Which feature is used to create a polar array of an existing model feature?

The feature used to create a polar array of an existing model feature is the Circular Pattern. This tool allows users to replicate a selected feature around a specified axis or point in a circular manner. When using the Circular Pattern, you define the center of rotation and specify how many instances of the feature you want to create around that center, as well as the angle between the instances.

This functionality is particularly useful for modeling components that require symmetry around a central axis, such as gears, bolts, or any element that needs to be evenly spaced in a circular arrangement. The Circular Pattern provides flexibility regarding the number of occurrences and can be applied to various feature types, such as holes, extrusions, or sketches, making it an essential tool for efficient design in Autodesk Inventor.
