3D computer-aided design (CAD) modelling has transformed the way building designs are generated for the better. Construction professionals that have embraced this new technology stand a better chance of succeeding in today's highly competitive construction industry. If you still rely on 2D CAD models to generate architectural and engineering designs for your building construction projects, here's why you should seriously consider making the upgrade to a 3D CAD model. 

Time savings

With 3D CAD models, the shared 3D CAD data allows for simultaneous operation of engineering and manufacturing processes. In addition, the integrated operation of systems in 3D modelling allows building design professionals to get the answers they need without spending long hours trying to get an accurate interpretation of data from 2D CAD drawings. This, in turn, allows building designers to work more efficiently, and therefore complete their projects in record time.

More precision

With 3D CAD designing, everything is done in a single model, whereas designing with 2D CAD modelling is typically carried out in multiple models. Designing in multiple models increases the likelihood of errors occurring as information is being exported. 3D models, on the other hand, facilitates better coordination of the designing process. 

Compared to 2D CAD models, the precision that can be gained with 3D CAD models is unequalled, especially when used in tandem with a 3D mouse. Every part of a building can be measured and analysed independently, offering unparalleled insight when making designs.

For example, construction teams can generate and export 3D CAD models directly into GPS-guided excavation equipment. This gives construction workers on the ground direct access to accurate 3D designs for use in site excavation.

More control over the design process

3D CAD models gives project managers and teams complete control over site conditions. Architects and engineers can test various 'what if' scenarios and validate their plans by using their 3D models as tools of analysis. By performing simulation analysis with 3D designs, for example, building designers are able to visualise what could happen in each scenario. 2D CAD drawings usually can't be manipulated this way. 3D CAD models is also an indispensable tool for costing as well as reviewing of construction volumes.

Overall, the introduction of 3D CAD modelling has significantly improved the efficiency at which building designs are produced and used. If you want happy clients, it may be a great move to switch from 2D to 3D modelling.
