Basic Drafting Techniques Section 4.1 Getting Ready to Draw Section 4.2 Creating a Drawing 4 Basic Drafting Techniques Section 4.1 Getting Ready to Draw Section 4.2 Creating a Drawing Chapter Objectives • Prepare a drawing sheet for a technical drawing. • Use basic drafting tools and equipment. • Produce a fi nished technical drawing using board-drafting techniques. • Use standard layouts to create and set up a drawing fi le on a CAD system. • Create basic geometry and produce a techni- cal drawing using CAD commands. Checkmate Each type of piece you need for a chess game must go through an entire design process. How many pieces would you need to design for a complete chess set? 88 Todd France/Corbis Drafting Career Michael Graves, Product Designer When you think of a chess set, do you think of mechanical drawing and illustrations? Michael Graves and his team of designers understand the connection. Graves is a world-renowned architect and designer who creates the whimsically designed games, dog food dishes, toasters, teapots, and housewares that are sold in Target stores nationwide. The Graves design team uses CAD software to visualize and design each product. The team presents paper drawings with just a few models. Then 3D drawings are completed and used to manufacture the large assembly machines that stamp out the forms or create the molds for items like toasters and cappuc- cino makers. Academic Skills and Abilities • Math • Computer science • Information systems • Computer programming • Business management skills • Verbal and written communication skills • Organizing and planning skills Career Pathways In addition to a bachelor’s degree in industrial design, commercial and industrial designers usu- ally receive on-the-job training and normally need one to three years of training before they advance to higher level positions. Some experienced designers open their own design fi rms.

Choosing the Drawing Sheet The type of drawing sheet you select Approx. 1” depends on how the fi nal drawing will be used. For example, drawing paper is appropri- ate for short-term use, while polyester fi lm is better for long-term use. The size of the sheet is determined by the size and complexity of the drawing. It is often useful to make a freehand sketch of the views and notes before proceeding to do the fi nal instrument drawing. Except in rare cases, standard drawing-sheet sizes should be used.

  • Caliper Gauge
    Caliper Gauge As to internal caliper gauge IM-880 series, the distance between contact points facing outside is firstly set at standard dimension with ring gauge or micrometer. Then, it is measured by inserting contact point into internal dimension part to be measured after its outer dial of which moves together with rotated bezel is set at “0”. The displacement of indicator from “0” point of outer dial is to be measured at that time. The value adding to the read displacement to standard dimension or deducting it from standard dimension is the dimension of internal diameter. This series attaches spare contact point which cam set accurate dimension corresponding to size of internal dimension. External caliper gauge is opposite, namely reading the value by holding work piece with 2 contact points facing outside. Internal Dial Caliper Gauge • These gauges are designed for use in measuring deep internal diameter of bores of castings etc, and for internal reading in fabrications. Clearance has been provided for use in recessed bores. The convenient retraction lever allows one-hand operation.

  • 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.

With this method, you do not have to reset the system to zero after turning it off and then turning it on. The position information recorded on the scale is read every time. The following three types of absolute encoders are available: electrostatic capacitance model, electromagnetic induction model and model combining the electrostatic capacitance and optical methods. These encoders are widely used in a variety of measuring instruments as the length measuring system that can generate highly reliable measurement data. Advantages: 1. No count error occurs even if you move the slider or spindle extremely rapidly. 2. You do not have to reset the system to zero when turning on the system after turning it off*1.

  • 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.
