Overview

Hello HN users,

This is a CAD‑by‑code project I have been working on in my free time for more than a year.

Goals

The project was built with three main goals in mind:

1. Familiarity – It should feel like other CAD programs, using the same workflow and terminology.
2. Reduced mental effort – Achieved by:
   • Providing live rendering and visual guidance as you type.
   • Allowing the user to reference existing edges/faces in the scene instead of calculating everything manually.
   • Offering interactive mouse helpers for features that are hard to write by code. Currently there are three interactive modes:
     • Edge trimming
     • Sketch region extrude
     • Bézier curve drawing
   • Implicit coding whenever possible, e.g., sensible defaults for most parameters and automatic fusion of intersecting objects so you don’t have to manage object merging yourself.

Current State

I believe these goals have been met to a good extent. The program is still in early stages, with many features to add and rewrite, but it is already usable for simple models.
