a family type definition ripple through the project and are automatically reflected in every instance of that
family or type within the project. This keeps everything coordinated and saves you the time and effort of
manually keeping components, and schedules, up to date.
The Family Editor is a graphical editing mode in Revit Architecture that allows you to create families to
include in your project. When you start creating a family, you open a template to use in the editor. The
template can include multiple views, such as plan and elevation views. The editor has the same look and
feel as the project environment in Revit Architecture, but features different commands on the Design Bar
and can open multiple views, depending on the template chosen.
Family Editor Commands
Revit Architecture features a Design Bar for creating the actual representation of the family. Availability of
commands depends on the type of family you are creating.
Command Descriptions
■
The Family Types command opens the Family Types dialog. You can create new Family Types or new
Instance and Type parameters. See Family Types on page 366.
■ The Dimension command adds permanent dimensions to the family, in addition to the ones Revit
Architecture automatically creates as you sketch the geometry. This is important if you wish to create
different sizes of the family. See
Placing Permanent Dimensions on page 215.
■ The Model Lines command lets you sketch 2-dimensional geometry for when you do not need to show
solid geometry. For example, you could sketch door panels and hardware as 2-dimensional rather than
sketch solid extrusions. Model lines are always visible in 3D views. You can control their visibility in
plan and elevation views by selecting the lines and clicking Visibility from the Options Bar. See
Setting
Family Geometry Visibility on page 360.
■ The Symbolic Lines command lets you sketch lines that are meant for symbolic purposes only. For
example, you might sketch symbolic lines in an elevation view to represent a door swing. Symbolic lines
are not part of the actual geometry of the family. Symbolic lines are visible parallel to the view in which
you sketch them.
You can control symbolic line visibility on cut instances. Select the symbolic line and click Visibility
from the Options Bar. Select Show only if instance is cut.
In this dialog, you can also control the visibility of lines based on the detail level of the view. For example,
if you select coarse, that means that when you load the family into a project and place it in a view at the
coarse detail level, the symbolic lines are visible. See
Detail Level on page 503.
TIP Use this dialog to control visibility of generic annotations loaded into model families. See Loading Generic
Annotations into Model Families on page 422.
■ The Lines command sketches lines to define the geometry of the family. See Model Lines on page 741.
■ The Opening command is available in host-based family templates only, for example, wall-based or
ceiling-based. You create an opening by sketching its shape to the reference planes and then modifying
its dimensions. After creating an opening, you can select it and set it to appear transparent in 3D and/or
elevation views when loaded into the project. From the Options Bar, select the 3D and/or Elevation check
boxes next to Transparent in.
NOTE The Opening command is also available in the project environment. See Openings on page 658.
■ The Ref Plane command creates a reference plane, which serves as a guide for sketching lines. See Reference
Planes on page 1046.
