  1. Revit Materials Living in a Material World Elise Moss Adjunct Faculty Laney College

  2. For Rendering • For Scheduling • To control hatch patterns • To control appearance of objects How are Materials used in Revit?

  3. 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

  4. 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 Assets are the ingredients that make up the Material IDENTITY GRAPHICS MATERIAL Materials have FIVE ASSET definition tabs PHYSICAL THERMAL

  5. 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

  6. 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

  7. 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

  8. 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

  9. 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

  10. Material Tags use the values from the Identity tab Description field

  11. Just start typing in the Class text field to add a custom class definition. The custom class will appear in the drop-down 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

  12. 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. The user has to enter in the desired Mark/Callout. Keynotes

  13. 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

  14. 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 If Use Render Appearance is checked – then the material uses the Render Appearance Color when the display is set to Shaded The Graphics Tab

  15. SHADED REALISTIC CHECKED UNCHECKED Comparing Checked to Unchecked

  16. 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

  17. 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

  18. Appearance controls how material is displayed in a rendered view, Realistic view, or Ray Trace view. The Appearance Tab

  19. Different Material Types can have different Appearance Parameters

  20. The assigned class controls what parameters can be assigned to the material – if you create a custom class, it will use Generic parameters

  21. 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

  22. The Thermal tab is only available in Revit This information is used for thermal analysis and energy consumption Thermal Tab

  23. You can only add or remove categories from custom libraries Material Libraries organize materials by Category/Class

  24. 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

  25. Material already in Project? Assign the Material YES Copy Material to Project NO Create a new material from a similar material or use GENERIC Material in Asset Browser? NO YES When assigning a material

  26. Material will be used in more than one project? ADD MATERIAL TO CUSTOM LIBRARY YES NO Creating a new material CREATE NEW MATERIAL IN PROJECT

  27. 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

  28. 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

  29. Do you want to render the material using • Color • Image • Metal Appearance Tab

  30. For paints • For ceramic surfaces • For plastics When do you use Color only?

  31. 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

  32. 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?

  33. Use Maps to enhance Images

  34. 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

  35. Right click on the image and select Edit Image, then browse for the desired image file To select/assign an image to a material

  36. Added a Checkered Cutout to this fabric

  37. 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

  38. Locate a similar material.Right click and select Duplicate

  39. Rename

  40. Fill out the Identity Data

  41. Assign Colors and Hatch Patterns

  42. Click on the link and browse for a new image to be used Edit Image and then select a new image

  43. Edit the Information and preview the image

  44. Select a new Bump image or adjust the other map images as needed

  45. See how the new material looks in the model

  46. Project Materials Asset Manager Material Libraries Be Familiar with the different panels in the Material Browser

  47. Toggles the display of libraries Controls what you see in the dialog Opens/Closes the Material Editor/Asset Browser

  48. You can create your own custom library of materials to be shared across projects or use someone else’s custom library Material Libraries
