The 3D view is useful for visualizing the project, while 2D views and sections can be quickly created as a byproduct of the 3D model. Even existing site inspection data can be included to create a 3D topographical map of the site. These components can be standard building parts taken from a library – much like blocks in 2D CAD – or can be designed to the exact project specifications. Rather than drawing 2D shapes and lines to define a structure, 3D construction models are created by combining 3D components such as walls, beams, columns, or even steel reinforcement to create an accurate virtual model of the proposed project. How Does 3D Modeling Software Work in Construction? With 3D CAD programs, however, this is much easier and faster to achieve, as well as being more accurate. Typically, 2D CAD has been used to create construction drawings of projects, with many different layouts required in order to generate a complete picture of all aspects of the building or structure.

Because 3D design has several advantages compared to 2D CAD, many architects, engineering consultancies, and contractors are implementing 3D modeling software within their business. Designing in three dimensions using 3D modeling software is rapidly becoming the accepted method of planning and constructing buildings.
