Planters Restricted use only 12, 1 Definitions Assembly Drawing What is an assembly drawing and why do we need them? An assembly drawing is a drawing of an entire machine or system with all of its components located and identified.

We need to know how to put the machine together. Technical Drawing Lecture Essay Words 2 Pages Drawing is a graphic representation of real thing an idea or proposed design. Drafting began when the early people started drawing Objects on earth sand and stone 3. Drafting accurate manual or computerized presentation Of working plans and detailed drawings.

CAD stands for computer aided drawing 5. Lettering is a very important part of drawing 6. Alphabet of lines examples of these are object line, hidden line etc. Dimensioning indicates measurement of an object or drawing 8.

Center lines are broken Kinds of Oblique Drawing Essay Words 3 Pages Oblique drawings are designed to show a three dimensional view of an object.

The width of the object will still be drawn as a horizontal line, but the depth can be drawn back at any angle. You can choose the best angle to make the drawing look the best. There are three types of oblique, cavalier, normal, and cabinet oblique.

Cabinet drawings are when the you cut the depth in halt. Cavalier drawings are when you keep the depth the full measurement. The following guide will present to you the Technical, Architectural and Engineering Drawing Tools Essay Words 3 Pages A T-square is a technical drawing instrument used by draftsmen primarily as a guide for drawing horizontal lines on a drafting table.

It may also guide a set square to draw vertical or diagonal lines. Its name comes from its resemblance to the letter T. T-squares come in varying sizes, common lengths being 18 inches mm , 24 inches mm , 30 inches mm , 36 inches mm and 42 inches 1 , mm Ames Lettering Instrument If you have many lines of lettering to do, you will find a lettering instrument, such as the Ames lettering instrument, The accuracy and neatness of engineering drawing depends on the quality of the instruments used.

With good instruments, the drawing can be prepared easily, quickly and accurately. Therefore, the knowledge of different drawing instruments and materials, methods of using them and the preparatory works to be completed before commencing the drawing is very important. Else Of Engineering Instruments 1. Drawing Board. A drawing board with its working surface upward. Else as a base for drafting on paper. Drawing Sheet - The drawing is frequently made in pencil on Engineering drawing Essay Words 15 Pages The goal of this paper is to study the importance to drawing both formal drafting and informal sketching in the process of mechanical design.

This goal can he extended to state that we intend to show the necessary to drawing during all the developmental stages of a mechanical design. Through the information presented here, the requirements for future computer aided design tools, graphics education, and further studies will be developed. All mechanical engineers are taught drafting. Thus, most engineers are skilled at making and interpreting these formal mechanical drawings.

These drawings are representations Of a final design the end product Perspective Drawing Essay Words 4 Pages In the tutorial lessons that follow this page, you will be given the tools needed to map out a perspective grid for any s-dimensional situation. From this grid, you will be able to create realistic three dimensional drawings from flat or "Off Angle" reference.

Sections and Section views on Engineering Drawings

A Section or cross section is a view generated from a part or assembly on a cutting plane or multiple cutting planes that reveals the outlines on the inside or assembly fits. Sections normally comprise of two parts, firstly the Section Cut indicator with identification. This indicator will then generate a Section view. Section Cut indicators Section cut indicators identifies the plane where, how and on which planes the section cut is made. The line that indicates the plane where the cut is made is called the section line. Arrows indicate the direction of view.

Engineering Drawing – Dimensioning and Sectioning Essay

Sectioning or crosshatching lines Last Updated on Thu, 16 Apr Engineering Drawing When you go to a museum, you often see artefacts that have been cut up. For example, to illustrate how a petrol engine works, the cylinder block can be cut in half and the cut faces are invariably painted red. In engineering drawing , cross-hatching is the equivalent of painting something red. It is used to show the internal details of parts which otherwise would become too complex to show or dimension.
