3D Scratchpad vs Solid Engineer

3D Scratchpad is an easy-to-use, full-featured design tool for creating 3D models. Freehand draw in three dimensions using simple primitive solid shapes and intuitive gestures. Manipulate objects as if they were in the real world with augmented reality, and share your models as .usdz files for viewing in augmented reality. 3D Scratchpad creates a short path between design ideas and useful 3D models for designers, modelers, makers, gamers, 3D-printing enthusiasts, hobbyists, educators, engineers, and architects. Use 3D Scratchpad to create and fabricate prototypes, to model new products, parts, and structures, and to create and share 3D art and designs. 3D Scratchpad enables you to design in the real world. Built to enable immersive, intuitive, and interactive design, 3D Scratchpad unlocks your design creativity and gives you the tools you need to create and share 3D models. Purchasing an auto-renewing 3D Scratchpad Subscription enables the ability to save and share 3D models.

Learn programming and create 3D models that can be printed or shared with other users. The 'basic' mode helps students to learn the basics of programming by dragging and dropping programming statements. The 'advanced' mode supports subtracting and intersecting volumes, profiles, parameters, part libraries and keyframe animation. In the 'programmer' mode you can use the power of modern JavaScript such as arrow functions, maps and filters.
