Example: Create and connect Electrical System the Mechanical System

Part 1: Create New System Component: Ventilation Unit

Select the Item group that you want to add the System to. In this case we will be selecting ’03 - HVAC & Plumbing’
Select the lowest level of the Item group. For this example, we will select ‘03 – Mechanical’
With the Item Group highlighted, Select New System Component
In the Window that appears you will be able to select an Item from the Item group using the dropdown menu. In the case we are selecting the item 0303.001 - M_Air Handling
Fill out the information in the window. Serial number, name and select the team responsible. This information can be edited later
Click ok

You have added an Air Handling unit.

Part 2: Create New System Component: Electrical Panel

We now want to create our Electrical System to connect to the Mechanical System that we just created.

To connect the two Systems, go to the Electrical Item Group. In this case we will be selecting ’04 - Electrical’
Select the Service Panel Group. For this example, we will select ‘07 – Service Panels’
With the Item Group highlighted, Select New System Component
In the Window that appears, select an Item from the Item group using the dropdown menu. We are selecting the item 0407.001 - Ward room panel
Fill out the information in the window. Serial number, name and select the team responsible. This information can be edited later

Now that we have our Panel created, we can create a circuit that will connect the Electrical and Mechanical Systems.

We can do this by connecting the Panel to the Air Handling unit in the other System.

Part 3: Connect the Electrical and Mechanical Systems

Connect the Panel to the Air Handling unit by adding a component to the System as a member

Select Add Member and then search for the component you want to connect to
Select the Component and then select Create new System.
We are going to call this ‘Ventilation Offices’

By completing these steps, you have connected multiple Systems for the Items that exist in your project.

In addition to this, you can complete this process using the Omni Class system. For those familiar with this categorization system, it makes a quick reference to see where items and occurrences are linked to. dRofus can deliver Omni Class numbers to the model, which is helpful if you want unique numbers on components.

The advantage to this approach is that that you can quickly build out your Systems with items and occurrences and they will already exist in your dRofus project. This means in an early phase, you can add items and they will be visible across the disciplines on the project.
