Lesson tool
3D models in a lesson
Rotate the model, zoom, switch between frontal/lateral projections or instructor-saved angles. Instructor mode lets you add arrow labels and save custom views — the config exports to JSON for embedding into a lesson. Below is a synthetic demo model; you can open your own STL/OBJ (processed only in the browser).
