Edizioni Glyphe · second edition, September 2026

The built-in help tells you what a component does. It does not tell you when you need it, nor what goes wrong: those are the two things you learn by making mistakes, and they are what this book puts in writing. One hundred and twenty-three components chosen from the thousand available because these are the ones actually used, each given half a page: the capsule as it appears on the canvas and, beside it, a drawing of what it produces.

The book opens with a building constructed in full: a tower of rotated floors born from four numbers — plan width, number of floors, floor-to-floor height, twist. Change one and everything redraws, dimensions, envelope, floor slabs and bill of quantities included. The definition is set out across a full page and can be rebuilt without having the file.

Inside the book
  • 123 components in nine families: curves, vectors and planes, surfaces, lists and data trees, transformations, numbers and domains, polylines, intersections, preview
  • For each one: what it does, when you need it and what goes wrong
  • An applied case study for each family and a closing design exercise
  • The definition of a building with rotated floors, across a full page
  • English-Italian glossary, index of components, analytical index
  • Over 120 vector plates drawn for the book
