You can choose from several different wheels. Each has its own drafting theme, and is designed for a different type of 3D navigation.
Wheels are available in two sizes: big and mini. The big wheel is larger than the cursor. A label is on each wedge in the wheel. The mini wheel is about the same size as the cursor. Labels are not displayed on the wheel wedges.
You can choose from the following wheels:
The View Object wheel is for general 3D navigation; it includes the orbit 3D navigation tool. Use the View Object wheel to examine 3D objects from the outside.
The Tour Building wheels are designed for 3D navigation within the interior of a model.
The Full Navigation wheel combines navigation tools found on the View Object and Tour Building wheels.
