Your model is more than just straight lines. SketchUp can help you create curved geometry using arcs. Before you begin drawing arcs, here are a few handy details about the way arc entities work:

With the Push/Pull tool (), you can create a 3D shape from a face or cut a 3D shape out of your model. You can push/pull any type of face, including circular, rectangular, and abstract faces.The video shows you all the tricks you can do with the Push/Pull tool.

SketchUp offers two tools to help you select what entities you want to modify with SketchUp's other tools and commands - the Select tool (), and the Lasso tool (). Here's where you find these tools in SketchUp:
