Showcases

Scripts larger than a tutorial, each built in Blockly and explained step by step on its own pages. Download a script and open it with More > Import in a Blockly editor, press Run The Code, then change its values and run again.

Drone

A quadcopter with every part a real one has: a carbon frame with hexagon vents, arms with cut-outs, motors with cooling slots, two-blade propellers that alternate their spin, bolts, lights, a canopy traced with a honeycomb and the bitbybit logo on its hatch, sprung landing legs, a GPS mast and a camera on its gimbal. Four variables size it; change the arms to six or eight and it rebuilds. Every part is a function, loops repeat parts around it and cut their holes, and async functions await the geometry they measure; the functions are collapsed, so the stacks that call them read like a list of parts.

How it is built, step by step over seven chapters.

Hexagon hive

A honeycomb of hollow hexagonal cells, each with outer walls and an inner cavity, each raised to its own height. A grid of hexagon wires gives the cells, OCCT makes faces from them and extrudes each one to a height of its own.

How it is built, in Rete, Blockly and TypeScript.

Advanced loft

A vessel-like form lofted through several wires of different sizes, with the loft's advanced options choosing how the surface runs between them.

Twisted polygon ornament

Hexagonal wires scaled and turned a little more at each level, then lofted into a twisted solid ready for 3D printing.
