Grouping
Using the grouping functionality in Revit Structure, you can create reusable entities that represent layouts common to
many building projects. By grouping objects, you not only simplify their placement, you also simplify the modification
process. For example, when you make changes to a single instance of a model group, all instances in the building model
are updated, and all new instances that you place contain the modifications.
You can also nest groups within other groups. In this tutorial, you create a model group for a typical kitchen, and then
you nest the kitchen in a 2 bedroom condominium unit group. Modifications to the nested group are automatically
included in the host group.
Saving a group to a library gives you the ability to share the group with other team members working on the same project,
or with those working on a different project. This functionality ensures consistency within and across projects. It also
gives all those with access to the library the ability to load any group from the library into their project drawing. Because
existing groups can be duplicated and then customized for another purpose, creating a library of groups for your office
can reduce the amount of work needed to create, place, and modify repetitive units.
Creating, Modifying, and Nesting Groups
In this lesson, you learn how to use model groups to collect related elements to simplify placement of
repetitive units. Examples of the types of units for which groups are intended include condominium units,
hotel rooms, and typical office layouts.
After you create a model group, you can place instances of the group in the building model using various
methods. You can also update all instances of a group in the building model by editing a single instance of
the group and saving the changes.
In another exercise, you add the new model group to a previously created group. The new group is considered
nested within the host group, and is contained in every instance of the host group that you place in the
building model. When you make changes to a nested group, the host group is also updated automatically.
Creating and Placing a Group
In this exercise, you create a model group for a typical kitchen for a condominium unit. You create the group
by selecting drawing objects and grouping them as a single entity.
In this exercise, you place 2 new instances of the kitchen group in the floor plan. You mirror one instance
of the group, and rotate the other instance to modify the layout position.
