AI design-review agents for CAD assemblies
Quatrion turns complex CAD assemblies into a spatial reasoning layer that engineering teams can query for tolerance, manufacturability, simulation triage, ergonomics, safety, and design-review risks — with evidence tied back to geometry.
Built for CAD-heavy engineering teams where design reviews, simulation handoffs, and manufacturability checks still take days.
Engineering review is still trapped in tool handoffs
CAD, FEA, tolerance analysis, manufacturability checks, and compliance reviews often live in separate workflows. Every new question can mean another export, another mesh, another manual review, and another delay.
Hours to days of preprocessing, handoffs, screenshots, and manual engineering review.
Encode the assembly once. Run multiple design-review agents against the same spatial representation.
Four surfaces. One workbench.
The shell every agent renders into — and the deployment model that lets your team run it inside your network boundary, against your own files.
Cloud-agnostic by design. No managed-runtime lock-in.
A polyrepo of independently deployable services behind a single workbench. Storage, secrets, identity, and job state are abstracted; nothing on the critical path requires a specific cloud provider.
Between your CAD stack and the decisions that come out of it.
Quatrion does not replace CATIA, NX, SolidWorks, Ansys, Abaqus, PLM systems, or engineering judgment. It adds a geometry-aware reasoning layer that helps teams triage issues earlier, preserve evidence, and accelerate review workflows.

- Design-review findings with provenance
- FEA prioritization & cycle triage
- Manufacturing & DFM signals
- Standards-referenced analysis runs
Evidence, not opinions. Tied back to geometry.
Every finding the workbench returns carries its provenance — so a result can be reviewed, replayed, and trusted, not just read.
Replayable reasoning
Every run is captured so it can be replayed, shared, or compared to a prior run.
Geometry-linked evidence
Findings point back at the specific geometry references behind them.
Engineering audit trail
Inputs, tool chain, and outputs are recorded as structural provenance.
Design-review agents for real engineering workflows.
Grouped by the engineering decision they support — not by algorithm. Each group runs against the same encoded assembly, and your team can author more through the SDK without rebuilding the encoding, routing, or evidence layers.
Design review
Catch geometric and assembly-level issues before they reach a release gate.
- Tolerance verification
- Surface continuity
- Part consolidation
- Clearance checks
Simulation triage
Decide which parts and load cases deserve a full solver run first.
- NVH screening
- Buckling susceptibility
- Stamping / forming risk
- CoG migration
Ergonomics & safety
Screen occupant and operator interactions against standard envelopes early.
- Reach envelope
- Vision obstruction
- Head-impact zones
- Human access constraints
Reference agents demonstrated on the encoded benchmark assembly. They are the patterns your designers extend from via the SDK.
One assembly, encoded once — queried by every agent.
In a 1,492-part automotive body assembly, Quatrion encodes the geometry once into a compact query cache, then runs every first-pass agent against the same spatial representation — no re-meshing per question.
Benchmark figures from a representative 1,492-part automotive body assembly. Intended for first-pass design-review triage — not a replacement for final engineering validation.
Read benchmark notes →Encode once. Query repeatedly.
Quatrion compiles a CAD assembly into a compact, queryable spatial layer before any solver touches it — every agent then inspects geometry, tolerances, surfaces, and clearances without starting from scratch each time. The math below is the public face; schemas, encoders, and benchmarks stay IP-protected.
CAD becomes a compact geometry substrate.
Each part is encoded as integer-quantized position, orientation, and a shape descriptor. A 100–500 MB assembly collapses to a 1–5 MB cache that downstream agents and tools query directly — no re-meshing per question.
Shape behavior is captured as compact screening features.
For each surface, Quatrion computes geometry-derived screening features that help prioritize NVH, stiffness, and thermal-risk review before a full material-aware solver run. These features are intended for first-pass triage, not replacement of material-aware simulation.
Fit and tolerance risk is prioritized for review.
Mates, contacts, alignments, and clearance targets are organized into reviewable relationships so fit drift can be ranked by practical engineering impact. The goal is to surface systematic tolerance issues clearly, instead of asking an engineer to inspect thousands of part-pair distances.
And three pieces of authoring, that your designers own.
Reference agents on this page were authored against the same SDK your team will use. You define what the agent answers, what geometry it reads, and what evidence it returns — the workbench renders the rest.
Bring models straight from your source of truth.
Many engineering models never arrive as a local upload — they live inside cloud CAD, PDM vaults, and enterprise PLM. Connectors pull a selected revision or configuration directly into Quatrion as a derived model for viewing and spatial reasoning, while preserving the source item, revision, and BOM path behind every finding.
Provenance, not detached geometry
Every import carries a visible source summary — system, revision, configuration, and BOM path.
A derived model, clearly labeled
Imports open in the same viewer, runs, and evidence surfaces — labeled derived, not the authoritative file.
Credentials stay on the boundary
Connections reference credential profiles, never raw tokens, signed URLs, or source files.
Honest failure, not silent fallback
An unsupported source returns a typed, actionable blocker — never a silent mesh or fabricated claim.
Connectors are read-only in v1. They import a selected revision as a derived model for review — they never check out, modify, or write back to your source system, and the source item/revision stays the authoritative CAD record.
Logos identify the source systems Quatrion connects to or plans to support, and reflect roadmap status, not availability. They do not imply affiliation, endorsement, or partnership — each mark is the property of its owner.
Built by engineering and infrastructure operators
Quatrion is being built by operators with experience across cloud infrastructure, data platforms, AI systems, manufacturing workflows, and enterprise engineering environments.
The company is focused on one clear wedge: helping CAD-heavy engineering teams run first-pass design-review agents over complex assemblies, with evidence tied back to geometry.
Bring one assembly. Run one agent. See the evidence.
Start with a CAD assembly and one high-value review workflow. Quatrion will show how spatial agents can accelerate first-pass engineering triage while preserving evidence and provenance.
