ArchBench – Control Blender through chat

ArchBench launched as a desktop AI assistant that controls Blender through chat, letting users describe a modeling change, review the proposed action and affected objects, then apply it in the native application with supported Undo. The tool's first integration was demonstrated on macOS with live scene context, and broader release testing is underway; free accounts start with GPT-5.6 Luna while GPT-6 Astra is the paid default reasoning model. Public MCP connectors on GitHub are planned starting with Blender, and ArchBench's IFC modeling and reformatting workflows for architecture, engineering and construction remain in design.

Describe what needs to change. Start from live scene context. Describe a blockout, an arrangement, or a change to your selection. Free accounts start with GPT-5.6 Luna; GPT-6 Astra is the paid default. YOUR AI ASSISTANT FOR 3D DESIGN A desktop companion for your design software. Describe an idea, review the proposed changes, and keep creating in your model. Starting with Blender. Your design tools. An assistant alongside. YOUR SOFTWARE. A NEW WAY TO WORK. Stay in the tools you know. Choose an application to see where its connector stands. Our first integration. Live scene context, reviewed modeling actions, and native Undo have been demonstrated on macOS. Broader release testing is underway. Public MCP connectors on GitHub are planned, starting with Blender. Each will document its supported versions and workflows. BUILT AROUND THE MODELING WORK Start with a clear instruction. Keep the project context close. Produce a result you can keep working with. Plans, material schedules, and specifications are next. Planned IFC workflows will connect project information to building elements, with units and properties checked. Review the proposed operation and affected objects. ArchBench applies supported changes in the native application and reads back the result. FROM INTENT TO EDITABLE WORK A desktop workflow that keeps you close to the design, from the first request to the final decision. Pick an enabled AI model and connect a supported design application. Start with the live model. File and design-data inputs are coming next. Ask in your own words. Inspect the proposed action and the objects it affects. Approve the action, inspect the native result, and use supported Undo when needed. AI WORKFLOWS FOR ARCHITECTURE, ENGINEERING & CONSTRUCTION We’re designing ArchBench to turn conversations into structured modeling, revision, and data preparation workflows. Our mission graphs guide the task; IFC gives building information a shared structure; native connectors carry out supported changes. Carry the brief, decisions, and progress through a defined workflow. Resolve missing inputs, review the proposal, and continue from the right step when the conversation resumes. Work with building elements, properties, units, and relationships. Design modeling and reformatting tasks around explicit schema mappings and checks. Connect reviewed changes to supported operations in your design software. Read back the result and retain the evidence needed for the next step. The workflow we’re designing Astra provides general reasoning and tool-calling capabilities. ArchBench’s intended value is the AEC workflow system around the model: mission state, building-data mappings, native operations, and result checks, brought together for everyday project work. GPT-6 Astra is the default reasoning model within that system. No. IFC provides a common schema for building information. Each workflow still needs a supported schema version, explicit source-to-target mappings, and checks for missing or unsupported information. Native editing history and application-specific features may not transfer. ArchBench’s IFC modeling and reformatting workflows are in design. About the IFC schema https://technical.buildingsmart.org/standards/ifc/ AEC harness architecture in development. Mission graphs exist in our chat platform; their use for desktop AEC tasks and the IFC layer are planned. GPT-6 Astra is the default model; live availability depends on account and release access. GPT-6 ASTRA · ARCHBENCH GPT-6 Astra is the default. ArchBench brings your project context, modeling tools, and change review into the conversation. Live access depends on your account and release. YOU STAY IN THE DESIGNER’S SEAT Working with a real project means knowing what will change, where it will happen, and how to get back. ArchBench Inspect the proposed action and affected objects before you approve. Results stay in the connected application as native model work. Native Undo and recovery are qualified for each supported workflow. ArchBench is a desktop AI assistant for 3D modeling and building design. It brings live model context into a conversation so you can describe and review changes in your design software. Blender is the first integration under development; guided AEC workflows and IFC building-data support are planned. Free accounts start with GPT-5.6 Luna. GPT-6 Astra is ArchBench’s default model for paid accounts. You can choose another eligible model independently of your design software. Live access depends on your account and the current release. IFC-aware AEC mission workflows are still in development. Blender is the first integration under development. SketchUp, Rhino/Grasshopper, Revit, and Archicad are planned, with more connectors to follow. Support will be released for specific workflows and application versions. Public MCP connectors are planned, starting with Blender. The aim is to let compatible AI assistants connect to supported modeling software, with setup instructions and a clear list of supported actions and versions. Public repositories and installation links will appear here when published. File-backed commands are on the roadmap, beginning with selected images, text briefs, and bounded PDF workflows. Structured schedules and connected design data follow. The current Blender foundation uses live scene and viewport context.
