Range edits: - next 16.2.1 -> 16.2.7 in apps/editor + apps/ifc-converter. 16.2.5/16.2.6 fixed six high-severity advisories (middleware bypass, DoS, SSRF, XSS, RSC cache poisoning); 16.2.7 is bugfix backports. No API/config changes. - typescript 6.0.2 -> 6.0.3 everywhere, including aligning the 5.9.3 stragglers (@pascal-app/mcp, @repo/ui, @repo/eslint-config) that date from the original scaffold and were never intentionally held back. - @types/node in @pascal-app/mcp: ^25.5.0 -> ^22.19.20 — mcp was the only workspace typed against non-LTS node 25; 22 matches the release workflow's node and every other workspace. - @number-flow/react ^0.5.14 -> ^0.6.0 (packages/editor, apps/editor); the only breaking change (removed --number-flow-char-height CSS var) is unused here. - agentation ^2.3.2 -> ^3.0.2 (apps/editor devtool; v3 is a drop-in for the props-less <Agentation /> usage, additions are opt-in). - Root overrides: @types/react 19.2.14 -> 19.2.17, @types/three 0.184.0 -> 0.184.1 (types-only fixes). Lockfile refresh within existing ranges picks up react 19.2.7 (pairs with next 16.2.7 — 19.2.6 had a server-action FormData regression), motion 12.40.0, three-mesh-bvh 0.9.10, @react-three/uikit-lucide 1.0.73, the June radix wave, lucide-react 1.17.0, zustand 5.0.14, tailwind-merge 3.6.0, geist 1.7.2 (fixes Geist Mono ligature regression), react-grab 0.1.44, biome 2.4.16 + ultracite 7.8.2, turbo 2.9.17. Held: three stays 0.184.0 (npm latest; single-instance constraint), tailwindcss 4.3.0 + lightningcss 1.32.0 already match the pinned optionalDependencies native binaries, eslint 10 major not taken (@repo/ui is unconsumed legacy scaffold). Verified: turbo build, check-types, biome check, and 931 package tests green; bun.lock stays lockfileVersion 1 (CI bun 1.3.0 compatible); single next/three resolution confirmed.

IFC → Pascal Converter
A web app that converts IFC building models into Pascal scene-graph JSON and
previews the result in the real @pascal-app/viewer. Drop in an .ifc file
(or pick a bundled example), inspect what was extracted, and download the
JSON to load into the Pascal editor.
⚠️ Early alpha
This converter is in early alpha. IFC is a sprawling, loosely-followed standard and real-world exports vary wildly — so expect rough edges: misplaced or missing elements, walls that default to a fixed height when their geometry can't be read, items skipped entirely, and element types that aren't mapped yet. The output is meant for previewing and iterating, not production.
Contributions very welcome — if you hit a file that converts badly, a sample IFC + a note on what's wrong is hugely helpful, and PRs improving the conversion (better geometry extraction, more element types, edge-case handling) are exactly what this needs. Jump in. 🙏
How it works
@pascal-app/ifc-converter(packages/ifc-converter) — the pure conversion logic. Parses IFC via web-ifc, maps elements onto Pascal node schemas from@pascal-app/core. No DOM, no React.- This app — the UI: drop zone, example picker, element search/filters, the 3D preview, and JSON download.
Develop
bun dev # from this directory, or `turbo run dev` at the repo root
The web-ifc.wasm binary is copied into public/ automatically on
install/dev/build (scripts/copy-web-ifc-wasm.mjs). Large example IFCs are
fetched from a public bucket at runtime; the small ones are committed under
public/test-ifc-files/. Override the bucket with
NEXT_PUBLIC_IFC_EXAMPLES_BASE_URL.
Known limitations (help wanted)
- Plain
IFCWALL(Brep/mapped geometry) falls back to a default height — exact per-wall heights need geometry-AABB extraction. - Items (furniture, etc.) are skipped — Pascal items require a catalog asset.
- Beams have no Pascal node type yet and are skipped.
- Doors/windows are matched to walls by proximity when the IFC omits fill relationships; matching isn't perfect.
- Stairs/roofs are placeholders (bounding box / flat polygon in metadata).
