Engineering Drawing and Design
"Drawing" usually means using drawing instruments, from compasses to computers to bring accuracy to the drawings. The best way to communicate one's ideas is through some form of picture or drawing. This is really true for the engineer. Engineering drawings and design is a credit course designed to further the development of student knowledge and skills in the engineering drawing and design field. An engineering drawing is a type of technical drawing, created within the technical drawing discipline, and used to fully and clearly define requirements for engineering items. Engineering drawings are usually created in accordance with standardised convention for layout, nomenclature, interpretation, appearance (such as type faces and line styles), size, etc. One such standardised convention is called GD&T.
Computer-Aided Drafting (CAD) It is a system used by students to learn or to solve more difficult design and to develop their skills in dimensioning, tolerancing, pictorials, sections, auxiliary views, and intersection and developments. CAD tools and software should be used extensively throughout the course. The standards are aligned with the drafting and design standards in some technical colleges, thus helping to qualify students for advanced placement and to continue their education at the postsecondary level
Its purpose is to accurately and meaningfully capture all the geometric features of a product or a component. The end goal of an engineering drawing is to convey all the required information that will allow a manufacturer to produce that component. Engineering drawings can now be produced using computer technology. Drawings are extracted from three dimensional computer models and can be printed as two dimensional drawings on various media formats it can be color or monochrome. Engineer computer models can also be printed in three dimensional form using special 3D printers.
Common features for engineering drawings -
• Geometry
• Dimensions
• Tolerances
• Material
• Finish
