Describe what you need in plain language — NexusAI runs a complete agentic loop inside your model: inspect data, search the Revit API, execute Python automation, review enriched execution results, and self-correct until the task is done. Twelve AI models. Seven years of Revit. One installer.
Watch the agentic loop in action — live reasoning, API search, script execution, and enriched result verification streamed in real time as NexusAI completes complex Revit tasks end to end
Two-story house built end to end by NexusAI's agentic loop
NexusAI doesn't stop at suggestions. It runs a closed-loop workflow that plans, acts, verifies, and retries — delivering finished Revit work, not just advice.
One request triggers an autonomous multi-step workflow: collect model data, search the Revit API, execute Python automation, return enriched execution results, evaluate outcomes, and retry with targeted code edits until the task succeeds.
One installer covers seven years of Revit — from legacy 2021 projects to the latest 2027 release. NexusAI adapts API calls to your installed version automatically, so your whole firm stays productive regardless of which Revit year they're on.
Before complex automations, NexusAI semantically searches the Revit SDK index to find correct method signatures, parameters, and overloads — avoiding trial-and-error script failures on walls, floors, roofs, structural, MEP, hosted families, and version-sensitive APIs.
After every model-changing script, NexusAI returns a structured change report — element categories, types, levels, hosts, worksets, and MEP connectivity — so the agentic loop can verify outcomes from data and iterate with refined code without manual checking.
Watch every phase in real time — AI reasoning, API lookups, script execution, and enriched result evaluation stream into a transparent workflow panel so you always know what NexusAI is doing.
Claude Opus 4.8, Claude Sonnet 4.6, GPT-5.5, GPT-5.4, GPT-5.3 Codex, Gemini 3.1 Pro, and six more — each with native function calling across the full agentic toolchain. Pick the model that fits your task and budget.
Understands your active document, Revit version, project type, units, phases, views, levels, worksets, and element counts in real time so every automation is tailored to your open model.
Process Excel, PDFs, Word documents, web APIs, and images inside the agentic loop. Import specifications, connect cost databases, and drive automations from real project data.
Pre-execution validation blocks unsafe operations. Scoped Revit transactions, automatic write detection, and cooperative stop let you halt the loop anytime while keeping your model protected.
Tools like Autodesk Assistant answer questions inside Revit. NexusAI completes the work — running a full agentic automation loop that inspects, executes, verifies, and iterates until your model is updated.

| Revit version coverage | Typically newest releases | 2021, 2022, 2023, 2024, 2025, 2026, 2027 |
| AI model choice | Single vendor | 12 models across Claude, GPT, Gemini & Grok |
| External data (Excel, PDF, APIs) | Limited | Full Python data integration |
| Enterprise SSO & seat management | Varies | Azure AD, audit logging, machine binding |
You describe the outcome. NexusAI handles the rest — autonomously, inside Revit.
One ribbon button opens NexusAI and connects to your Revit session via a local Python execution service. Live context — version, views, levels, worksets — flows in automatically.
"Build a two-story starter house," "Generate an electrical one-line," or "Import this Excel sheet into rooms" — state what you need, not how to code it.
NexusAI inspects your model, searches the Revit API for correct signatures, and plans the automation — streaming its reasoning and API lookups so you see every decision.
Python scripts run directly in your open model with scoped transactions and safety validation. Read-only data collection and write automations are handled as separate, purpose-built steps.
After model changes, NexusAI attaches enriched execution results — structured change reports of what was created, modified, or deleted — evaluates the outcome, and retries with targeted code edits if needed — looping until the task is complete.
