Pertaining to architectural design projects, during your stay on island is the emphasis on using 3D models and new BIM modeling, the proven practice of using system drafting and 2D specialized drawings is still very common in the AEC industry. Architectural drafting has advanced from enter board to computer-aided design and composing (CAD) software packages. Drafting methods help to provide new construction drawings which include the technical details of system, structural and electrical elements required for the building of a building. To understand the stage when architectural drafting takes place, the workflow of a building design lifecycle must be considered. Jay Belson
The standard work flow of an architectural design project starts with the architect creating a conceptual plan which is usually modelled into architectural 3D IMAGES models and rendered as photorealistic images for marketing and presentation to clients and customers.
When the conceptual design is approved by the client, the design is then progressed into more detail and given away to other parties such as structural and MEP engineers. The way in which the design is progressed 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 subsequent bed linens and details by using a 3 DIMENSIONAL tool such as Revit or AutoCAD, or as is still commonplace, to develop the concept design in 2D using time-honored methods. From the conceptual plans provided by designers and engineers, a painter can convert these designs using CAD software programs to create technical sketches.
Architectural drafting is the process of creating complex drawings which include the floor plan, sections, elevations, detailed drawings and other documents in a building drawing set (CD Set), which are typically necessary for the construction of a building.
The between Architectural Drafting and Modeling
Architectural drafting identifies creating 2D technical drawings and architectural construction drawings which are mainly employed by technicians and consultants on site. Architectural 3D modelling recognizes creating 3D models and renders of photorealistic images which are mainly used to present the system design for marketing purposes and then progressed from there to create the 2D technical drawings, in effect feeling like an extra stage (the 3D IMAGES modelling element). The primary software used for drafting, to create 2D technical paintings is AutoCAD while modellers use Revit and ArchiCAD to create 3D models and rendered images. Executive draftsmen need to have basic 2D and 3 DIMENSIONAL software knowledge such as AutoCAD and familiarity with specialized codes and drafting suggestions specified by organisations such as American National Requirements Institute (ANSI), American Culture of Mechanical Engineers (ASME), American Design Drafting Connection (ADDA), Public Works Govt Services Canada (PWGSC), Domestic Institute of Building Savoir (NIBS), BSI British Requirements Institute and Standards Sydney Code AS1100. Architectural modellers need to have a deeper knowledge of architectural, building and construction concepts and experience with 3D software programs such as Revit and ArchiCAD.
Why New Drafting is still Prevalent in Architectural Design Methods
Architectural 3D models are preferred by architects and designers because they provide a 3D perspective of the conceptual plan of the building; it makes management of project data easier and enables design changes on the go. Yet , construction companies that require technical specifications of the architectural project favor 2D technical drawings and architectural construction drawings because they provide accurate details required for construction, almost all of the resources involved in construction understand 2D images, there will be no issues with compatibility of software in comparison with when using 3D models in fact it is a suitable solution to meet the budgetary requirements of a construction task. Some of the reasons why architectural drafting is preferable by several development companies include:
– Suitable as per building requirements – In some building projects, 2D complex drawings or architectural CAD drawings are sufficient to complete construction, where additional information that 3D models provide is not necessary. A construction drawing established (CD set) includes all the floor plans, elevations, sections and detailed paintings necessary for construction. Techie codes, symbols and other additional information including the type of material are provided in technical drawings. For that reason, construction companies find SECOND technical drawings sufficient to successfully complete construction.
– Accessibility to technical resources – Not every companies have technical resources to deliver 3D models. While creating teams are qualified to work on AutoCAD to provide 2D technical drawings, they may well not be qualified to work on Revit to deliver 3D models. In the construction industry, the availability of drafting groups who provides 2D technological drawings is ample in comparison to companies that provide THREE DIMENSIONAL modelling services.
– Availableness of software – The adoption of recent software and practices is steady and slow in the construction industry. The software found in building projects differs from country to country. Some countries use ArchiCAD and AutoCAD Architecture rather than Revit, therefore leading to the incompatibility of task data. 2D technical paintings in AutoCAD are generally used and compatible rendering it a preferred option to Revit 3D models.
– Suitable as per cost and budgetary requirements – In many instances, construction companies do not find the need to invest more in 3D models, when composing solutions provide detailed complex drawings which are sufficient and relevant enough for construction. There is also the added investment in resources that are skilled enough to understand and implement architectural 3d models on-site.
While architectural THREE DIMENSIONAL modelling and BIM modeling provide design-related information typically required for architects and designers in the design stage of the building project lifecycle, architectural composing provides technical drawings that are not merely about looks but about high-performance detail of construction elements. System CAD drawings specifically connect the design intent that help in the building of buildings which companies find relevantly sufficient over 3D models. Even as construction companies should eventually evolve to combining the use of 2D specialized drawings and architectural 3D IMAGES models until then, the time-tested practice of using architectural drafting and sketching solutions in construction is not going away.
