How are cutouts or extruded cuts created in a drawing?

Cutouts or extruded cuts are essential features in solid modeling and are primarily created by removing material from existing features. In this context, the process involves defining a profile, which represents the shape of the cutout, and then applying it to a solid body to eliminate the material in that area.

This method of creating cutouts allows for precise control over the final shape of a part, enabling designers to customize components efficiently based on functional requirements. By defining the cutout profile, the user determines which section of the solid will be removed, thus allowing for more complex and functional designs.

The other methods listed do not pertain to the creation of cutouts. Adding material from profiles focuses on building up features rather than removing them, duplicating existing features involves creating copies without altering material structure, and masking parts of the drawing does not change the solid geometry in any meaningful way for cut creation.
