Common Code Tutorials

The core Bitbybit programming tutorials, covering the algorithms that work the same way in every editor and on every 3D engine. This is the material that carries across the whole platform: the base library of points, vectors, lines, lists, maths and text; the drawing layer that puts geometry on screen; and the Bitbybit OCCT Kernel that does real solid modelling with booleans, fillets, lofts and STEP export. Every page shows the same idea in Rete, Blockly and TypeScript, so you can start in whichever editor suits you and move between them later without relearning the concepts.

📄️Manifold

Manifold, Bitbybit's fast mesh kernel - solids that always stay closed, cross sections that extrude, revolve, loft and sweep, booleans in bulk, meshes, recipes, and moving shapes between OpenCascade and Manifold - with examples in Rete, Blockly and TypeScript and a table of every function.

📄️JSCAD

JSCAD, Bitbybit's polygon kernel for quick solids - primitives, flat polygons and paths, extrusions with a twist, hulls, booleans, expansions and stroke-font text - with examples in Rete, Blockly and TypeScript and a table of every function.

📄️Things

The catalogue of finished parametric models in bitbybit.things - vases, cups, a medal and a phone stand to 3D print, a laser-cut phone holder, tables, a chair, a house and two birdhouses - how to build, draw and dispose one, and which need a plan, with an example in Rete, Blockly and TypeScript.
