You may not have Sketches turned on from the View drop down menu. Go to View and checkmark Sketches. You should then see any sketches you have shown or not inserted into any features. If you still can’t see the sketch in the graphics area, find the sketch on the feature manager tree, right-click it and hit Show. This will make the hidden sketch visible.
