CAD has appeared in design studios for thirty years and has immediately imposed technical changes, making operations faster and faster. It is in fact a design that can digitally create 2D drawings and 3D models of products, before they have ever been manufactured. 

However, while 3D CAD allows to share, examine, simulate and modify projects in a simple way, on the other hand it imposes a drawing methodology and, therefore, a precise design, which significantly affects the designer. For this reason, 3D in CAD can only be developed when the ideas are clear, because every change requires a costly destructive/reconstructive action.

Der Begriff BIM (Building Information Modeling) bezeichnet im Allgemeinen architektonische 3D-CAD der nächsten Generation, die sich nicht auf das Zeichnen einfacher grafischer Elemente beschränken, sondern Ihnen die Möglichkeit geben, durch das Zeichnen der technischen Komponenten des Gebäudes zu entwerfen.

BIM kann als eine Weiterentwicklung von CAD identifiziert werden. Der Unterschied zwischen den beiden besteht nicht einfach in der 3D-Modellierung, sondern in einer neuen Konzeption. Während das CAD-Modell eine der vielen Darstellungen des Projekts ist, ist das BIM-Modell das Projekt selbst. Es ist eine kollaborative Designmethode, die auf Integration basiert. Die verschiedenen an der Realisierung eines Werks beteiligten Akteure können das Informationsmodell bereichern, Informationen eingeben, extrahieren, aktualisieren oder ändern.à

Building Information Modelling is therefore not only a software, but a real methodology that allows you to generate a digital model as a whole.

As explained in detail in our article Dissemination BIM in Europe: where are we? is one of the 10 most promising technologies for the construction industry. It is able to reduce all obstacles to change, reversing the current trend and, unlike CAD, is more than a three-dimensional representation of the project.

Thanks to BIM it is possible to create a virtual prototype of a building with a dynamic model that contains a series of information on geometry, materials, load-bearing structures, plants, costs, safety, etc. It improves and expands data management and allows designers to work with a collaborative approach, sharing technical choices, detecting and resolving any inconsistencies and errors from the early stages.

BIM is therefore not just a 3D model, 3D is an important and fundamental part, but to which must be added a component that often tends to be forgotten: structured and shared data.
