With 3D modeling, a third dimension is introduced. In BIM projects, 2D drawings still play an important role, especially when it comes to construction planning with a high level of geometrical detailing or communication on site. The projection planes are usually planar but can be curved along an axis and planarized later too, especially in infrastructure. In this case, the designer uses CAD as a digital, 2D drawing board and the viewer of the drawings has to interpret how the drawings relate to each other to imagine the building. For floor planes, it is an XY-plane, while for sections and views the projection plan has a Z axis. A plane is defined and all information necessary to describe the building is projected on it. When dimensions go beyond 2D CAD or 3D modeling, what does it mean? What do the other dimensions refer to, and what are the benefits of incorporating more dimensions? Here is a brief overview of the different dimensions used in CAD and BIM, and what you can expect from 5D BIM.Įveryone within the architecture, engineering, and construction (AEC) industry knows what 2D CAD is – the main deliverables of every project are made up of two-dimensional drawings that depict the proposed project from different angles and at in different levels of detail. 5D BIM is one area that has been attracting increased interest from the BIM pioneers, but for many, it is not clear what 5D BIM is. The different dimensions of CAD – and, by extension, Building Information Modeling (BIM) – are something that many architects, engineers, and contractors are familiar with, at least to a certain extent.
