Structure Synth — The Complete Guide: 3D Structures From Recursive Rules
Structure Synth creates 3D geometry from a small set of recursive rules, written in a compact language called EisenScript, rather than by modelling by hand. One rule such as “box, move, rotate, scale down — and repeat” produces a complex structure, and every change to the rule produces a new variation.
Structure Synth
Structure Synth Project
Generates 3D structures from a short rule script, in the spirit of generative design.

- A compact rule language — primitives, transformations and repetition.
- Controlled randomness — weighted alternative rules for variations.
- Instant preview — the structure is rebuilt with every script change.
- Export — OBJ and templates for external renderers.
- Three operating systems — Windows, macOS and Linux.
Who it suits, and the limitation
Architecture students and engineers who want to explore lattices, repeating patterns and facades generatively, or to create geometry for form studies. It is not a design tool: there are no engineering dimensions and no analysis. The project is no longer under active development and the last release is old — treat it as final.
