## 7.13. Grouping and ungrouping

Grouping of components is designed for creating a certain structure of an installation. For instance, groups are used for duplicating by means of expanding groups (see section 7.10.2), for renumbering of pipe-runs and appropriate presentation of calculation results.

Each group has the following characteristics:

1. None of its components may be placed outside the group.

2. When you move a group, all its components are moved with it.

3. When you move a group component outside of the borders of the group, the extent of the group is automatically broadened.

¨ To group components:

1. Mark the components. You can use all techniques described in sections 4.8.2 and 4.8.6.

2. Select “Components / Group” (Ctrl+G, ).

! It is not possible to group one single component.

A group is displayed surrounded by a brown frame:

When you click within the group area where there is no component the group is marked and group data are displayed in the data table. The marking of the group is indicated by an appropriate caption in the status line, by thicker lines of the group frame, and the contents of the data table.

! Make sure whether a group or only one of its components is marked – this is particularly important when you intend to delete a group component only.

You can create nested groups, which means that one group can be included within another group.

You can also ungroup components.

¨ To ungroup components:

1. Mark the group.

2. Select Components / Ungroup (Ctrl+H, ).

3. The group (as a kind of logical structure) is dissolved; but its components remain in the drawing.
