The document discusses the relevance of both 2D architectural drawings and 3D modeling in the architectural design industry, highlighting the evolution from traditional drafting to computer-aided design (CAD). While 3D models facilitate visualization and design modifications, 2D technical drawings remain essential for construction due to their detailed specifications. The document also notes the disparity in the availability of resources and software used in the construction sector, impacting the adoption of 3D practices.

2. For architectural design projects,
although the emphasis is on the use of
3D models and BIM architectural
modeling, the time-tested practice of
using 2D architectural drawings and
technical drawings is still common in
the AEC industry. Architectural drafting
has evolved from the drawing board to
computer-aided design and drafting
(CAD) software. Drafting practices help
provide architectural construction
drawings that include the technical
details of the architectural, structural,
and electrical elements needed to
construct a building.

3. The basic workflow of an
architectural design project
begins with the architect
creating a concept plan which is
typically modeled on 3D
architectural models and
rendered as photorealistic
images for marketing and
presentation to customers and
customers.

4. Once the conceptual design is
approved by the client, the design is
advanced to further detail and shared
with other parties such as structural
and MEP engineers. The way an
architect moves through the design
for the "design development" phase
lends itself to two options, either to
develop a more detailed 3D model
and then create subsequent sheets
and details using a 3D tool such as
Revit or AutoCAD. , or as is still
customary, develop the design
concept in 2D using more traditional
methods.

5. Architectural drawing is the process of creating
technical drawings including plans, sections,
elevations, detail drawings and other documents
in a construction drawing set (CD set), which are
usually required for construction of a building.
The difference between architectural drawing and
modeling
Architectural drafting refers to the creation of 2D
technical drawings and architectural construction
drawings which are primarily used by on-site
contractors and consultants. 3D architectural
modeling refers to the creation of 3D models and
photorealistic image renderings which are
primarily used to present the architectural design
for marketing purposes and then progress from
there to create the 2D technical drawings, which
feel actually as an extra step (the 3D modeling
element).

6. Why architectural drawing is still common
in architectural design practices
Architects and designers prefer 3D
architectural models because they provide
a 3D perspective of the building's
conceptual plan; makes it easy to manage
project data and allow for on-the-fly design
changes. However, construction companies
that require technical specifications of
architectural projects prefer 2D technical
drawings and architectural construction
drawings as they provide precise details
needed for construction.

7. Suitability for construction
requirements – In some construction
projects, 2D technical drawings or
architectural CAD drawings are
sufficient to complete the construction,
when the additional information
provided by 3D models is not required.
A construction drawing set (CD set)
includes all floor plans, elevations,
sections and detail drawings needed for
construction. Technical codes, symbols
and other additional information, such
as type of material, are provided on the
technical drawings. Therefore,
construction companies consider 2D
technical drawings sufficient to
complete the construction.

8. Availability of technical resources -
Not all companies have the
technical resources to provide 3D
models. Although drafting teams
are qualified to work in AutoCAD to
deliver 2D technical drawings, they
may not be qualified to work in
Revit to deliver 3D models. In the
construction industry, the
availability of drafting equipment
that can provide 2D technical
drawings is vast compared to
companies that provide 3D
modeling services.

9. Availability of software: The
adoption of new software and
practices is gradual and slow in
the construction industry. The
software used in construction
projects varies from country to
country. Some countries use
ArchiCAD and AutoCAD
Architecture instead of Revit,
resulting in project data
incompatibility. 2D technical
drawings in AutoCAD are widely
used and supported, making it a
preferred choice for 3D Revit
models.
