You can rotate geometry in any plane in the 3D environment. To rotate geometry using the Rotate Tool:
- Select the Rotate tool (). The cursor will change to a protractor with a circular arrow.
- Click on the entity to rotate.
Note: You can click and drag the first point to define the axis of rotation. This is especially helpful if you need to rotate on an axis that isn't on the red, green, or blue planes.
- Move the cursor in a circle until it is at the starting point of the rotation.
- Click to set the starting point of the rotation. Use the inference tool tips to help you to find the center of the rotation.
- Move the cursor until it as at the ending point of the rotation. If the 'Enable angle snapping' checkbox is checked in the Units Panel of the Model Info dialog box, movements close to the protractor result in angle snaps, while those further away from the protractor allow free rotation.
Note: Press the Esc key at any point during the operation to start over.
- Click to complete the rotation.
Rotational stretching with Autofold
The Rotate tool can also be used to stretch geometry by selecting and rotating a portion of the geometry. Any rotational movement that would cause a face to twist in on itself or otherwise become non-planar will activate SketchUp's Auto-Fold feature.
