3D visualisation

Late last year DDA made some significant hardware and software upgrades to allow better, faster and more realistic 3D visualisations. While looking through the projects, you may have noticed the category ‘current’ which are either in development stage or tender stage. To help ourselves and our clients get a better understanding of how the completed building will look, we turn to 3D modelling software.

There are two types of 3D models we use:

1: Building information models (or BIM). These are working models in Revit, and include all the plans, elevations and details within the model. Final construction documents can be produced directly from here and are usually used between design stage through to construction stage.

2: Sketch models. These are built in Sketchup and are usually used as a design tool in the early stages of a project. They are quick, flexible and have no restrictions in terms of shape or form. These can become construction documents after they are exported into Autocad or Revit.

These 3D models can then be presented in two ways:

1: As is. Using the built in materials and basic shadowing that is included in the project. This is very quick and doesn’t require any further work other than adding some people, backgrounds/collage and a titleblock. This is suitable for most projects as it has a sketchy, almost cartoon look to it and makes it easy for changes to occur.

2: Rendered. This takes the model into another program where photo-real materials, textures, objects and lighting can be added. This adds extra time, not only for setting up the scenes but also for the program to complete the render at an appropriate size. This is suitable for high-end projects, marketing and special areas that rely heavily on special lighting such as bars and gaming rooms.
