What is the 10Technical Drawing and Its Specialized Branches
Architectural drawing
Machine drawing
Sheet and metal drawing
Aeronautical drawing
Structural drawing
Electrical drawing
Fashion design drawing
Map drawing
Marine drawing
Furbiture drawing
This branch
of technical drawing is devoted to the
representation of buildings and similar
structures. The drawing for an
architectural structure includes plans,
elevations, sections, and details sufficient
to define adequately in graphic form.
Architectural drawing
is
a branch of technical drawing used in
machine industries. A machine shop
drawing omits all information concerning
the pattern of preceding processes and
conveys only those needed for
machining
Machine drawing
This drawing
includes all lay-outs and detail drawings
connected with the design and
construction of buildings, bridges,
viaducts, and other similar structures.
Further, structural steel, timber, concrete,
and other building materials
Structural drawing
A branch of
technical drawing used in heating,
ventilating, and air-conditioning
industries. It includes problems involved
in finding the intersections of surfaces
and in developing surfaces of various
kinds into flat patterns and templates
which have many applications in
industries mentioned.
Sheet and metal drawing
This branch of
technical drawing used in electrical
industries. Electrical engineers need the
basic knowledge of drawing as do
chemical engineers and other engineers.
This drawing includes diagrammatic
drawing using conventional symbols for
electrical equipment and conventions
Electrical drawing
s a composite of mechanical,
structural, electrical, and sheet metal
drafting. Here, some deviations made
from each other to establish uniformity as
a single underlying system. A distinctive
feature of aeronautical drafting is the
planning of logical assembly and
installation sequences as well as
designing for maximum strengths for
maximum weight. It used in aircraft
manufacturing
Aeronautical drawing
This drawing deals
with the making of drawings or plans of
boats, ships, and other sea-going
vessels.
Marine drawing
