intro Flashcards
Designers generally use _________ to represent the object which they are designing, and to communicate the design to others.
drawings
the importance in computer-aided design (CAD) of the production of visual images by computer,
computer graphics
a technique where engineering drawings are produced with the assistance of a computer and, as with manual drawing, is only the graphical means of representing a design
Computer-aided drafting (CAD
a process of preparing a drawing of an object on the screen of a computer.
Computer Aided Drafting
The use of CAD process provides enhanced graphics capabilities which allows any designer to:
Conceptualize his ideas
Modify the design very easily
Perform animation
Make design calculations
Use colors, fonts and other aesthetic features
Layout drawings, part drawings, sub-assemblies, assemblies
Aerospace
Process schematics, process plant layout drawings
Chemical
: Mapping, Building drawing, Structural design, Town planning, Interior decorations, Multi-storey complex, Surveying etc.
Civil, Architecture
Circuit layout, Panel design, Control system etc.
Electrical
Schematic diagrams of PCs, ICs etc.
Electronics
Manufacturing plant layout drawings, subassemblies, assemblies
Industrial and Manufacturing
Design of machine elements, CNC machine tools, Robots etc.
- Mechanical:
: Kinematics, Hydraulics, Steering etc.
- Automotive
The implementation of the CAD system provides variety of benefits to the industries in design and production as given below:
Improved productivity in drafting
Shorter preparation time for drawing
Reduced man power requirement
Customer modifications in drawing are easier
More efficient operation in drafting
Low wastage in drafting
Minimized transcription errors in drawing
Improved accuracy of drawing
Assistance in preparation of documentation
Better designs can be evolved
Revisions are possible
Colors can be used to customize the product
Production of orthographic projections with dimensions and tolerances
Hatching of all sections with different filling patterns
Preparation of assembly or sub assembly drawings
Preparation of part list
Machining and tolerance symbols at the required surfaces
Hydraulic and pneumatic circuit diagrams with symbols
Printing can be done to any scale
the representation of an object in the single-view format which shows two of the three object dimensions or the multi-view format where each view reveals two dimensions.
Two-dimensional (2D) computer drawing
the database includes just two values for each represented coordinate of the object. It can also be a pictorial representation if the database contains X, Y coordinates only.
