For teachers

This tool is free and built so any technical drawing teacher can use it with their students without installing anything. Every exercise opens in 3D and the solved steps are shown with the drawing already built.

What it covers

• The high-school syllabus: lines, intersections, distances, parallelism, rotations, angles and spins.
• Step-by-step solved exercises.
• Academy with the theory ordered by topic.
• Real-time 3D: students rotate the solid while you explain.

Nothing to install

Everything runs in the browser, on a laptop, phone or tablet, and keeps working offline once loaded.
