ImplicitCAD

Spec sheet

What it does

ImplicitCAD is an open-source programmatic CAD tool whose programming language compiles into 3D objects.Read 12 Oct 2026 · implicitcad.org

Intended users

The project describes itself as intended to be a serious CAD program and discusses using code and mathematical abstractions to design precise, parameterized objects.Read 12 Oct 2026 · implicitcad.org

Free plan

YesRead 22 Sep 2026 · implicitcad.org

3D print export

YesRead 22 Sep 2026 · implicitcad.org

Export formats

The online editor lists STL, OBJ, SVG, DXF, and 2D G-code for a Hacklab laser cutter as output options.Read 12 Oct 2026 · implicitcad.org

Geometry

The FAQ says ImplicitCAD supports rounded unions and a wider range of primitives and transformations than OpenSCAD.Read 11 Oct 2026 · implicitcad.org

Geometry features

The FAQ highlights rounded unions and says ImplicitCAD supports a wider range of primitives and transformations than OpenSCAD.Read 12 Oct 2026 · implicitcad.org

GitHub integration

The FAQ says the website can open a project in its editor from a URL pointing to a raw GitHub-hosted file.Read 12 Oct 2026 · implicitcad.org

GUI and API server

The FAQ says ImplicitCAD has no GUI, and mentions implicitsnap.hs as a way to compile a REST API server.Read 11 Oct 2026 · implicitcad.org

Known limits

The FAQ says ImplicitCAD has no GUI of its own, and its repository README lists multi-material/color, hull, and Minkowski sum support as unfinished.Read 12 Oct 2026 · implicitcad.org

Language options

Users can design objects with the ExtOpenSCAD language or the Haskell API, and the FAQ describes using the API from C or other languages with some work.Read 11 Oct 2026 · implicitcad.org

Language support

Users can design with the ExtOpenSCAD language or use the Haskell API; the FAQ says Haskell functions can also be exported to C for use from other languages.Read 12 Oct 2026 · implicitcad.org

Local installation

The installation page describes binary installation or building a release or development version, and says Linux distribution packages are not currently provided.Read 11 Oct 2026 · implicitcad.org

Local use

The tutorial says a local installation acts as a compiler that converts .escad files to a chosen output format, and users need a separate editor and viewer.Read 12 Oct 2026 · implicitcad.org

Model rendering

The project describes an internal near-infinite-resolution model that can be rendered as an approximating triangle mesh, raytraced image, or G-code, with quality depending on the requested output.Read 12 Oct 2026 · implicitcad.org

Online use

The installation page says ImplicitCAD can be used in the website's online editor without installing it.Read 11 Oct 2026 · implicitcad.org

Parametric design

Its programming approach supports reusable objects, automation of repetitive tasks, and parametric designs.Read 11 Oct 2026 · implicitcad.org

Parametric modeling

YesRead 22 Sep 2026 · implicitcad.org

Platform access

bothRead 22 Sep 2026 · implicitcad.org

Platform availability

The installation page says Windows and Mac packages have not been made and Linux distribution packages are not presently provided; it describes installing locally by building with GHC and cabal.Read 12 Oct 2026 · implicitcad.org

Project maturity

The FAQ says ImplicitCAD is written in Haskell and invites contributions through its hacking guide.Read 11 Oct 2026 · implicitcad.org

Project status

The repository README calls ImplicitCAD a work in progress and says its listed working features were assessed on January 26, 2020, with regressions possible.Read 12 Oct 2026 · github.com

Rendering

It can render its internal model as an approximating triangle mesh, raytraced image, or GCode.Read 11 Oct 2026 · implicitcad.org

Reusable designs

Its FAQ says objects can be abstracted and reused, designed parametrically, and made with repetitive tasks automated.Read 12 Oct 2026 · implicitcad.org

Security and compliance

The official pages opened provide no security or compliance claims.Read 12 Oct 2026 · implicitcad.org

Web editor

The online editor runs in a browser, offers a Render control, and requires WebGL.Read 12 Oct 2026 · implicitcad.org
