What Solid is

Solid is a visual programming and 3D modeling tool for learning computer science, designing concepts, and preparing products or buildings for 3D printing. Basic mode uses drag-and-drop statements powered by Google Blockly. Advanced mode adds rotations, sweeps, extrusion profiles, walls, parametric parts, keyframe animation, mathematical expressions, and material properties. Programmer mode lets users write JavaScript in a text editor with ECMAScript 2019 support. Documented operations include transformations, Boolean operations, repetition, conditionals, profiles, materials, parts, expressions, and animation. Teachers can create assignments by showing students a target model to reproduce with a program. Solid offers parametric modeling, animation tools, and 3D-print export through browser access, iPhone and iPad apps, Android phones and tablets, or a self-hosted server installed with Docker. It is described as a module of the 3D-T digital-twin environment.
