{"id":"ifcurl-dag","title":"Viewer: no model metadata panel — disciplines, spatial structure, element counts","description":"Beyond individual element selection, reviewers and designers need a model overview: what disciplines/types are present, how many elements, what building storeys exist, what's the spatial structure (site/building/storey/space hierarchy). A collapsible side panel showing IFC spatial tree and type breakdown would give immediate context and allow navigating by storey or discipline. Without this, reviewers must already know the model structure before opening the viewer.","status":"closed","priority":3,"issue_type":"feature","assignee":"Bruno Postle","owner":"bruno@postle.net","created_at":"2026-04-24T11:04:55Z","created_by":"Bruno Postle","updated_at":"2026-04-25T19:04:25Z","started_at":"2026-04-25T18:38:17Z","closed_at":"2026-04-25T19:04:25Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}
{"id":"ifcurl-ov6","title":"Viewer selector only supports type names — property filters require server round-trip","description":"The viewer's applySelector() only supports IFC type names and their unions ('IfcWall+IfcSlab'). Full IfcOpenShell selector syntax — filter by property value (Pset_WallCommon.FireRating=2HR), by GlobalId, by name (.Name='Core Wall'), by spatial containment — is not supported. For collaboration, reviewers need to select specific elements ('all walls with fire rating 2HR that aren't compliant') not just all walls. The service's /preview endpoint already handles full selector syntax server-side. The viewer should forward complex selectors to the service and use the rendered image, or fetch the matching GlobalIds from a new /resolve-selector service endpoint and apply them in the viewer.","status":"closed","priority":3,"issue_type":"feature","assignee":"Bruno Postle","owner":"bruno@postle.net","created_at":"2026-04-24T11:04:38Z","created_by":"Bruno Postle","updated_at":"2026-04-25T19:19:28Z","started_at":"2026-04-25T19:15:47Z","closed_at":"2026-04-25T19:19:28Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}

It is not shown on the file history page (the list of commits that touched a file), which is where users naturally go to see how a model evolved over time. Each entry in the history list already has a commit hash in its href. Injecting a 'View in 3D' link or button alongside each history entry would let reviewers quickly compare model states across commits — which is a primary collaboration use case.","status":"closed","priority":3,"issue_type":"feature","assignee":"Bruno Postle","owner":"bruno@postle.net","created_at":"2026-04-24T11:04:23Z","created_by":"Bruno Postle","updated_at":"2026-04-24T14:04:56Z","started_at":"2026-04-24T13:21:51Z","closed_at":"2026-04-24T14:04:56Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}

A reviewer wanting to see 'what did this look like on main before the PR' or 'show me the v1.2 tag' must manually edit the URL. For a collaboration tool, being able to flip between 'current PR branch' and 'base branch' at the same camera view is essential for review.

In corporate BIM environments with restricted internet (common in construction/engineering), the viewer will fail to load entirely. There is no documented self-hosted path.

IFC files in real projects are often 20–200MB. The fetch() call and the web-ifc WASM parser both block for seconds with no visual feedback. A progress bar or percentage indicator during fetch (using response.body ReadableStream + Content-Length header) and a spinner during parse would prevent users abandoning the page thinking it crashed. The status element exists and is already used — it just needs richer updates.","status":"closed","priority":3,"issue_type":"task","assignee":"Bruno Postle","owner":"bruno@postle.net","created_at":"2026-04-24T11:03:58Z","created_by":"Bruno Postle","updated_at":"2026-04-24T11:47:23Z","started_at":"2026-04-24T11:14:56Z","closed_at":"2026-04-24T11:47:23Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}
