What Are CAD Drawings | 2D Design | 3D Design |Modeling | Drafting | By CAD Software’s like Pro-e, AutoCAD, Solidworks, CATIA, Unigraphics etc
Computer-aided
design (CAD) is a process that allows computer users to design a
variety of products and geometric shapes on-screen, rather than building
them by hand. Using CAD software, one can create and modify an object
to determine how it will appear and function after it is built. CAD
drawings often include a computer-generated image of the design, as well
as its dimensions, processes, and materials. CAD drawings may be either
two dimensional (2D) or three-dimensional (3D). When an object is drawn
in 3D using CAD, the process is often referred to as rendering or
modeling, while 2D design is often called “drafting.”
CAD
drawings are used in a large number number of industrial and
manufacturing applications. This technology is widely utilized in art
and graphic design, and gives these artists a greater level of design
flexibility than that of other mediums. CAD drawings are also used in
automotive and aerospace design, as well as in the development of
industrial products and equipment. Many special effects used in films
and television rely on computer animation generated with CAD software.
Finally, CAD drawings are a critical component of the construction and
engineering trades.
Before
the invention of CAD, products and building plans were drawn by hand.
This was a laborious and time-intensive process that required a high
number of draftsmen, as well as frequent revisions. With the
introduction of CAD software, engineers and designers were able to
quickly and easily generate and modify drawings. Design firms could hire
fewer staff, and both design and product development cycles were
greatly reduced. CAD software also allowed engineers and designers to
generate their own drawings, rather than to attempt to explain them to a
draftsman, resulting in more accurate design.
Though
CAD drawings have been in use since the 1960s, it wasn’t until the late
1980s and early 1990s that CAD software became a cost-effective option
for many industries. Early versions of the software relied on 2D vector
design, while modern CAD drawings include 3D modeling capabilities.
Today’s modeling software allows designers to not only draw an object,
but to rotate it on an axis, and to see through the object’s walls from
the inside. This modeling capability is particularly useful in
construction and engineering, allowing designers to virtually
“walk-through” a structure and explore different angles.
Most
CAD software is designed only for Windows or Linux operating systems.
Complex CAD drawings may require advanced graphics cards and high levels
of random access memory (RAM), but simpler drawings can be done on
almost any basic computer. CAD software is operated using a traditional
mouse, though some professional designers may supplement this operation
using a digital pen or drawing tablet.
