What is the method to unlock from a sketch plane?

To unlock from a sketch plane in Solid Edge, clicking the unlock icon is the correct method because it directly allows you to disengage the sketch from that particular plane. When you are in the sketch environment, this feature is essential for transitioning to different operations without being bound to the constraints or geometry that are specific to the initial sketch plane. The unlock icon serves as a quick and intuitive tool for users to manage their workflow efficiently within the sketching environment.

The other methods provided do not specifically facilitate the unlocking process related to a sketch plane. Right-clicking the sketch may bring up a context menu with various options, but it does not have a dedicated function for unlocking the sketch plane. Pressing the "Esc" key generally cancels the current action or exits commands, but it does not change the locking status of the sketch. Similarly, holding down the "Shift" key might modify selection behaviors or allow for additional actions, but it is not designed for unlocking a sketch plane. Therefore, utilizing the unlock icon is the most straightforward and effective approach for this task.
