IFC interface

IFC export

IFC (Industry Foundation Classes) is a data exchange format for the BIM procedure, designed and certified by buildingSMART International.

Via the IFC interface, information can be exchanged with planning stakeholders and customers who do not work with the same software, thus ensuring a reliable flow of information.

Our interface can be configured to meet almost any project requirement, so you can use CARF in all BIM projects, even with complicated IFC attribute requirements.

The IFC export of CARF components is divided into 4 main areas. (element selection, element filter, options and export).

Under Element Selection you can define what should be exported.
(“Other Objects” are e.g. MicroStation elements without CARF data mask; these are exported as Element Proxy).

In the Element Filter area you can define which elements should be exported.

Depending on the category (in this case “Data Masks”), only the filters relevant for the model are displayed.

The Options area allows e.g. the creation of groups, i.e. you can group by plant/air types/media, which allows a structured representation in the IFC.

In the Export tab, general settings for the export can be made. e.g. floor/building information can be extracted from the file name.

IFC import

With the CARF IFC import interface, information of the IFC components can also be displayed in CARF and used for information queries or analyses.

As special highlights, our IFC Import interface generates room polygons from IFC Spaces fully automatically, which can later be used for automatic height dimensioning (distance pipe/duct to ceiling/floor).

Moreover, room stamps with attributes can be generated fully automatically from the IFC file. These room stamps can then be enhanced with further information from calculation programmes. Our SOLAR heating load/cooling load interface then adopts the required power for the room, for example.
