In Revit they are called fill patterns, and they are created the same in a titleblock family as they are in a project. Simple linework patterns can be created in Revit without an import. If you need somethign else a standard PAT file can be used.
There is an add on to Revit called Hatch-22 that can be used to help you create a custom PAT file which can be used to create custom Revit fill patterns.
