What feature would you use to create a hole in a part with a defined diameter?

The feature used to create a hole in a part with a defined diameter is the Cut Extrude. This feature allows you to specify a circular profile, such as a circle with a defined diameter, and then extrude that profile through the material of the part. The result is a solid model with a hole that extends in a specified direction and depth, effectively removing material from the part.

Cut Extrude is particularly useful because it can be applied to various geometries and can be configured with additional parameters such as depth, direction, and whether to cut through the entire part or a specific distance. This versatility makes it a common choice for creating holes in parts within Solid Edge.

In contrast, other options like Fillet, Revolve, and Extruded Surface serve different purposes. Fillet is used to create rounded edges on part features, Revolve is used to create 3D features from 2D shapes by revolving them around an axis, and Extruded Surface is intended for creating surfaces rather than solid features. Thus, these options do not fit the specific requirement of creating a hole with a defined diameter.
