Engineering guides
The math, the architecture, and the security model behind connecting an AI assistant to real CAD work — explained once, at real depth, instead of repeated shallow on every product page.
Geometric tolerancing
GD&T Computation Explained
Bonus tolerance, virtual condition, resultant condition, and worst-case vs. RSS stack-up — the ASME Y14.5-2018 math, mapped to six real tools.
Integration architecture
MCP vs. Direct CAD APIs
Why a shared protocol beats a bespoke integration per AI client, per CAD vendor — the actual math on what each approach costs to build and maintain.
Desktop connectors
Local Bridge Architecture
What runs on your machine, what a device activation actually grants, and why only the answer your AI asked for ever leaves it.
Security & trust
CAD AI Security
Your CAD models and BOMs are your IP, not generic data. A checklist for what to verify before connecting an assistant to a CAD environment.
How automated edits work
Parametric CAD Automation
Driving a named parameter and rebuilding is a different, contained kind of edit than regenerating geometry. Here's why that distinction matters.
Worked examples
CAD Automation Examples
Six real, shipped workflows — GD&T review, tolerance stack-up, sheet-metal export, mass properties, parametric edits, neutral-file export.
Trust & guardrails
Engineering-Agent Safety
Typed tools, nothing saved without you, the undo stack, and an audit trail — what actually bounds an AI-driven CAD edit.
