 {"id":"ifcurl-p60","title":"Viewer: no element click-to-identify — can't get GlobalId or properties","description":"There is no way to click on a mesh in the viewer and see which IFC element it represents. Reviewers can see geometry but cannot reference specific elements — they can't discover a GlobalId to put in a selector URL, can't see the element name/type/Psets, and can't say 'this specific wall' in a BCF or Forgejo comment. This breaks the collaboration workflow at its foundation: every useful feedback comment needs to identify specific elements. Need: click or hover on a surface to highlight it and show a properties panel (name, type, GlobalId, key Psets). The GlobalId should be copyable into the selector field or URL.

 {"id":"ifcurl-m0y","title":"Phase 4: Bonsai integration — open ifc:// URLs natively","description":"Bonsai (the Blender-based IFC authoring tool) should be able to receive and handle ifc:// URLs natively, delegating all git fetch/cache/reconstruction work to the ifcurl Python library.\n\n## What Bonsai needs to implement\n\n**1. ifcurl library integration**\nBonsai calls ifcurl.resolve(url) → local IFC file path, and ifcurl.parse(url) → view state (camera position/direction/up, selector expression, visibility mode, clipping planes). The ifcurl library handles all transport, caching, and file reconstruction — Bonsai sees only a local path.\n\nIf the ifcurl library is not installed, all ifc:// features degrade gracefully: menu entries are hidden or disabled, CLI URL arguments are ignored with a logged warning, and BCF export omits ifc:// fields silently. No errors or broken UI.\n\n**2. 'Open ifc:// URL…' operator and menu entry**\nA Blender operator that accepts an ifc:// URL string, resolves it via ifcurl, opens the resulting IFC file, and applies the view state (camera, selector, visibility). Exposed as a menu entry (File \u003e Open ifc:// URL…) so users can paste a URL directly. This is also the entry point used when launched from ifcurl-open. Hidden when ifcurl is not installed.\n\n**3. CLI / launch argument handling**\nWhen Bonsai is launched with an ifc:// URL as a CLI argument (forwarded by ifcurl-open), the add-on detects it and invokes the same operator. ifcurl-open always launches a new Bonsai instance — there is no mechanism to send a URL to an already-running instance. Silently ignored if ifcurl is not installed.\n\n**4. 'Copy view URL' action**\nSerialise the current Bonsai camera position, active selector/filter, and visibility state into an ifc:// URL pointing to the current file's git repo and ref. Requires the file to have been opened from a git-tracked location. Hidden when ifcurl is not installed.\n\n**5. BCF viewpoint embedding**\nWhen Bonsai exports a BCF file, viewpoints that reference a git-tracked IFC file should include an ifc:// URL in the viewpoint metadata alongside the standard BCF camera fields. Omitted silently when ifcurl is not installed.\n\n**6. Federation: IFCDOCUMENTREFERENCE resolution**\nWhen Bonsai encounters an IFCDOCUMENTREFERENCE whose Location is an ifc:// URL, call ifcurl.resolve() to fetch and open the referenced model. This is the long-term federation goal. Falls back to ignoring the reference when ifcurl is not installed.\n\n## Out of scope here\n- The ifcurl Python library API itself (ifcurl.resolve, ifcurl.parse) — that is Phase 1 work\n- OS handler registration (ifcurl-coh) and dispatcher (ifcurl-7db)","status":"open","priority":2,"issue_type":"feature","owner":"bruno@postle.net","created_at":"2026-06-07T07:20:36Z","created_by":"Bruno Postle","updated_at":"2026-06-07T07:39:58Z","dependency_count":0,"dependent_count":0,"comment_count":0}

 {"id":"ifcurl-bsw","title":"Socket IPC: dispatch ifc:// URLs to already-running viewer instance","description":"When a viewer (bonsai or ifcviewer) is running, ifcurl-open should send the URL to the existing instance rather than launching a new process. Protocol: on startup the viewer opens a Unix socket at ~/.cache/ifcurl/\u003cviewer-name\u003e.sock. ifcurl-open tries the socket first; if it connects it sends the URL as a newline-terminated string and exits. If no socket exists or connection fails, falls back to launching fresh. Bonsai and ifcviewer each need to implement the socket listener.","status":"closed","priority":3,"issue_type":"feature","owner":"bruno@postle.net","created_at":"2026-06-05T14:43:06Z","created_by":"Bruno Postle","updated_at":"2026-06-07T07:34:25Z","closed_at":"2026-06-07T07:34:25Z","close_reason":"Descoped: ifcurl-open will always launch a new viewer instance. Socket IPC is complex, not idiomatic for Blender, and can be added later if there is demand.
