygon coverage.
• The PyPI packages now include the PyArchInit schema and the logo: pip installs could not create the demo database.
• Qt's standard buttons are in Italian like the rest of the interface.
