What is one way to remove an existing sketch in SolidWorks?

One method to remove an existing sketch in SolidWorks is to select it and then press the Delete key. This action effectively deletes the sketch from the feature tree, allowing for modifications in the design without that particular sketch present.

Using the Delete key is a straightforward and efficient way to manage sketches as it is a common function across many software applications. This method provides a quick removal process, especially when you are working within the context of modifying sketches or managing the feature tree directly.

The other options could include alternative ways to manage sketches, but they either do not exist in the SolidWorks interface or aren't standard functions for deleting sketches. Thus, relying on the Delete key is the most widely recognized and accepted method for this task.
