Which key is used for accessing the Free Orbit tool?

The Free Orbit tool in Autodesk Inventor is a powerful feature that allows users to rotate the 3D model freely in any direction, giving a comprehensive view of the design from different angles. The function is essential for visualizing the model in a more dynamic and detailed manner, aiding in design review and presentations.

Using the F4 key is significant because it directly corresponds to the specific command designed for activating the Free Orbit tool. When you press F4, the view transitions into an orbit mode, allowing you to click and drag to rotate the model. This shortcut enhances workflow efficiency since accessing the tool through the navigation bar or menu can be cumbersome and time-consuming.

The other function keys do not relate to the Free Orbit tool specifically, making F4 the correct choice for this functionality, as it is designed explicitly for providing that level of interaction with your 3D design. Understanding keyboard shortcuts like this is important for maximizing productivity when using Autodesk Inventor.
