Instruction can be found in the on-line help - search for "Create or edit symbol fill".
Once you have created the fill you can create (or edit) a material that has that hatch pattern attached so you can simply attach it to your walls by assigning the correct material.
You must allow for vectorial hatching to be turned on in your elevation settings.
