WHAT’S 3D MODELING?

3D Modeling is an expansion on the concept of two-dimensional drafting that began to rise in popularity in the early 2000’s. By adding a third dimension there is exponentially more information that can be included in the resulting model. Three-dimensional models in AEC design are typically for buildings and building systems, however, they can be utilized for individual components and fixtures for fabrication as the building gets closer to construction.
Models are created in the early stages of a design project and are used as the foundation for designers to bring designs into reality in the form of detailed construction drawings, images, and renderings.



What are its Benefits?
The benefits of working in three-dimensional space over traditional drafting are that it allows architects and engineers to more clearly understand the conditions of a design. The design of building systems is complex and can be utilized to more clearly represent projects to other designers, builders, and clients.
Models make it is possible to make large changes to design with relative ease as the drawings are based on 3D geometry instead of linework. By making changes easier designers are able to more easily coordinate with trades and consultants after presenting design options. If all members of the design team are working in 3D it is possible to have a complete digital representation of the design and all of its systems. This also opens up other opportunities for coordination such as clash detections and material quantities to be more accurately estimated to help keep project costs low.
Other information can also be included in a model, such as glazing information for windows, hardware information for doors, pipe flows, mechanical system volumes, and electrical design loads. This information component allows projects to have more information incorporated into the design reducing the potential for coordination errors and miscommunications. Once the project is complete, the design model acts as a record model for the owner and any future maintenance teams.
