Archicad AI Pilot— MEPbridge ACAIstr | Version v0.1.6 , Precise Reliable I/O & End-to-End [ad]

Bleufeng — Thu, 08 Oct 2026 09:34:25 GMT

Archicad is a future-ready 3D design software built specifically for architects. However, interdisciplinary collaboration and integration between architecture, MEP and other disciplines remain a long-standing bottleneck limiting its widespread adoption across the industry. This project addresses a persistent industry pain point: cross-disciplinary coordination between architectural and MEP teams within Archicad has not been widely adopted among design teams. With the rise of AI, Blender, Rhino and Revit have rolled out MCP-based automation capabilities, which motivated me to build this tool in spare time. While it cannot yet fully support end-to-end real-world building projects, it has achieved a critical breakthrough: AI can read all parameters stored in design files and trigger corresponding software operations. The full technical potential of this solution remains to be explored, driven by the evolution of large language models and continuous feature expansion. Its core mission is to provide architects with an open, experimental technical path to explore AI-augmented design. As a standalone Archicad MCP connector, the tool features two operation modes: AI-driven intelligent workflow and manual command control. It also comes with an extensible platform for user custom extensions. MEPbridge ACAIstr is open-source and available on GitHub: [https://github.com/bleufeng/mepbridge-acaistr](https://github.com/bleufeng/mepbridge-acaistr)

Re: Archicad AI Pilot— MEPbridge ACAIstr | Version v0.1.2 Release, Read/Write & Automation Valid

Bleufeng — Tue, 18 Aug 2026 05:41:24 GMT

v0.1.2 -Changed
Installation guides document the Node.js prerequisite, custom install paths, and a full step-by-step manual installation procedure covering administrator rights, locating the Archicad folder, choosing between Archicad 28 and 29, handling a previous build, and verifying the result.
The registered command and descriptor counts now come from a single ai-adapter/command-boundary.json file that the release gate, the public repository validator, CI, and the packaging scripts all read, instead of each carrying its own copy.
Command examples no longer contain hardcoded MEP system names or attribute indexes. Those identifiers are not stable across projects, locales, or Archicad versions, so omitting them lets the Add-On use the domain default. A static check keeps them out.
The Archicad runtime regression now checks returned content rather than only that response fields exist, and covers the favourite, layer-batch and classification write commands end to end, each restoring what it changed.
The internal command guide lists all 74 registered commands. It had 52, so the favourites, profile, view-map, classification and layer commands were absent along with the project and story queries. Command counts there now defer to ai-adapter/command-boundary.json.
The public repository validator no longer aborts on a Markdown link containing a stray percent sign; such a link is reported as broken instead.

claude is also working on this, what s the difference?

This refers to Claude Design? While Claude, GPT and Gemini already have their respective native MCP connections, they lack professional parsing for Archicad’s internal models. From an architectural‑specialty perspective, our goal is to add a dedicated BIM‑MCP vertical‑adaptation layer for Archicad, translate complex BIM model data into structured data readable by any large language model, and provide open, customizable extensions for any interface.

Re: Archicad AI Pilot— MEPbridge ACAIstr | Version v0.1.3 Release, Read/Write & Automation Valid

Bleufeng — Sun, 23 Aug 2026 05:26:55 GMT

v0.1.3 -Changed

Fixed

Slab, Roof, and Zone creation now accepts closed polygon contours.
Zone creation now uses the supplied contour and correctly writes the zone name
and category.
Explicit slab thickness is now applied correctly.
Degenerate polygon input now returns a clear validation error.
Copying Mesh and Morph elements is now supported.
MCP client status now uses the initialize handshake and distinguishes
connected clients from configured clients.
Public CI now exports only the approved command-safety test from the private
test directory.

Added

Added a read-only endpoint for listing running Archicad instances and their
open projects.

v0.1.4 -Changed

Fixed

- Explicit wall heights are no longer clamped to the story height.
- Walls now use the center reference line; the body no longer shifts sideways.
- Window sill height is applied; openings above the host wall top are rejected.
- Windows and doors inherit the host wall's story.
- `set_active_story` previews by default and reports `previousStoryIndex`.
- Stair tread depth is reported as the effective `resolvedGoing`.
- Workbench template replay refreshes saved templates before execution.
- Fixed bug causing slow reproduction of user‑defined templates in Workbench.

Added

- Moving and editing building elements by GUID with per-field masks and readback.
- Optional absolute-Z placement for walls, columns, objects, and lamps.
- Mirror and rotate accept explicit GUID lists.
- Four local server tools: list Archicad instances, capture/compare/replay snapshots.
- Copy is all-or-nothing with a single undo; delete is capped at 200 per call with `acknowledgeCount` above 50.

Re: Archicad AI Pilot— MEPbridge ACAIstr | Version v0.1.5 Release, Read/Write & Automation Valid

Bleufeng — Mon, 14 Sep 2026 00:54:42 GMT

v0.1.5 -Changed

Fixed

Roof geometry readback returns the full closed contour in model coordinates, fixing shifted or incomplete outlines in comparison and copy workflows.
Stair rule prechecks use a 1 mm tolerance for riser height, going, and 2R+G, preventing valid native stairs from being rejected by rounding noise.

Added

Field-level editing for Column, Beam, and Slab, with precise field masks and readback.
Controlled vector and two-direction array multiplication for Wall, Column, Beam, Slab, Roof, Mesh, and Morph by explicit GUID.
Read-only inventories for nine attribute families and native documentation element types.
Minimal native Text, linear Dimension, and single-line Label creation.
Story setting changes and guarded story deletion with full story snapshot verification.
First supported trim round: one Wall with one Roof operator using KeepInside or KeepOutside.
First supported solid-operation round: two Morph elements using Subtract or Add.
Dual-instance targeting keeps reads and writes bound to the selected Archicad instance and fails closed on invalid or dead target ports.

v0.1.6 -Changed

fix and capability release: rebuilt AC28/AC29 Add-Ons, corrected element move and roof geometry handling, and added create-with-properties, beam vertical placement, wall constraint and reference-line control, movable roofs, and clearer readback diagnostics across the Workbench Server and MCP tools.
