Which option would you choose to extrude a sketch curve until it intersects with another curve or edge?

Choosing the option to "Stop at Intersection" allows for an extrusion that precisely terminates at the intersection point between the sketch curve and another curve or edge. This capability is particularly useful in scenarios where a clean and specific geometric relationship is desired. With this option, the extrusion does not extend beyond the intersection, ensuring that the resultant shape adheres to the geometry of the design without unnecessary overlap or misalignment, allowing for cleaner modeling and integration within complex assemblies.

In contrast, the other options offer different benefits: "Until Next" would continue the extrusion until it reaches the next existing geometry which might not be the intersection point of interest. "Infer Curves" is used to create new curves based on existing geometry rather than controlling the extrusion length directly. "Connected Curves" focuses on ensuring the extrusion follows a continuous path when multiple curves are involved, but it does not limit the extrusion based on intersections specifically.

Therefore, selecting "Stop at Intersection" is the best choice for controlling the extrusion precisely where it intersects with another feature, maintaining the integrity of the design.
