Basic Drawing Equipment Worksheet
Drawing Equipment Technical drawings, graphic images and sketches can be created using a variety of instruments, ranging from traditional tools such as pencils, compasses, rulers and a variety of triangles as well as by computer. Drawing tools are used to make accurate and legible drawings and models. Whilst the computer can be used for most drawing and modeling requirements today, traditional drawing instruments such as those mentioned above are still important very important, particularly for freehand sketching and experimenting with shapes and lines. When drawing, sketching or attempting basic graphics work the pieces of equipment shown below are very useful and often essential. A protractor is used to measure angles. A typical protractor is a semi- circular piece of plastic with 180 degrees printed around its curve. This piece of equipment is not only used in graphics for constructing accurate drawings but is also used in subjects like Mathematics. Also available for graphics is a full circle protractor which can be used to accurately measure angles greater than 180 degrees. A Mechanical pencil (sometimes known as a clutch pencil or refillable pencil) are used in drawings such as Orthogonal or Isometric drawings as they provide a very constant line thickness. The pencils come in a number of line thicknesses with the more common being 0.35, 0.5, and 0.7. These pencils can be very expensive as are the refills. A compass (or pair of compasses) is a technical drawing instrument that can be used for drawing circles or arcs. As dividers, they can also be used as tools to measure distances, in particular on maps. -

I Engineering Drawing
Chapter - I Engineering Drawing Introduction A picture is worth saying a thousand words; hence drawings are used to visually communicate ideas, thoughts, and designs. Drawings drawn by an engineer for engineering purposes is Engineering Drawing. Drawing is the Universal Graphical Language of Engineers, spoken, read and written in its own way. Engineers must have perfect drawing skills and excellent working knowledge of engineering concepts. An inaccurate drawing may misguide the workman and ultimately affect the production. Objectives In this, the first session, you'll be looking at drawing instruments and the typical accessories used in drawing. On completion of the session, you should be able to: •= Identify various types of drawing instruments and their uses. •= Classify drawing sheets and the different grades of drawing pencils. •= Draw the layout and title block on a drawing sheet. •= Use the lettering and dimensioning techniques in common practice. Drawing Instruments The Drawing Board The D2 or D3 drawing boards are usually used in polytechnics and engineering colleges. Drawing boards are made of well-seasoned softwood such as Oak or Pine. The standard sizes of drawing boards as per BIS (1444-1977) are given in the table. The Drawing Sheet The standard sizes of drawing sheets as per BIS (10711-1983) are given in the table. The ratio of the width of a drawing sheet to its length is 1: A2. The drawing sheet should be tough and strong and its fibers should not disintegrate when an eraser is used on its surface. Minidrafter: A minidrafter is a device with two scales set at right angles to each other. -
