6 Click Ortho if you want Autodesk Navisworks to align the texture space with the nearest axis.
7 Click Fit if you want Autodesk Navisworks to fit a single repeat of the texture to the item. This is of particular
use when you are mapping an image to the exact size of the item it's being applied to.
Use Presenter Rules
Rules Tab
The Rules tab of the Presenter window allows you to apply materials to models according to certain user-defined
criteria, rather than by dragging and dropping onto individual layers, groups or components. For example, all
layers that are floors can be assigned a material called “floorboards”, without having to manually drag and drop
the material on to each floorboard. Each time the model is updated, the rules then just need re-applying, rather
than manually re-applying materials to all items.
All materials can be saved in a Autodesk Navisworks “palette” NWP file, which allows you to set up a palette of
materials once for a project and re-apply them to a model as it evolves, or to another model in the same project
that has been set up with the same layer names, colors, selection sets and/or properties.
See “
Organize and Manage Materials” on page 355 for more information.
Predefined Rules
You can apply as many rules at once, as all rules depend on material names. Rules can be defined using the
Autodesk Navisworks API, but the predefined rules are:
■ Layers by Name enables you to apply a material to named layers.
For example, if a layer is called “Doors” and you rename a material to “Doors” (the spelling and case must
be exactly the same as the layer’s name) then all layers named “Doors” will display the properties of that
material when you select the rule Layers by Name, and click Apply.
You can give multiple materials the name of different layers and apply this rule to all of the layers.
■ Autodesk Navisworks Materials by Name enables you to apply a material to named Autodesk Navisworks
materials. Autodesk Navisworks materials are not the same as Autodesk Navisworks Presenter materials.
Autodesk Navisworks materials merely refer to the color and transparency of the item as saved in the original
CAD file, whereas Presenter materials are those materials applied using the Presenter tool, or are more complex
materials, such as bitmaps converted from the original CAD file.
If a Presenter material has the same name as a Autodesk Navisworks material in the model (for example,
“AutoCAD Color Index 7”), then all items with this original Autodesk Navisworks material name in the scene
receive this Presenter material from the palette when you select the rule Autodesk Navisworks Materials by
Name, and click Apply.
■ Selection Sets by Name enables you to apply a material to selection sets. See “
Create and Use Sets of Objects”
on page 229 for more information on setting up selection sets.
