Frequently Asked Questions
What is an Engineering Learning Studio?
An Engineering Learning Studio is a free, discipline-specific hub that combines design tools, interactive 3D web apps, technical reference articles, downloadable guides, and links to companion iOS apps — all in one place. Studios are organized by engineering discipline so you can go deep on one specialty.
Are the Learning Studios free to use?
The studio web apps and tools are free for registered users (free account required). The core design tools and 3D viewers are accessible at no cost. Companion iOS apps are available separately on the App Store.
Which studios currently have live tools?
The Electrical, HVAC, Fire Alarm, and Enterprise IT Studios currently have live interactive tools. The Electrical Studio features a full 3D residential wiring viewer and NEC design tools. New studios and features are being added regularly.
What technology powers the 3D viewers?
All 3D viewers are built with Three.js (WebGL) and run directly in your browser — no plugins or downloads required. They support orbit controls, click-to-inspect device info, system filtering, floor filtering, and include an integrated Learning Hub with quiz, glossary, guided tours, and fault simulation.
