SolidCraft Launches: A Free, Open-Source Parametric 3D CAD Built in Rust

SolidCraft is an open-source parametric 3D CAD application written in Rust, positioned as a free alternative to commercial tools like Autodesk Fusion. Its GitHub repository and SourceForge mirrors are the primary distribution channels, with current builds at v0.16.1.

The project matters for one reason: parametric CAD is one of the last categories where free options are genuinely thin. Fusion 360 moved to a subscription model, FreeCAD is capable but has a steep learning curve, and browser-based tools either cap their free tiers or lock exports behind paywalls. SolidCraft targets the gap with a native application, no license fee, and a codebase anyone can inspect.

What SolidCraft actually is

SolidCraft is a parametric modeling environment. You sketch on a plane, apply constraints, and build features that stay editable — the same workflow professionals use in SolidWorks or Fusion. “Parametric” is the key word: dimensions are not baked in, so changing a measurement later rebuilds the geometry instead of breaking it.

The Rust foundation is not incidental. Rust gives the application native performance without a runtime dependency, which matters when you are pushing complex assemblies around on screen. It also makes the codebase auditable, something that resonates with engineers who need to know what a tool is doing with their files.

Why it is getting attention now

Search interest jumped sharply in mid-October 2026, climbing roughly ninefold within thirty days. The trigger appears to be the v0.16.x release line reaching a usable state — the versions landing on SourceForge now include the sketch-and-constraint workflow that earlier builds lacked.

That release cadence is the signal worth watching. A CAD tool is only useful once it can complete a real design cycle, and the version history suggests SolidCraft is crossing that threshold rather than being a promising prototype.

How to get it

Source code. The canonical repository is on GitHub. Build from source if you want the latest commits, want to audit the code, or need to compile for a platform without a prebuilt binary.

Prebuilt binaries. SourceForge mirrors host versioned builds — v0.16.1 is the current stable line, with v0.15.0 still available. Downloading from the mirror is faster than building unless you specifically need unreleased changes.

Installation and first project. Setup steps, dependency requirements, and a walkthrough of building your first parametric part are covered in our dedicated guide — see how to install SolidCraft and model your first part.

What to check before committing

Two things decide whether SolidCraft fits your work right now.

First, file format support. If you need to open existing Fusion or SolidWorks files, verify import compatibility against your actual project files before assuming a clean handoff. Interoperability is where most open-source CAD tools lose people.

Second, the feature surface for your specific discipline. Parametric sketching and basic solids are in place; advanced surface modeling, sheet metal, and simulation are the areas where maturity varies most between open-source CAD projects. Match the tool against the work you actually do, not the feature list.

Frequently asked questions

Is SolidCraft really free? Yes. It is open source with no subscription, no export paywall, and no watermark on output.

Can it replace Autodesk Fusion for professional work? It depends on your workflow. For parametric part design and sketch-based modeling, it covers the core loop. For advanced surfacing, CAM, or simulation, check the current feature set against your requirements before switching.

Do I need to know Rust to use it? No. Rust only matters if you plan to build from source or contribute code. Prebuilt binaries require no development environment.

Which version should I download? v0.16.1 is the current stable release. Earlier versions are still on the mirror for reference but lack the newer sketch and constraint improvements.

Does it run on Linux? Yes. Source builds work across Windows, macOS, and Linux, and the Rust toolchain is the only build dependency.
