Typically, designs are developed using 2D drawings and several iterations are required before the final solution is agreed. The drawings make up part of the construction documentation – or deliverables – that are required for every project. While used for a vast range of applications across many industries, 2D CAD is used within the architecture, engineering, and construction (AEC) sector for creating construction drawings that describe how a project is built. 3D design is slightly different to 2D design as a 3D model is created using volumes (rather than areas) which depict different components within the project, such as walls, floors, and roofs.ĢD CAD uses two-dimensional components such as arcs and lines to create line drawings of products and structures. 2D design is predominantly done using 2D software where lines and arcs are used to create plan, elevation, and section views of the proposed structure. What Is The Main Difference Between 2D And 3D?ĢD and 3D design is used in the architecture, engineering, and construction (AEC) industry to prepare construction documentation such as drawings and layouts that describe how a project should be built.However, with 2D drawings still dominating the project deliverables, being able to work in both 2D and 3D is beneficial. Moving from 2D to 3D CAD lets architects, civil engineers, and designers work more efficiently and accurately.
