If that doesn't suit you, our users have ranked more than 50 alternatives to OpenSCAD and many of them is free so hopefully you can find a suitable replacement. Other interesting free alternatives to OpenSCAD are Autodesk Fusion, FluidCAD, Dune 3D and BRL-CAD.
A powerful open-source parametric 3D modeler ideal for mechanical engineering, supporting Python scripting, running on Windows, Linux, and Mac, with modular architecture allowing extensive adaptability and use with scientific computing libraries.
Integrated CAD, CAM, and CAE suite offering cloud modeling, simulation, and manufacturing tools with collaborative editing, free-form and parametric design, licensing for students, hobbyists, and startups, plus support for 3D printing and CNC machining.
Parametric 3D CAD in browser using JavaScript scripting, fully interactive viewport editing, non-destructive feature tree control, direct geometry referencing, rapid prototyping, STEP import/export, smart defaults, minimal math, and open source availability.
Dune 3D operates as a parametric 3D Computer-Aided Design (CAD) software. It provides users with the capability to sketch and constrain both in 2D and 3D dimensions. Furthermore, it allows for the addition of chamfers and fillets to designs.
BRL-CAD is a powerful cross-platform open source solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, image and signal-processing tools, a system performance analysis benchmark suite, libraries for...
System for processing and editing 3D triangular meshes, provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes.
OpenJSCAD.org is a more up-to-date OpenJsCAD frontend where you can edit .jscad files either locally or online via JS editor (built-in). A few functions are available to make the transition from OpenSCAD to OpenJSCAD easier (OpenSCAD.
CadQuery is an intuitive, easy-to-use Python module for building parametric 3D CAD models. Using CadQuery, you can write short, simple scripts that produce high quality CAD models. It is easy to make many different objects using a single script that can be customized.
Antimony is a computer-aided design (CAD) tool from a parallel universe in which CAD software evolved from Lisp machines rather than drafting tables.
CAD Sketcher is a free and open-source project looking to enhance precision workflows in Blender by bringing CAD like tools, features and usability to Blender.
A declarative parametric 3D modeling application built using Open Cascade (pythonocc) and enaml (python). It's similar to OpenSCAD in that everything is intended to be defined programatically.
