How do you lock a sketch plane after selecting a face?

To lock a sketch plane after selecting a face in Solid Edge, it is essential to ensure that your sketch remains fixed in its intended position relative to the selected geometry. Clicking the Lock Icon achieves this by constraining the sketch plane, which prevents accidental movement or modification of the sketch layout as work continues. This is particularly useful in maintaining design integrity when making changes or adding new features.

The other options do not serve to lock the sketch plane effectively. For instance, clicking the Save Icon is related to saving your work rather than locking sketches, while pressing the Shift Key typically modifies selection behavior rather than affecting plane constraints. Similarly, double-clicking the face may provide access to different features or options but does not specifically execute the function of locking the sketch plane. Hence, utilizing the Lock Icon is the appropriate method to achieve the desired outcome in the Solid Edge environment.
