There are 2 methods for creating a new family:
■ Creating In-Place Families: This method of family creation is for families that are unique to the current
project. They are useful for custom families, such as a furniture family for a unique reception area desk.
You can design the family in the context of existing geometry of the project. The family updates
automatically if the project changes and those changes affect the family.
■ Standard Component Families: Typically these families are standard sizes and configurations of common
components and symbols used in the building design. You define the geometry and size of the family
by using the standard family template. You can then save the family as a separate Revit family file (RFA)
and load it into any project you want. There are many templates available to use to create different
families.
After you select the template to use, you define the appearance of the family in the various views. The
geometry you put in the family is up to you and your design requirements. In some cases, such as a symbol,
you may wish to see only sketched lines. In other cases, such as furniture, you may want to see the actual
geometry of the component in a 3D view; however, in the plan and elevation views, you may want just a
2D symbolic representation to appear. You decide what geometry to create.
All family templates are stored under the Templates folder, Imperial or Metric. The Templates folder includes
2 subfolders: Annotations, for creating annotation families, and Titleblocks, for creating new titleblocks.
The Library folder contains subfolders to organize different families: either ones you created or predefined
families.
Family Templates
When you create a family, Revit Architecture provides you with a template that serves as a building block
and contains most of the information needed by Revit Architecture to place the family in the project. Among
other elements, the template can include reference planes, dimensions, and pre-defined geometry, such as
window trim.
Basic Family Templates
Following are the basic kinds of family templates:
■ Wall-based
■
Ceiling-based
■ Floor-based
■ Roof-based
■ Standalone
■
Line-based
■ Face-based
Wall-based, ceiling-based, floor-based, and roof-based templates are known as host-based templates. A
host-based family can only be placed in a project if an element of its host type is present.
The wall-based template is for components inserted into walls. Wall components can include openings,
such that when you place the component on a wall, it also cuts an opening in the wall. Some examples of
wall-based components include doors, windows, and lighting fixtures. Each template includes a wall; the
wall is necessary for showing how the component fits in a wall.
