The object styles
dialog box gives you
graphic control of all
revit categories and
their subcategories.

Model Objects The Category column on the Model Objects tab lists all available categories
and subcategories of model elements. It is important to note that the subcategories for model
and annotation objects are created in families, which are loaded into the project or template.
This will be discussed in greater detail in Chapter 14, “Designing with the Family Editor.”
The next two columns, under Line Weight, define the line weight used when the elements are
displayed in projection or cut view. You use a projection view when you’re looking at the object
from a distance; you use a cut view when your view plane is intersecting the element as in a
section. In some categories, the Cut setting is unavailable; these element categories will never
be cut in plan or section views, regardless of the location of the view’s cut plane. For categories
that enable cut display, you can set element geometry in the Family Editor to follow that rule or
not, as shown in Figure 4.3.
Line Color and Line Pattern allow you to customize the display properties of each category
and subcategory, but remember that printing a Revit view is WYSIWYG (what you see is
what you get)—colors will print as colors unless you override them to print as grayscale or
black in the Print Setup dialog box. The last column, Material, allows you to define a default
material to be associated with the category or subcategory in case family components in that
category don’t have materials explicitly defined. If a family has materials set to By Category,
it references the material defined in the corresponding object style within the project envi-
ronment.
Annotation Objects The Annotation Objects tab is similar to the Model Objects tab except
there are no material definitions. There is also only one column for line weight (Projection)
because lines do not have three-dimensional properties like model objects and cannot
be “cut.”
