Replacements
Listings that take over the same core job as BlocksCAD.
OpenSCAD
A 3D modeller you write rather than draw: a script describes the object, and the program compiles it into a solid.
OpenSCAD replaces visual blocks with written scripts that compile into solids, is free and open source on Windows, macOS and Linux, and also has a browser playground.
Tinkercad
Create simple 3D designs and explore electronic circuits in a browser.
Tinkercad is a free browser tool using shape-based modeling rather than code blocks, with circuit and coding activities included, and it needs an account to save projects.
3D Slash
A beginner-friendly 3D modeling tool where you shape models by carving and adding blocks.
3D Slash replaces programming with carving and adding blocks, runs on desktop, mobile and web, and includes team features for schools, though pricing is not clearly shown.
CQ-editor
Build parametric CAD models with Python scripts in CQ-editor.
CQ-editor builds parametric CAD models from Python scripts as free, open-source desktop software, suiting older learners but requiring CadQuery and Python instead of blocks.
