Why The Time-tested Practice of Architectural Drafting is Used in Architectural Design?

Why the time-tested practice of Architectural Drafting is used in Construction and Architectural DesignArchitectural drafting, a time-tested practice of drafting 2D architectural construction drawings has evolved from manual 2D drawing to using computer-aided design and drafting (CAD) software programs. 2D drawing sets have been used and will continue to be used by engineers, designers and architects as standard deliverables to contractors on construction sites.Architectural drafting, a time-tested practice of drafting 2D architectural construction drawings has evolved from manual 2D drawing to using computer-aided design and drafting (CAD) software programs. 2D drawing sets have been used and will continue to be used by engineers, designers and architects as standard deliverables to contractors on construction sites.

In most building projects today you may have noticed an increase in the use of architectural BIM modeling and 3D models. Architectural 3D modelling is useful because 3D architectural construction drawings and models allow for design changes in real-time, easier management and exchange of project data and it provides a 3D view of the conceptual plan. However, architectural drafting is preferred by several construction companies because it includes technical details of structural, architectural and electrical components required for installation and during construction of a building. A construction drawing set (CD set) of architectural CAD drawings typically includes sections, elevations, floor plans, detailed drawings for installation of MEP components and other documents required for construction.

Architectural CAD drawings help in construction and architectural design by specifically communicating the design intent and by providing high-performance detailing of construction elements. To understand why the time-tested practice of architectural drafting is commonly used in architectural design and construction projects, here are some of the reasons:

• While architectural design companies have technical resources and drafting teams qualified to deliver 2D technical drawings using basic software programs such as AutoCAD, not all companies have the availability of technical resources qualified to deliver 3D models using software programs such as Revit. Moreover, most of the resources employed in construction teams are qualified to interpret 2D architectural construction drawings required for construction while not all resources working in various disciplines are experienced to use 3D models.

• In the construction industry, the adoption of new practices and the latest software is a slow and gradual process. The software programs used in architectural design and building projects varies from country to country, with some using AutoCAD and ArchiCAD instead of Revit, invariably resulting in the incompatibility of project data. 2D architectural CAD drawings are widely adopted across the industry and are preferred over Revit 3D models for construction.

• While 3D models provide additional information, not all building projects require this data to complete construction. 2D architectural CAD drawings in a construction drawing set include symbols, technical codes, quantities, the type of material and other additional information included in the elevations, sections, floor plans and detailed drawings that are required for successfully completing a construction project.

• One of the underlying reasons why architectural drafting solutions are commonly used is the fact that 2D technical drawings are economically viable and provide sufficient project data to complete construction. Moreover, added to the cost of architectural 3D modelling solutions, there is an additional investment in technical resources qualifies to interpret architectural 3D models for construction on-site.

The practice of using 2D architectural construction drawings on-site will continue to be a preferred option because construction companies and teams need more than a 3D perspective of the conceptual plan, they need precise details and accurate drawings for construction and detailed technical drawings more than an aesthetical perspective. Moreover, in the construction industry, most of the resources can interpret 2D drawings clearly and not all manpower of various disciplines in a construction team have the capability to comprehend 3D models. Added to that, 2D drawings are compatible because basic software programs such as AutoCAD and ArchiCAD is required unlike when using 3D models where there are certain cases of software incompatibility. While architectural design and construction companies gradually adopt architectural 3D modelling and BIM modelling solutions, architectural drafting and drawing solutions will continue to be a commonly used practice because it meets the requirement of efficient and effective construction on time and within budget.
