The 3D design workspace uses a simple "building block" geometry system. Users drag predefined shapes (cubes, cylinders, spheres) onto a workplane, adjust their dimensions, and combine them. By turning shapes into "Holes," you can cut away material from solid shapes to build complex, custom 3D models perfect for 3D printing. 2. Circuits

The Circuits environment allows you to design and simulate electronic systems virtually. You can wire up components like resistors, LEDs, and pushbuttons, or prototype advanced systems using virtual Arduino Uno and Micro:bit microcontrollers. The platform includes a real-time simulator to test your circuit functionality safely before buying physical hardware. 3. Codeblocks
