Go through the essential exercises of TDA one more time, so we are ready to tackle the complex exercises presented here

Three complex planar changes exercises: a volume made out of seven cubes in equilibrium, three tetrahedra and a sphere, three cubes and a sphere

Third possible variation of cubes intersections, in this case between a cube and hexagonal pyramid

Two cubes intersections, pyramid and prism intersection, two prisms intersection with common volume

Complex sections and planar changes (these exercises will blow your mind)

Advanced cast shadows to take your understanding of how constructed shadows work to the next level (in both triple projection and isometric axo)

Complex roofing exercises – random angles roofing, different heights roofing and wall roofing (a massive upgrade from simple roofing exercises)

Complex intersections and volume unwrapping for hexagonal prism, sectioned hexagonal pyramid and cube intersection (this is the most complex descriptive geometry I have personally come across)

Icosahedron and dodecahedron intersections (more variations from the standard positions)

Short recap of the essentials of technical drawing.

Intermediate exercises to develop key technical problem solving skills with intermediate exercises that feature cubes, tetrahedra and spheres.

Spheres tangency problems that will teach you everything you need to know about sphere tangencies.

2d problem solving exercises to get your smarter in understanding basic planar geometric constructions.

Ultimate guide to hexagonal and pentagonal pyramid and volumes.

Develope ultimate spatial vision with cube sections and planar change exercises (over 8 exercises in triple projection, volume unwrapping and isometric axonometric).

How to draw and design a complex roofing system.

Six exercises with dodecahedra and icosahedra – this will expand your understanding of technical drawing even further.
