Permanently remove a canvas plane.
If you no longer need a canvas plane (for example, if you have finished sketching and exported the sketch image), you may want to delete it. (If you save a wire file that contains a canvas plane, the sketch image will be saved within the wire file, and the wire file may become significantly larger.)
You can also delete only the canvas information from the canvas plane (brush strokes, masks, and so on) but keep the plane.
