3D CAD modelling has application for the road, civil engineering and construction environment. We create models that can be used for a variety of purposes throughout the project life cycle, especially to generate powerful photorealistic visualisations of highways, tunnels (BD78/99), lighting, traffic, traffic management, CCTV surveillance, electronic and static roadsigns and other highway items of interest. The resulting CAD models can also be used for other purposes:
- drawing & document management systems
- contract tendering
- internet web display
- exhibition / powerpoint kiosk display
- meeting / conference room display on LCD / Plasma
- corporate / business reception display on LCD / Plasma

For larger schemes, we can obtain appropriately scaled ordnance survey maps with which a contoured landform model is created as illustrated on Contoured OS Landform Model. Crude block representations of highway objects and associated buildings can be inserted into 3D CAD models to provide results which, even at this conceptual stage, provide powerful images that provide a platform conveying scale and purpose providing a medium for further creative inspiration and ideas.
It should be noted that ordnance survey maps are not always an essential starting point. It is possible to use client existing 2D drawings and use these together with survey data to generate the required 3D CAD model. We have motorway field experience of collating motorway survey data, including street furniture, lighting and communications equipment using EDM and GPS.
To develop and enhance the model a stage further, we then replace block representations, with 3D CAD models of road construction, objects (such as trees, street furniture, safety fencing, vehicles) and further local topographical survey data as required. This is an iterative process and once finalised, the model and resulting 4D CAD animation can be rendered to incorporate the required material and textures. |
