The ‘IFC (BIM) import basis’ module allows importing various objects of IFC4 and IFC2x3 classes (from construction, installations, and other fields) without their interpretation. It is possible to load multiple models simultaneously. The objects are visible in both the 2D editor and the 3D view. Managing the imported model is facilitated by a special Project Browser, with information visible in the Data Table. Objects from the model can be marked or hidden. They are also visible for the SNAP function when editing other areas in the 2D editor. Models (as a whole) can be deleted or re-imported.

Models loaded using this module can be interpreted in terms of construction together with the ‘IFC (BIM) building data interpretation’. Only the geometry of the model can serve as a background for installations designed in InstalSystem 5, without the need for interpretation. Working with the model also enables the detection of collisions between objects present in the IFC and the installations designed in InstalSystem 5. IFC models can be exported to DXF/DWG and PDF formats.
