Modifying Families - Autodesk Revit Architecture 2015 Essentials - page 152

The Defines Origin parameter can also be set in elevation for spe-
cific types of families, such as wall-based families. For example, this
may be useful for wall cabinets where specifying an exact elevation
for the top of cabinets is required.

7. Select the Upper Cabinet family above the desk family, and click Edit
Family in the ribbon to open the cabinets in the Family Editor.

8. Open the Placement Side elevation view, and select the reference
plane at the top of the cabinets. Select the check box for the Defines
Origin parameter in the Properties palette as you did for the refer-
ence planes earlier (Figure 6.17). Note that the reference plane eleva-
tion is 6 ′ -0 ″ (2000 mm) above the floor line.

Only one horizontal
reference plane can be
checked in an elevation
view for the Defines
Origin parameter.

9. Click Load Into Project from the ribbon to reload the family into the
project, and select Overwrite The Existing Version as you did earlier.
Notice that as with the desk, the Upper Cabinet family updates to
reflect the new origin.

10. From the Level 1 floor plan view, place a new instance of the over-
head cabinet family on any of the walls.

Notice that the default elevation when placing an instance in the
floor plan view matches the 6 ′ -0 ″ (2000 mm) elevation of the refer-
ence plane. If you select the family, there is an Elevation instance
parameter in the Properties palette, which should be set to 6 ′ -0 ″
(2000 mm) (Figure 6.18).
