The basic method of using the Rotate (Q) tool is fine when you need to rotate something on the ground plane, but this method isn’t as useful when your axis of rotation isn’t vertical. Finding a face to use to orient your cursor can be tricky or impossible, and that’s where a lot of SketchUp modelers get hung up.

With this not-so-basic rotation method, you can establish a precise axis of rotation (the invisible line around which you’re rotating) without having any existing faces to use for orientation. This makes rotating things about a million times easier.

In this case, using the Rotate (Q) tool goes from being a five-step operation to a seven-step one. Check out Figure 3-25 for a visual explanation:

1  Select everything you want to rotate.

2 Activate the Rotate (Q) tool.

3 Click to establish your axis of rotation, but don’t let go; keep your finger on your mouse button.

4 Drag your cursor around (still holding down the mouse button) until your axis of rotation is where you want it.As you drag, notice that your Rotate protractor changes orientation; the line from where you clicked to your cursor is the axis of rotation.

5 Release your mouse button to set your axis of rotation.

6 Click (but don’t drag) the point at which you want to pick up whatever you’re rotating.

7 Click again to drop the thing you’re rotating where you want it.
