A system component is a key primary component that owns systems. Read more about the significance of system components here: /wiki/spaces/WA/pages/1318361180.
As there is no concept for the System component in IFC 2x34, dRofus uses two ways of setting the system components for you. To keep total control of which occurrences that will be set as system components for imported systems you can manually , classify Items with a system classification . Or, you can let or dRofus automatically promote promotes the first occurrences within the system as system componentcomponents.

components manually
In order to To control which occurrences are set as system components its , it’s recommended that you to use a classification in dRofus to define which occurrences are set as system componentsthem. First you need to , use or create a an active classification that are active for Items, Systems, and is numbergivingthe number given. In the example below, we have created an example called “System classification”, ; however, this could be replaced with a project, national, or international classification.

When Items are created from the IFC file (Create Items in dRofus) you can start classify the Items, users can classifying them. In the example below we have created , note a simple classification structure with two groups, : E - Electrical and M - Mechanical.
...
When we classify, e.g., Item 0303.112, we determine that the occurrence of this Item's occurrence shall be the system component in all systems in which it is a member. If there are two occurrences in the same system with Items that are classified items, dRofus will pick the first occurrence in the list of members in the IFC file and promote it as a system component.
In the image below image , we can see the result of an import the importation of occurrences and systems. Prior to the occurrences import we classified three Items as M - Mechanical. The result is three system components, M.001 - M.002, with systems and components in the system browser hierarchy.

Automatic setting of System component
If no Items have been assigned, a system classification, dRofus, will promote the first member sin in the IFCsystem IFC system as a system component. The image below show IFCsystems shows IFC systems and their components.

In the above image, we got have 14 systems in total 14 systems. The first system (“Mechanical Exhaust Air 8”) is expanded so we can see all its members of the system. When importing the first system, the first member (“M_Exhaust Unit with Cabinet - …” Cabinet—...” highlighted in red) will be promoted as a system component in dRofus. The same logic will be applied to all 14 systems.
