Use this procedure to display a previously hidden surface hatch.
An object must have a surface hatch material assigned to it in order to add an override to a surface hatch. A surface hatch on an object can come from an assigned material or from the display properties of the object or object style.
If a surface hatch comes from the display properties of the object instead of from the material assignment, you cannot override it on individual faces. You receive an error message upon selecting the object face.
