3D Slash is a unique, block-based 3D modeling software designed to make 3D design intuitive and accessible for everyone, from children and educators to hobbyists and professionals. Inspired by the visual simplicity of retro video games, it uses a 'destruction' and 'construction' metaphor where users carve models out of a virtual block of material using tools like a hammer, chisel, and trowel, rather than manipulating complex vertices and polygons. This gamified approach significantly lowers the learning curve associated with traditional CAD software. It is widely used in educational settings to teach STEM concepts, design thinking, and spatial reasoning. Users can create models for 3D printing, game assets, architectural visualizations, and simple prototypes directly in a web browser or via desktop applications. The platform emphasizes creativity, speed, and fun, positioning itself as a bridge between playful digital making and practical 3D output.
