SketchUp is meant to be customized. Thanks to our Ruby API and an amazing community of developers, today you can explore an entire universe of extensions. These are add-on tools built to solve the kind of 3D modeling problems that might otherwise leave you scratching your head. Need to draw 3D moldings? There’s an extension for that. Wouldn’t it be cool to bend your models to fit a curve? That’s possible, too. Photorealistic rendering? Definitely. If you can imagine a SketchUp extension, chances are it already exists.
