The Graphics tab of the Materials Browser contains parameters for Surface Pattern which control hatch patterns in Revit.If unable to find an appropriate hatch pattern for your materials in Revit, users can create their own with Manage tab / Materials.You will then have the choice of creating additional patterns and/or uploading new patterns into Revit. It won't take long for you to outgrow the fill patterns available in Revit. 'Model' patterns are typically used for surfaces, therefore appear on plans and elevations. These types of patterns do not have a size and change depending on scale being used in the Revit view. 'Drafting' patterns are most often used for cross sections. These patterns come with two types: Drafting and Model. Called 'Filled Patterns' in Revit, these can be found under the Manage tab, Additional Settings and Fill Patterns. Like Autocad, Revit Architecture comes with a handful of hatch patterns. Hatch patterns are incredibly useful graphics that communicate that materials used on your drawings.
