What is Hestus?
Hestus is an AI-powered CAD copilot that integrates directly into Autodesk Fusion 360 to accelerate sketching and parametric design work. The tool, called Sketch Helper, recognizes designer intent and offers one-keystroke suggestions for constraints, symmetry axes, mirroring, and circle alignment without forcing users to type prompts or leave their CAD environment. Hestus is a Y Combinator-backed company (S24) that raised $1.5M in seed funding to build AI tooling specifically for hardware engineers.
Unlike text-to-CAD generators that try to produce models from scratch, Hestus operates as an autocomplete layer on top of an existing CAD workflow. The product is currently in beta with a free download for Fusion 360 users, and the company has signaled plans to expand support to additional CAD platforms over time.
What Are Hestus’s Key Features?
Intent Recognition Suggestions
Hestus continuously analyzes the geometry you are sketching and predicts likely next moves like equality constraints between similar circles, tangents between lines and curves, or anchoring loose points to the origin. Each suggestion is surfaced inline so you can accept it with a single keystroke. This collapses repetitive constraint work that otherwise takes dozens of clicks per sketch.
Symmetry and Mirror Detection
The tool automatically detects existing lines of symmetry in your sketch and proposes mirror axes when none exist. It can identify candidates for chain mirroring so complex geometry can be reflected across an axis in one click. This is especially useful for parts with bilateral or radial symmetry where manual mirroring is error-prone.
HV Circles Alignment
A dedicated recommendation aligns multiple circles horizontally and vertically across a sketch instantly. Instead of placing dimensional constraints between every pair of circles, Hestus reads spatial intent and applies the alignment in one action. This keeps hole patterns clean and parametric without manual setup.
Native Fusion 360 Integration
Hestus runs as an Autodesk App Store plugin that lives inside Fusion 360 rather than as an external tool. There is no chat window, no separate app to switch to, and no copy-paste between environments. Designers stay in the toolbar and shortcuts they already know while AI suggestions appear in context.
Point and Curve Connection Helper
Sketch Helper scans for dangling points and proposes connections to nearby curves, other points in a chain, or directly to the origin. This anchors sketches properly so they stay fully constrained as parameters change. It cuts out the tedious detective work of finding which point is making a sketch under-defined.
Free Beta Access
The Sketch Helper plugin is currently free for Fusion 360 users while Hestus collects feedback during its beta period. The team explicitly invites early users to join a priority list for upcoming features and cross-platform support. Hardware engineers can install it from the Autodesk App Store in minutes without sales calls.

Pros and Cons
Pros
- Sketch Helper is genuinely free during the beta period with no credit card or trial expiration, which is rare for AI-powered design tooling.
- Native integration into Fusion 360 means there is no context switching, no prompt typing, and no learning curve for engineers already familiar with the CAD environment.
- One-keystroke acceptance of suggestions is significantly faster than clicking through standard Fusion 360 constraint menus for routine sketch tasks.
- Backed by Y Combinator and $1.5M in seed funding, so the company has runway to keep iterating rather than vanishing after a few months.
- Symmetry detection and chain mirroring features address real pain points in parametric design that no other Fusion plugin currently solves with AI.
Cons
- Currently only supports Autodesk Fusion 360, leaving SolidWorks, Onshape, NX, and Creo users without access to the tool.
- The product is still in beta, which means feature stability and long-term roadmap commitments are still being defined.
- No public pricing means companies cannot budget for adoption beyond the free tier or know what production access will cost later.
- AI suggestions work best on routine 2D sketch operations and offer less value for complex 3D modeling, surfacing, or simulation workflows.
- Sketch Helper requires installation through the Autodesk App Store and active CAD use to evaluate, so casual evaluators cannot demo it from the marketing page alone.

Skip Hestus if: you need a battle-tested tool with a large community.
Best Hestus Alternatives
| Tool | What It Does | Price |
|---|---|---|
| Autodesk Fusion 360 native AI | Autodesk’s own AI features built directly into Fusion offer generative design and topology optimization, but lack the inline sketch autocomplete that Hestus focuses on. | Included with Fusion 360 from $85/month |
| Onshape | A cloud-native CAD platform with collaboration features and an extensible app ecosystem, though it requires migrating off Fusion entirely rather than augmenting it. | Free for hobbyists, paid plans from $1,500/year |
| Zoo (formerly KittyCAD) | A text-to-CAD startup building APIs and tools that let developers and designers describe geometry and have AI generate it, taking a more generative approach than Hestus’s autocomplete model. | Free tier with usage-based pricing |
Final Verdict: Is Hestus Worth It?
Hestus is a smart, narrowly-scoped AI tool that solves a real ergonomic problem in CAD sketching: too many clicks for too little design progress. The free beta means there is essentially zero downside for Fusion 360 users to try it, and the symmetry and circle alignment features alone can save meaningful time on parts with repetitive geometry.
The main caveats are platform lock-in to Fusion 360 and the lack of clarity on future pricing. If you live in another CAD tool or work primarily on assemblies and surfacing rather than sketches, Hestus will not change your day yet. But for solo hardware engineers and small product teams using Fusion, it is one of the more useful free downloads available right now.
FAQ
Does Hestus work with SolidWorks or Onshape?
Not yet. Hestus currently only supports Autodesk Fusion 360 through the Sketch Helper plugin available on the Autodesk App Store. The team has indicated plans to expand to other CAD platforms but has not announced specific timelines or which tools will be supported next.
How much does Hestus cost?
Sketch Helper is free during the beta period with no time limit currently announced. Hestus has not publicly disclosed pricing for future paid features or enterprise plans, so existing users get the full plugin experience without paying. Contact the founders directly for any enterprise or early-access conversations.
Will Hestus modify my CAD files without permission?
No. Every Hestus suggestion is shown inline and only applied when you accept it, usually with a keystroke. The plugin does not silently change parametric constraints, geometry, or part history, so designers retain full oversight of their files at all times.
Does Hestus require an internet connection?
Yes. Sketch Helper communicates with Hestus’s AI services to generate suggestions, so an active internet connection is required while the plugin is in use. The team has not announced any offline or on-premises mode for sensitive design environments.
Is Hestus suitable for production hardware design?
Yes for sketch and constraint work, with caveats. The product is in beta, so teams working on regulated or safety-critical hardware should evaluate it carefully and confirm internal IP and security policies before adoption. Hobbyists, indie hardware builders, and small engineering teams have less risk in trying it broadly.
Can Hestus generate 3D models from text prompts?
No. Hestus is not a generative text-to-CAD tool. It is an autocomplete and intent-recognition layer that operates on sketches you are already drawing in Fusion 360, suggesting next steps rather than producing entire models from scratch.
