SketchUp

SketchUp is a user-friendly 3D modeling application famous for its push/pull tool, making it exceptionally accessible for conceptual design. It shines in architectural, interior, and landscape design for quickly massing out ideas. The web-based version (SketchUp Free) offers core functionality, while Pro adds advanced tools and documentation via Layout. Its primary audience includes architects, builders, woodworkers, and educators.

It scores well for its ease of use and speed in the early design phases, though it is less suited for high-detail organic modeling or animation, positioning it as a great entry point and conceptual tool.
