BlocksCAD is described as '3D CAD program specifically designed to help kids create 3D printable objects while learning math and programming' and is an website. There are six alternatives to BlocksCAD, not only websites but also apps for a variety of platforms, including Linux, Mac, Windows and Chrome OS apps. The best BlocksCAD alternative is OpenSCAD, which is both free and Open Source. Other great sites and apps similar to BlocksCAD are Antimony, MakerSCAD, OpenJSCAD.org and ImplicitCAD.
OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and MacOS.
Antimony is a computer-aided design (CAD) tool from a parallel universe in which CAD software evolved from Lisp machines rather than drafting tables.
MakerSCAD is a web-based parametric 3D design software with a block-based programming language to create objects for 3D printing, animations, games and websites.
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.
ImplicitCAD is a programmatic CAD program, implemented in Haskell. Unlike traditional CAD programs, programmatic CAD programs use text descriptions of objects, as in programming. Concepts like variables, control structures and abstraction are used, just as in programming.
Online platform for generating 2D/3D CAD and manufacturing drawings with javascript. Result can be published as online configurator applications. Enables Mass Customization in Manufacturing.
