Tinkercad

This free web-based 3D design and electronics platform enables beginners, students, and educators to create 3D models, electronic circuits, and block-based code through an intuitive drag-and-drop interface accessible directly in a web browser without software installation, making 3D design and STEM education accessible to users of all ages and skill levels. The 3D modeling workspace uses a shape combination approach where users add primitive shapes including boxes, cylinders, spheres, and pyramids to a workplane, then modify them through scaling, rotation, and grouping operations, with the ability to create holes by designating shapes as negative space, enabling construction of complex geometries through boolean union and subtraction operations that would require advanced skills in traditional CAD software. The electronic circuit simulator provides a virtual breadboard where users place components including LEDs, resistors, batteries, switches, sensors, and microcontrollers, wire them together with virtual jumper wires, and simulate circuit behavior with animated current flow and component activation, teaching electronics fundamentals without requiring physical hardware. The code blocks interface introduces programming concepts through visual block-based coding similar to Scratch, enabling users to create animations and interactive projects that respond to simulated inputs, bridging the gap between coding education and physical computing concepts. The lesson plans and classroom management tools support teachers in implementing design and engineering curricula. The export options include STL files for 3D printing. Designed for students, educators, makers, hobbyists, and beginners learning 3D design and electronics.
