What function does the F3 key serve in Autodesk Inventor?

In Autodesk Inventor, the F3 key is primarily assigned to the "Free Orbit" function. This feature allows users to manipulate the view of a model interactively, providing more flexibility when examining complex assemblies or parts from various angles. By pressing F3, users can click and drag to orbit around the model in a free manner, which facilitates a better understanding of the spatial relationships and design details.

Other options encompass different functionalities: the "Previous View" typically allows users to return to the last view they were using, while "Zoom" focuses on magnifying or reducing the display of the model. "Home View" resets the view to a default orientation. Understanding these different functions helps users navigate Autodesk Inventor more effectively, utilizing keyboard shortcuts for improved workflow efficiency.
