Revit Materials Living in a Material World Elise Moss Adjunct Faculty Laney College For Rendering For Scheduling To control hatch patterns To control appearance of objects How are Materials used in Revit? Revit divides materials into TWO locations Materials in the Project Autodesk Asset Library You can also create one or more custom libraries for materials you want to use in more than one project You can only edit materials in the project or in the custom library – Autodesk Materials are read-only Revit manages Materials Materials have FIVE asset definitions – Identity, Graphics, Appearance, Physical and Thermal Materials do not have to be fully defined to be used- YOU DON’T HAVE TO DEFINE ALL FIVE ASSETS Each asset contributes to the definition of a single material APPEARANCE IDENTITY MATERIAL THERMAL GRAPHICS PHYSICAL Materials have FIVE ASSET definition tabs Assets are the ingredients that make up the Material You can define Appearance, Physical, and Thermal Assets independently without assigning/associating it to a material You can assign the same assets to different materials An asset can exist without being assigned to a material BUT a material must have at least THREE assets (Identity, Graphics, Appearance) Assets can be deleted from a material in a project or in a user library, but you can not remove or delete assets from materials in locked material libraries, such as the Autodesk Materials library, the AEC Materials library, or any locked user library. You can delete assets from a user library – BUT be careful because that asset might be used somewhere! Assets act separately from materials You can only duplicate, replace or delete an asset if it is in the project or in a user library You can duplicate an asset and re-define it This material only has three assets assigned – Identity, Graphics and Appearance. You can add additional asset definitions by clicking the + button. This Appearance definition is being used by eight materials. A zero next to the hand means that only the active/selected material uses the appearance Reading the Material Editor Clicking on the + shows a drop-down of the remaining assets you can add to a material By default, any material has THREE assets defined: • Identity • Graphics • Appearance Adding an Asset Definition The value in the Description field can be used in Material tags. Using comments and keywords can be helpful for searches Product Information is useful for material take-off scheduling The most useful for me is filling out the keynote information The Identity Tab Material Tags use the values from the Identity tab Description field Just start typing in the Class text field to add a custom class definition. The custom class will appear in the dropdown list. Keep in mind that any changes you make are only valid to the active project unless you copy the material to a custom library To Add a Class It is helpful for students and users to become familiar with the way keynotes are assigned Once the keynote is located, it is auto-filled in the dialog box. The keynote value is automatically copied from the keynote database. Keynotes The user has to enter in the desired Mark/Callout. Graphics control how the material looks non-rendered, such as: The color that displays in a shaded view. The color and pattern that display on the surface of an element. The color and fill pattern that display when the element is cut (section view). The Graphics Tab Shading – Determines the color and appearance of a material when view mode is SHADED. If you have Use Render Appearance Unchecked – then the material will show a color of the material when the display is set to Shaded The Graphics Tab If Use Render Appearance is checked – then the material uses the Render Appearance Color when the display is set to Shaded SHADED REALISTIC UNCHECKED CHECKED Comparing Checked to Unchecked Surface Pattern will be displayed in all the following Display settings: Wireframe/Hidden/Shaded/Realistic/Consistent Colors Cut Patterns appear in section views Graphics tab – Surface/Cut Pattern The Coarse Scale Fill Pattern is used in floor plans to designate different wall types, flooring, slabs, or materials – these should correspond to any legends used. It is defined in the Type Properties for the object – not in the Materials. Display setting must be set to coarse to see hatch/fill pattern The Coarse Scale Fill pattern is used to designate materials in legends Another Place for Fill Pattern Appearance controls how material is displayed in a rendered view, Realistic view, or Ray Trace view. The Appearance Tab Different Material Types can have different Appearance Parameters The assigned class controls what parameters can be assigned to the material – if you create a custom class, it will use Generic parameters This information may be used for structural and thermal analysis of the model You can only modify physical properties of materials in the project or in a user library Physical Tab The Thermal tab is only available in Revit This information is used for thermal analysis and energy consumption Thermal Tab You can only add or remove categories from custom libraries Material Libraries organize materials by Category/Class Material structural classes are organized into the following types: Basic Generic Metal Concrete Wood Liquid Gas Plastic This family parameter controls the hidden view display of structural elements. If the Structural Material Class of an element is set to Concrete or Precast, then it will display as hidden. If it is set to Steel or Wood, it will be visible when another element is in front of it. If it is set to Unassigned, the element will not display if hidden by another element. Material Structural Classes When assigning a material Material already in Project? Copy Material to Project YES YES Assign the Material NO Material in Asset Browser? NO Create a new material from a similar material or use GENERIC Creating a new material Material will be used in more than one project? NO CREATE NEW MATERIAL IN PROJECT YES ADD MATERIAL TO CUSTOM LIBRARY Will Material Tags be used? If yes, then add desired description for material tag Will keynotes be used? If yes, then assign keynote Will material be used for cost estimating? Add cost and manufacturer information Add comments and keywords to help with material searches Identity Tab Check list when adding a new Material • What color do you want to see in shaded views? • What hatch pattern do you want to use to identify the element/object type? Graphics tab Checklist Do you want to render the material using Color Image Metal Appearance Tab For paints For ceramic surfaces For plastics When do you use Color only? By adding finish bumps, a relief pattern and tint, you can add interest to any color Don’t be afraid to experiment – the more you play, the more you learn Just Because it is a Color doesn’t mean Boring To convey a sense of 3D/depth For plants, wallpaper, decals, murals, wood, tile, etc. Revit supports image files of the following types: BMP, JPG, JPEG, and PNG. When do you use an Image? Use Maps to enhance Images Reflectivity – controls what appears in reflective surfaces – like metals Transparency – controls the transparency of a surface – like glass or water Cutout – adds a see-through appearance – apply to chain link, screens, catwalks, or fences Self-illumination – makes the object appear to glow – use on LED screens, billboards, or televisions Bump- gives the appearance of bumpiness or “noise” – use on cobblestones, lawns, fabric, marble, or stone The Different Types of Maps Right click on the image and select Edit Image, then browse for the desired image file To select/assign an image to a material Added a Checkered Cutout to this fabric Locate a material similar to the one you want, if you can (otherwise, use Generic) Duplicate the material Rename Modify the Identity, Graphics, and Appearance Tabs Apply to the object Preview using Realistic or Raytrace Adjust the definition as needed Steps to create a new material Locate a similar material. Right click and select Duplicate Rename Fill out the Identity Data Assign Colors and Hatch Patterns Click on the link and browse for a new image to be used Edit Image and then select a new image Edit the Information and preview the image Select a new Bump image or adjust the other map images as needed See how the new material looks in the model Project Materials Material Libraries Asset Manager Be Familiar with the different panels in the Material Browser Toggles the display of libraries Controls what you see in the dialog Opens/Closes the Material Editor/Asset Browser You can create your own custom library of materials to be shared across projects or use someone else’s custom library Material Libraries Elise Moss [email protected] Questions?
