Which option in the extrude dialog projects an extrude to the side walls of a pocket?

The feature that allows you to project an extrude to the side walls of a pocket is known as "Open Profile Smart Volume." This option is specifically designed to recognize and utilize an open profile, allowing for the extrude to engage with the geometry of a pocket or similar feature. When selected, it intelligently determines the boundaries and projects the volume of the extrude within that defined area, adapting to the pocket's side walls.

In contrast, the other options serve different purposes within the extrude dialog. The draft option is used to add or modify an angle to the sides of the extruded feature, which influences the tapering of the extrude rather than directly interfacing with pocket walls. The offset option allows for the creation of an offset volume from the selected profile, affecting the distance from the original contour rather than projecting it into side walls. Finally, the direction option simply defines the orientation of the extrusion, such as whether it should extrude upward or downward from the sketch plane, without the specific functionality to engage with the geometry of pocket walls.
