How are Materials used in Revit?
For RenderingFor SchedulingTo control hatch patternsTo control appearance of objects
Revit manages Materials
Revit divides materials into TWO locations
Materials in the ProjectAutodesk 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
Materials have FIVE ASSET definition tabs
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
MATERIALIDENTITY GRAPHICS
APPEARANCE
PHYSICALTHERMAL
Assets are the
ingredients that make
up the Material
Assets act separately from materials
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!
You can duplicate an asset and re-define it
You can only duplicate, replace or delete an asset if it is in the project or in a user library
Reading the Material Editor
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
Adding an Asset Definition
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
The Identity Tab
The most useful for me is filling out the keynote information
Product Information is useful for material take-off scheduling
Using comments and keywords can be helpful for searches
The value in the Description field can be used in Material tags.
Material Tags use the values from the Identity tab Description field
To Add a Class
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
Keynotes
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.
The Graphics Tab
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
If Use Render Appearance is checked – then the material uses the Render Appearance Color when the display is set to Shaded
Comparing Checked to Unchecked
SHADED
REALISTIC
UNCHECKED CHECKED
Graphics tab – Surface/Cut Pattern
Surface Pattern will be displayed in all the following Display settings:Wireframe/Hidden/Shaded/Realistic/Consistent Colors
Cut Patterns appear in section views
Another Place for Fill 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
The Appearance Tab
Appearance controls how material is displayed in a rendered view, Realistic view, or Ray Trace view.
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
Physical Tab
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
Thermal Tab
The Thermal tab is only available in Revit
This information is used for thermal analysis and energy consumption
Material Libraries organize materials by Category/Class
You can only add or remove categories from custom libraries
Material Structural Classes
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.
When assigning a material
Material already
in Project?
Assign the MaterialYES
NO
Material in Asset Browser?
Copy Material to
Project
Create a new material from a
similar material or use GENERIC
NOYES
Creating a new material
Material will be used in more than
one project?
YESADD MATERIAL TO CUSTOM LIBRARY
NO
CREATE NEW MATERIAL IN PROJECT
Identity Tab Check list when adding a new Material
Will Material Tags be used?If yes, then add desired description for
material tagWill keynotes be used?
If yes, then assign keynoteWill material be used for cost estimating?
Add cost and manufacturer informationAdd comments and keywords to help with
material searches
Graphics tab Checklist
• What color do you want to see in shaded views?• What hatch pattern do you want to use to identify the
element/object type?
Appearance Tab
Do you want to render the material using Color Image Metal
When do you use Color only?
For paintsFor ceramic surfacesFor plastics
Just Because it is a Color doesn’t mean Boring
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
When do you use an Image?
To convey a sense of 3D/depthFor plants, wallpaper, decals, murals,
wood, tile, etc.Revit supports image files of the following
types: BMP, JPG, JPEG, and PNG.
Use Maps to enhance Images
The Different Types of Maps
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
To select/assign an image to a material
Right click on the image and select Edit Image, then browse for the desired image file
Added a Checkered Cutout to this fabric
Steps to create a new material
Locate a material similar to the one you want, if you can (otherwise, use Generic)
Duplicate the materialRenameModify the Identity, Graphics, and
Appearance TabsApply to the objectPreview using Realistic or RaytraceAdjust the definition as needed
Locate a similar material.Right click and select Duplicate
Rename
Fill out the Identity Data
Assign Colors and Hatch Patterns
Edit Image and then select a new image
Click on the link and browse for a new image to be used
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
Be Familiar with the different panels in the Material Browser
Project Materials
Material Libraries
Asset Manager
Toggles the display of libraries
Controls what you see in the dialog
Opens/Closes the Material Editor/Asset Browser
Material Libraries
You can create your own custom library of materials to be shared across projects or use someone else’s custom library
