Comparison between CAD drafting and manual drafting
CAD which is the abbreviation of
‘Computer aided-design’ has brought humongous changes in the functioning of
construction industry. Today the entire Architecture Engineering and
Construction industry has been swept away by CAD technology. Computer aided designs have overtaken the role
of manual drawings which used to be created by architects and engineers.
Earlier, the development of construction drawings used to consume a lot of
time, since there was no powerful tool available to architects and engineers
apart from paper and pencil. So manual drafting was never considered that
accurate because chances of human errors were very high in that.
CAD technology is credited for paradigm
shift in construction industry. With its advent and implementation the
construction industry has grown tremendously.
Data
safety: Previously the manual drawings developed
by architects or engineers were required to be saved in folders, which involved
a great risk of data loss. There used to
be chances wherein folders used to missing. So in such cases engineers had to
create the drawings from the scratch which used to be very tiring. However,
there is no such data related risk involved
in CAD drawings, which can be safely saved in computer folders and can
be accessed any time by design teams.
Digital
3D models can be generated fast: Another most
important advantage of CAD drawings is that 3D models can be generated with
their assistance. These 3D models are developed to represent the design of
multidiscipline building systems and highly crucial building information is
captured in them.
Revisions
or modifications are easy to make: Be
it manual drawings or CAD drawings, the need for revisions and modifications is
always felt by drafters. But in the case of manual drawings modifications are
not at all easy to implement. Sometimes engineers have to create the drawings
from the beginning. However, there is no such problem with CAD drawings, which
can be modified at any point of time by a few mouse clicks. Highly accurate
shop drawings, architectural drawings, structural shop drawings and erection
drawings can be developed by optimizing CAD technology.
CAD
drafting save a lot of time: Compared to manual
drafting, CAD drafting takes considerably
less time. CAD technology is credited for its speed. CAD drafting services are
executed by CAD technicians who are well trained in software applications.
AutoCAD is used by CAD technicians to perform drafting services.
Accuracy:
Accuracy is another important factor due
to which computer aided designs are used worldwide in AEC industry.
