How natural language interaction is changing the way engineers explore and validate design data
Autodesk Inventor 2027 introduces an early preview of a new way to interact with CAD models—one where you can query and explore design data using natural language.
With the Autodesk Assistant (Technical Preview), users can move beyond traditional workflows that rely on navigating the model browser, inspecting properties, or writing custom rules. Instead, you can ask questions such as:
- “What are the heaviest components in this assembly?”
- “Which parts are missing material assignments?”
- “Show the structure of this assembly”
and receive answers based on the actual model data currently open in Inventor.
While still in preview and primarily focused on data exploration and analysis, the Assistant provides a practical first step toward more interactive workflows.
This represents a shift in how design data is accessed and understood:
👉 from manually navigating and inspecting models
👉 to interacting with design data through questions
Autodesk Assistant (Technical Preview)
At Autodesk University, Autodesk demonstrated how AI could transform design workflows by enabling natural language interaction with CAD data.
Inventor 2027 introduces an early implementation of this vision as a technical preview.
Autodesk Assistant allows users to:
- Query design data
- Analyze models
- Navigate complex assemblies
- Support design review workflows
How to Access Autodesk Assistant
Autodesk Assistant is available in Inventor 2027 as a technical preview. For setup steps and availability details, refer to the official Autodesk Help documentation.
About Autodesk Assistant in Inventor
How Autodesk Assistant Understands Your Model
Autodesk Assistant can access the active design model directly, allowing it to return responses grounded in actual geometry, structure, and properties.
This is different from general-purpose AI systems, which rely only on text input rather than real model data.
Behind the scenes, this capability is enabled by the Model Context Protocol (MCP), which provides structured access to the current model.
Core Capability: Model Information Retrieval
A primary use case is retrieving structured model information.
Example:
“List all components in the assembly with hierarchy, including weight and volume.”
The Assistant:
- Analyzes the assembly structure
- Extracts iProperties
- Returns organized results
Previously, this required:
- iLogic
- VBA
- Custom add-ins
Now, instead of navigating to find information, the interaction becomes:
👉 Ask a question and receive a structured answer
Using the Assistant to Review Your Designs
This capability extends naturally into design validation workflows.
Example:
“List parts with no material assigned or zero density.”
Instead of manually checking properties or writing rules, users can:
- Define conditions in natural language
- Identify issues more efficiently
This introduces a new workflow:
👉 Using conversational queries to validate design quality
These queries can also be used as on-demand checks to surface potential issues in the model—effectively allowing users to “ask for” conditions that would otherwise require custom validation rules or scripts.
This suggests a shift from design review as a downstream task to something that can be performed interactively during the design process.
Example Prompts
The following examples illustrate how Autodesk Assistant can be used.
As this is a technical preview, some requests may result in guidance or step-by-step instructions rather than fully automated execution.
Structure Understanding
- “Describe the assembly structure as a tree”
Information Retrieval
- “List weight and volume of all components”
Analysis
- “Show the top 5 heaviest components”
Design Quality Check
- “List parts with missing material”
- “Find components with extremely small volume”
- “Identify components that may require attention based on missing or inconsistent properties”
Workflow Shift
Traditional workflow:
- Open model
- Inspect the browser
- Check properties
- Then modify
With Autodesk Assistant:
Instead of interacting with the model to understand it, users can first understand the model through conversation—and then proceed with operations.
👉 From explore by clicking → to understand by asking
This is particularly valuable for:
- Large assemblies
- Unfamiliar datasets
- Faster onboarding
Current Limitations
As a technical preview, Autodesk Assistant currently focuses on:
- Information retrieval
- Analysis
- Navigation support
It can help answer queries such as:
- “Explain the structure”
- “Find heavy components”
- “List problematic parts”
However, for model editing operations such as:
- “Add a fillet”
- “Create a sketch and extrude”
- “Change this dimension”
It currently provides:
- Guidance
- Step-by-step instructions
but does not yet execute them automatically.
👉 Autodesk Assistant does not yet create or modify geometry directly, and instead focuses on understanding, analysis, and guidance based on design data.
This means there is a clear distinction today:
👉 Retrieving and analyzing model data is supported, while editing operations remain guided rather than automated.
Why This Matters for Developers
While this preview is primarily aimed at helping users explore and understand model data, it is also relevant from a developer perspective.
Many information-retrieval workflows in Inventor have traditionally required iLogic rules, VBA scripts, or custom add-ins. Autodesk Assistant suggests that some of these interactions may increasingly be handled through natural language instead.
At the same time, custom workflows, validation logic, integrations, and editing automation still remain areas where developers can provide significant value. In that sense, the Assistant may not remove the need for development, but it may begin to shift where developer effort is most useful.
Future Direction
The foundation is already in place:
- Direct model access
- Integration with Inventor APIs
- Context-aware intelligence
Future capabilities may include:
- Executing modeling operations
- Optimization suggestions
- Multi-step automation workflows
Example future interactions:
- “Add fillets to these edges”
- “Suggest weight reduction strategies”
- “Update materials and recalculate properties”
Summary
The Autodesk Assistant technical preview in Inventor 2027 enables:
- Natural language access to design data
- Immediate model insight
- Conversational design review
- On-demand identification of potential issues
This represents a shift:
👉 From command-based CAD
👉 To intent-driven, conversational design
While still evolving, this preview represents an early step toward more interactive and AI-assisted design workflows.
