Families
The object categories are divided into families. Families can be system, in-place, or external.
System families are built into templates and projects, and in most cases cannot be completely
removed. System families can be:
Model elements (walls, columns)
•◆
Datum elements (grids and levels)•◆
View-specific elements (text notes, tags)•◆
System families are easily identified by checking the family name of an element in the Element
Properties dialog box. The name of the family is prefaced by System Family (see Figure 1.17).
External families are loaded from the Revit Structure content libraries as well as from your own
custom created libraries. You load them in as you need them. These family files can be created
from scratch using a default template shipped with the program, by using a custom template, or
by copying and modifying a similar existing family.
