BIM (Building Information Modeling) technology is increasingly used in building design. Classification and management of layers based on Open BIM (IFC classification) is avilable in the CADprofi program. BIM data is included in specifications and can be transferred to applications that are used during the investment phase. Additionally our company creates data in BIM (including rfa Revit format) for many manufacturers. 3D models included in our software can also be used in many CAD programs that allow to import and export files in IFC standard.
