About the app

What is SolidCraft?

SolidCraft is a free, open-source parametric 3D CAD application written in Rust. You sketch, constrain and build solids on a parametric feature timeline: change a dimension and the model rebuilds. It runs on Windows, macOS, Linux and in the browser, and AI agents can model through its built-in MCP server.

Its author describes it as early but usable for simple parts: 75 of 76 public reference parts match their analytic or FreeCAD-computed volume, area, centre of mass and bounding box. Its desktop installers are not code-signed yet.

SolidCraft is an independent community project by bherbruck and the SolidCraft contributors — not made by the ArtCraft team. We host it next to the Crafting Apps because it is built the same way: in Rust, open source and runnable in the browser.

SolidCraft features

Parametric CAD, built from scratch in Rust

Sketches and constraints in SolidCraft

Sketches and constraints

Lines, arcs, splines, slots and text on any plane, with dimensions and constraints solved by its own solver.

A parametric timeline in SolidCraft

A parametric timeline

Extrude, revolve, sweep, loft, fillet, shell, holes, threads and patterns — edit any step and it rebuilds.

Get started

How to use SolidCraft online

  1. 1

    Let it load once

    The first visit downloads SolidCraft (about 12 MB). After that your browser keeps it, so it opens in a moment.

  2. 2

    Start from a sample or a sketch

    Open one of the sample parts, or start a new design and sketch on a plane with dimensions and constraints.

  3. 3

    Build, then export

    Extrude, revolve, fillet and shell on the timeline, then export STEP, STL, 3MF or OBJ to your computer.

SolidCraft FAQ

Is SolidCraft free?

Yes. SolidCraft is free, open-source software (MIT or Apache-2.0), and this page lets you use its web version without paying, installing anything or creating an account.

Who makes SolidCraft? Is it an ArtCraft app?

SolidCraft is an independent community project by bherbruck and its contributors (github.com/bherbruck/solidcraft). It is not made by the ArtCraft team; we host it next to the Crafting Apps because it is built the same way.

Which file formats does SolidCraft support?

Its own .solidcraft designs; STEP (AP203/AP214/AP242) and IGES import and export; 3MF, STL and OBJ for 3D printing; and URDF for robot simulators.

Is SolidCraft good enough for real parts?

Its author calls it early but usable for simple parts, and checks it against reference parts computed analytically or with FreeCAD. For complex production work, test it first.

Why does my computer warn me about the installer?

The desktop builds are not code-signed yet. On Windows choose More info, then Run anyway; on macOS right-click SolidCraft in Applications and choose Open the first time.

Is this the official SolidCraft website?

No. The official site is bherbruck.github.io/solidcraft. This is an independent page that hosts the unmodified official web build (without its offline service worker).
