IFC server roadmap and limits

Roadmap

Planned. The months are targets, reviewed on 2026-10-25; this list changes when the plan does.

1. Oct 2026

   Started

   IFC reader and writer, geometry, test-fit engines, document writers, licensing and updates: built and tested.

2. Oct 2026

   Beta

   Signed beta builds: a Claude Desktop bundle, a Cowork plugin and an npm package. Version 0.2.0 opens, asks, checks, repairs, edits, draws and exports IFC models from the assistant.

3. Nov 2026

   Generate and hand over

   Test fit and generate from the assistant, so one session can open, ask, change, generate, document and hand over.

4. Dec 2026

   Public release

   The MCP plugin, the product pages and pricing.

5. 2027

   Depth

   Detailed authoring (curtain walls, stairs, MEP and structure), sections and elevations, the full Revit path through IFC export, owner handover with IDS, BCF and COBie, and large models.

Limits: the gap list

What NativeBIM does not do yet, stated before you find it. Reviewed 2026-10-25.

• The tools. Version 0.2.0 serves the tools in the tool reference. The test-fit, generate, build-plan and view tools are designed and answer NB_TOOL_UNAVAILABLE until they ship. bim_edit changes and moves elements and adds or removes doors, windows and openings, but does not build walls, slabs, columns, spaces, stories or grids yet.
• Authoring depth. The builder writes walls, slabs, roofs, columns, doors, windows, grids and spaces. Site paving and parking are in development. Stairs, curtain walls, ceilings, families and type catalogs, MEP and structural framing are not covered.
• Documentation depth. bim_drawing draws a floor plan on an ARCH D sheet as PDF or SVG; schedules export as XLSX or CSV. Area plans and schedules on sheets, other sheet sizes and DXF sheets are in development. Elevations and sections, revisions and the Portland correction cycle, and MEP and structural sheets are planned.
• Exact geometry. Plan cuts, areas and quantities use NativeBIM's own mesh and 2D polygon geometry. Exact B-rep operations and STEP export through the NativeCAD kernel are planned.
• Native Revit. Metadata only. There is no direct Revit geometry import; full models come through Revit's IFC export.
• Pre-release schemas. IFC4X3 release candidates and earlier 4.x builds open as IFC4X3_ADD2 with a warning. A check that flags values in entities that changed between versions is planned.
• Permits. None of the six Oregon permit offices whose pages we read on 2026-10-22 lists IFC models as an accepted submittal; Portland's file standards list PDF and 2D DWF. NativeBIM's sheets are drafts for the licensed professional of record and are marked NOT FOR CONSTRUCTION by default.
• Codes. Zoning and code tables cover Portland, Oregon, for named editions. Some code-table values were read from secondary transcriptions and are flagged unverified in the output. Screening results are drafts.
• Scale and collaboration. One user on one machine. Large-model streaming, concurrency, merge and a remote server are planned.
• Assistants. Results depend on the assistant you connect. The BIM-Edit benchmark in the numbers on the front door shows language models fail often on IFC edits; the engine rejects invalid edits but cannot supply intent.
• Standards. IFC5 is not supported. buildingSMART International has not reviewed or endorsed NativeBIM.
