Templates are accessed via the RDS template window (Project -> RDS templates) and the equipment template window (Project -> Equipment templates).
These windows have a list of all templates on the left-hand side. You can add new templates and delete templates in this window. When you add a new template, the system will ask you to specify a prefix and a name for the new template. The prefix is the letter or number in front of the template's serial number, .e.g. for K.020 the prefix will be K. It can be beneficial to assign different prefixes to different rooms, making it easier to distinguish between them. The serial number will be generated automatically by the system.
If you right-click on a template and select Dependent rooms, you will see a list of the rooms which are connected with this template.
On the right-hand side of the same window, you have access to editing the RDS and equipment list for the relevant templates.
