Chapter 35. Presenter Rules
In this section you will learn how to use predefined and custom rules to apply materials to your model
faster.
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 them to all items.
All materials can be saved in a 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 Organizing and Managing Materials 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 NavisWorks API, but three predefined rules are:
Layers by name rule enables you to apply a material to named layers.
As an 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 appear with the
properties of that material when you check the rule Layers by name, and click Apply Rules.
