Design and Technology - Admission/Application Essay Example

Lettering in the technical and design field is done by the use of freehand, mechanical and modernized approaches. The essence of lettering design is to have clear and conscience representation. Under freehand lettering is the quickest and most effective in physical applications. There are rules that govern how the lettering is to be done such as drawing a line in the middle of the space where the letter has to be revolved around since in the case of letters, the central line, except in the case of ‘A’ has to appear on that plane.

The lettering using free hand is the most challenging since the hand patterns have to follow design guidelines such s the use of the top-heavy approach to make the letters more stable. In mechanical lettering, the writer makes use of templates to guide their hand motion. The templates used guide the lettering process, though lettering under mechanical means requires that the writer use a single stroke in each case. Auto cad AutoCAD is basically a design and engineering software to represent engineering concepts in form of drawings with the use of computing skills.

The term may also be used to refer to the use of the software in various design fields to put ideas conceptualized in the engineering field in a format where the details involved are easily understood and conceptualized by the audience, which may or may not consist experts in design. AutoCAD is software that is mostly used in computer-aided design and manufacturing where the technical aspects of a design are incorporated in technical representations where all elements of design are assembled.

AutoCAD allows the design teams to represent design ideas in various views that are incorporated in design. The designers are able to represent their ideas in a two-dimensional or three-dimensional method, which allows the real life conceptualization of an idea. The software has the unique capability of converting surfaces into solids, applying different visual styles to the design such that it assumes the situation in which the design is to be incorporated in life. The software allows the user to stimulate the application of an idea in life.

AutoCAD represents the idea of using the software to bring to life the design ideas that a designer has in mind (Little and Clive 321), put it to the test and assess its viability through property and characteristic analysis. AutoCAD is thus a tool in engineering that helps the representation of ideas in the field to both the expert and audiences in other fields. Tolerances Tolerance in engineering design is the actual space that is between a nut and bolt, which is determined by dimension tolerance, which factors in some considerations while determining its settings.

Tolerances are a part of design and assembly since they represent the space that is intentionally allowed in any joinery. The tolerances are defined as fitting, loose or tight. The definition of the tolerances depends on the application as well as the area in which the tolerance is to be used. By providing a space between two elements in joinery, the structural integrity of the object has to be encompassed. With a tight tolerance, the space that is used in the fastener is usually greater than the space where the fastener is to be used.

The tightness of the tolerance is supported by the specific properties of the material
