Design presentation and modelling

The drafting process produces a model (a physical model, a number of drawings, or a computer model) which aids and represents the design. 

The further development and application of integrated computer-assisted design and drafting is the way ahead, but the choices of methodology to be made for a real, present-day project have to be carefully considered, in particular the need and availability of suitably qualified staff to handle the project s peak load requirement. 

Even with the clearest model presentation, there is a need for the ongoing model development to be supervised by dedicated design co-ordinators. The modelling software usually includes clash detection and notification, but it is still necessary to ensure that in conflicts the most important needs prevail and to maintain the integrity of operational and maintenance access and ergonomics. There is also frequently a need for ongoing independent review of the drawings or output communication, from the point of view of their users.
