SketchUp’s Tape Measure tool, Protractor tool, and the Measurements box help add accurate measurements to your designs. These tools offer several ways to add precision to a model:With the Tape Measure tool (), you can measure a distance and set precise guide lines or guide points.

When you create a 3D model, you often need to draw a slightly bigger or smaller version of a shape and keep the two shapes equidistant from each other. This is called offsetting a line. An offset is handy when:

The SketchUp Follow Me tool () leads a face along a path to create a 3D shape. The Follow Me tool does only one thing. However, it has a multitude of applications and can help you draw complex 3D models with only a few clicks.

In SketchUp, you can resize and reshape your model based on the relative sizes of edges and faces. With SketchUp’s scaling tools you can:

With SketchUp's flipping and rotating tools, your geometry becomes as nimble as an acrobatic troupe. The Flip Along command enables geometry to backflip 180 degrees along any axis. With the Rotate tool, your geometry can spin and fold like a professional gymnast.

Everyone makes mistakes. In SketchUp, you can correct mistakes with the Undo command or the Eraser tool.Using the Undo CommandThe Undo command reverses your most recent action. For example:

When you move geometry that's connected to other geometry, SketchUp stretches your model.To stretch your geometry, select the Move tool (). Clicking and dragging different parts of an entity will give the following results:

When you're drawing a model in SketchUp, moving all or parts of your model can be tough, especially when navigating geometry in a three dimensional space. Here's your guide to moving things around in your 3D model, from a simple click-and-move operation to moving precisely with 3D coordinates.To perform a simple move operation follow these steps:

As you draw 3D models in SketchUp, dividing edges and faces can help you create and manipulate your geometry in complex ways. You can also explode entities, such as circles and polygons, into their individual segments.Dividing a Line or ArcSketchUp splits a line segment when a new line is drawn perpendicular to that line. For example, when two lines are drawn perpendicular to each other on the face of the cube:

With SketchUp's Freehand tool (), you can create hand-drawn lines. The Freehand tool is handy when you need to trace imported drawings, create a 2D sketch, or decorate your model.
