About the book
Three flat views, one solid. Learn to read top, front and side views, rebuild the shape in your mind and draw it on an isometric grid: 120 puzzles with step-by-step lessons.
THINK IN 3D teaches you to read orthographic views (top, front and side), picture the solid they describe, and sketch it on isometric grid paper. It is the core skill behind engineering drawing, architecture, CAD and product design, turned into screen-free puzzles.
Five illustrated lessons and a worked example start from zero. The puzzles then climb through four levels, Warm-up, Builder, Architect and Master, with slopes introduced one at a time.
Who it’s for
Teens 12 and up and adults who like logic puzzles, students starting technical drawing or CAD, and anyone practising for the spatial reasoning sections of aptitude tests.
