For architectural design projects, while there is emphasis on the use of 3D models and the BIM architectural modeling, the proven practice of using architectural drafting and 2D engineering drawings is still common in the AEC industry. Architectural editing has moved from the drawing board to computer-aided design and design (CAD) software. Writing practices help to provide architectural construction drawings that include technical details of the architectural, structural and electrical elements required for the construction of a building. To understand the architectural drafting phase, one must take into account the workflow of a construction design cycle.

The basic workflow of an architectural design project begins with the architect creating a conceptual plan that is typically modeled in 3D model architecture and rendered as photorealistic images for Marketing and presentation to customers and customers.

Once the design is approved by the customer, the design is then advanced in more detail and shared with other parties, such as structure and MEP Engineers. The way the design progresses for the "design development" phase by an architect lends itself to two options, either to develop a 3D model with more detail and then create sheets and subsequent details using the " 39, a 3D tool such as Revit or AutoCAD, or equally popular, to develop 2D concept design using more traditional methods. From the conceptual plans provided by architects and engineers, an editor can convert these models by using CAD software to create technical drawings.

Architectural drafting is the process of creating technical drawings including floor plan, sections, elevations, detailed drawings and other documents in a construction drawing set CD set), which are usually required for the construction of a building.

The difference between architectural drafting and modeling

Architectural drafting refers to the creation of 2D technical drawings and architectural construction drawings that are mainly used by Contractors and on-site consultants. Architectural 3D modeling refers to the creation of 3D models and photorealistic images that are primarily used to present architectural design for marketing purposes and then progressed from there to create 2D technical drawings, feeling like a Additional step (the 3D modeling element). The main software used for writing, to create 2D technical drawings is AutoCAD while the model makers use Revit and ArchiCAD to create 3D models and rendered images. Architectural designers must have basic knowledge of 2D and 3D software such as AutoCAD and knowledge of technical codes and drafting guidelines specified by organizations such as American National Standards Institute (ANSI), American Society of Mechanical Engineers (ASME), American Design Drafting Association (ADDA), Public Works Government Services Canada (PWGSC), National Institute of Building Science (NIBS), BSI British Standards Institute and Standards Australia Code AS1100. Architectural modelers must have a deeper understanding of architecture, construction and construction concepts and experience with 3D software such as Revit and ArchiCAD.

Why architectural design is still common in architectural design practices

3D architectures are preferred by architects and designers because they offer a 3D perspective The conceptual design of the building; It makes project data management easier and allows design changes on the road. However, construction companies that require technical specifications of the architectural project prefer 2D drawings and architectural construction drawings as they provide accurate details required for construction, most of the resources involved in construction include 2D drawings, There are no problems with software compatibility compared when using 3D models and this is a solution tailored to the budgetary requirements of a construction project. Some of the reasons why architectural drafting is preferable by several construction companies include:

• Suitable according to construction requirements – In some construction projects, 2D drawings or drawings Architectural CADs are sufficient to complete Construction, where additional information provided by 3D models is not required. A construction drawing set (CD set) includes all floor plans, elevations, sections and detailed drawings required for construction. Technical codes, symbols and other additional information such as the type of equipment are provided in the technical drawings. Therefore, construction companies find 2D technical drawings sufficient to complete the construction.

• Availability of technical resources – Not all companies have technical resources to deliver 3D models. While editorial teams are qualified to work on AutoCAD to provide 2D technical drawings, they may not be qualified to work on Revit to deliver 3D models. In the construction sector, the availability of editorial teams that can provide 2D technical drawings is vast compared to companies that provide 3D modeling services.

• Availability of software – The adoption of new software and practices are gradual and slow in the construction industry. The software used in construction projects varies from one country to another. Some countries use ArchiCAD and AutoCAD Architecture instead of Revit, thus leading to project data incompatibility. The 2D drawings in AutoCAD are widely used and compatible, making it a preferred option for Revit 3D models.

• Suitable for budgetary and budgetary needs – In most cases, construction companies do not find the need to invest more in 3D models when solutions Provide sufficient detailed technical drawings relevant to the construction. There is also additional investment in sufficiently competent resources to understand and implement 3d models of on – site architecture.

While architectural 3D modeling and BIM modeling provide design information typically required for architects and designers at the stage of life cycle design Of the construction project, architectural drafting provides technical drawings that not only concern the aesthetics but also the high performance details of the building elements. Architectural CAD profiles specifically communicate the design intent and contribute to the construction of buildings that companies find sufficiently relevant on 3D models. Although construction companies must ultimately evolve to combine the use of 2D engineering drawings and architectural 3D models until then, the proven practice of using architectural design and architectural solutions Drawing in construction is here to stay.
