The foundation of all innovative planning tools is the representation of a construction on a 3D model (Allplan). We have implemented 3D planning as a standard for a long time now, as we consider it indispensable for architects and building owners to be able to make a reliable assessment of the chosen support system. Moreover, this prepares us well for the future in terms of BIM (Building Information Modeling).
