No one wants to waste time learning complicated software. SketchUp Pro is hands-down the most intuitive and easy-to-learn 3D drawing tool on the planet. We designed SketchUp to behave like an extension of your hand. The idea is to get out of your way so that you can draw whatever you want, however you want. We love how architects use layers and layers of tracing paper to develop and improve their ideas. Similarly, SketchUp was born to be simple to let you iterate. SketchUp isn’t just for 3D models. Draw plans, elevations, details, title blocks and other graphics with LayOut. When your model changes, so does your document. Simple. SketchUp Pro includes LayOut, an incredibly powerful tool with features for page layout, drafting, vector illustration and slide presentations. Use SketchUp Pro to turn your models into animated walkthroughs and flyovers that explain every detail of your design. Need an oven for the kitchen you’re designing? An automobile for your driveway? A rhino for your zoo? Find it all in 3D Warehouse, the world’s biggest library of free 3D models. Eventually, some 3D models grow up to become professional 2D drawing sets. LayOut in SketchUp Pro helps you showcase your models and create drawings you’ll be proud of. SketchUp extensions are add-on tools built to solve the kind of 3D modeling problems that might otherwise leave you scratching your head. And there are hundreds of them for you to explore. Source.
