After saving the document (Ctrl+S or Save), this feature enables users automatically return to the last active sketch (provided the Save command has been invoked from the active Sketch environment). This removes one extra step that is required to go back to the sketch to continue the editing.
Standard Inventor behavior is such the user must exit the sketch before saving the document (or the sketch can be exited automatically). After saving, the user has to manually activate the sketch to continue the editing.
By default, this feature is disabled. It can be enabled using the Enable checkbox.
Check/uncheck the checkbox.
Use your normal sketch editing workflow.
