SketchUp: Free to Download

SketchUp offers a free, downloadable version called SketchUp Make. It includes essential tools for 3D modeling and can be expanded with various plugins. While it may not have all the features offered in the Pro version, SketchUp Make is a comprehensive tool for beginners. It encompasses different modeling modes, extensive object library, 3D warehouse integration, and easy collaboration via Trimble Connect. Despite being free to download, SketchUp Make can handle most consumer-level 3D printing jobs and architectural, civil, and mechanical design tasks.
