### 7.11.5. Creating expanding groups

An expanding group is created in a similar manner to creating a module – it is made up of single components. The difference is that in the last stage you have to group the components and determine how the group can be expanded. We will illustrate this on an example of cold and hot water riser system with circulation.

¨ To create an expanding group:

1. Create a module that will be added on when expanding a group and store it on the toolbar as described in section 7.11.2. This may be, for instance, one storey of a riser system:

2. If the basic part of the group differs from the module to be added on (e.g. a valve on circulation pipe-run is on the first storey), the required components must be added to the module being edited, if the basic part of the group does not differ from the module to be added on, skip this point.

3. Mark all components using the method of marking groups of components.

4. Group the marked components (see section 7.13).

5. Select “Modules / Group expansion manner”.

6. Specify the direction of expansion and the expanding module. The expanding module should be a module created beforehand and stored, although this may be another module.

7. Click “OK”. Arrows appear beside the marked group indicating the direction of automatic expansion

8. Specify expansion distance in the data table: distance at which the subsequent modules will be positioned (in the case of groups expanding horizontally) or difference between elevations (in the case of groups expanding vertically).

! For groups expanding vertically the expansion distance specified here will be applied during expanding only if the group is not placed on any floor elevation label type component.

9. Select “Modules / Add to toolbar”. The group is stored as a module in the “User” tab.

10. Using Modules gallery (see section 7.11.3) or button configuration in the “Configure” window (see section 7.3.3) you can change the module icon and insert a comment that will appear as a hint.
