To rotate an object in SketchUp Free, follow these simple steps:

Step 1: Open your SketchUp Free software and load the 3D model that you want to rotate.

Step 2: Select the object that you want to rotate by clicking on it.

Step 3: Once the object is selected, hover over the object until you see the rotation handle. It looks like a circle with a compass-like icon.

Step 4: Click and drag the rotation handle to rotate the object to the desired angle. You can also use the protractor tool to enter specific rotation angles.

Step 5: Release the click to set the object at the new angle.

Step 6: If you want to rotate the object around a specific point, you can use the rotate tool. Click on the rotate tool in the toolbar, then click on the point where you want the object to rotate around. After that, move your mouse to define the axis of rotation and click again to set the rotation.

By following these steps, you can easily rotate objects within your SketchUp Free software, allowing you to enhance your 3D modeling designs and create dynamic visualizations for your projects. Keep practicing and experimenting with different rotation angles and pivot points to master the art of object rotation in SketchUp Free.
