CHAPTER 6 Technical Drawing Tools Based on Technical Graphics Communication by Bertoline, Et Al Dr Simin Nasseri, Southern Polytechnic State University
CHAPTER 6 Technical Drawing Tools Based on Technical Graphics Communication by Bertoline, et al Dr Simin Nasseri, Southern Polytechnic State University OBJECTIVES After completing this chapter, you will be able to: 1. Identify the important parts of a CAD system used to create technical drawings. 2. Define the important terms related to CAD systems. 3. Identify the important traditional tools used to create technical drawings. 4. Define the important terms related to traditional tools. 5. Use traditional tools and CAD to draw lines, circles, arcs, and curves. 6. Use scales, dividers, and CAD to measure and scale drawings. 7. Identify standard metric, U.S., and architectural drawing sheet sizes. 8. Identify standard pencil grades, and identify those most commonly used for technical drawings. 9. Identify the types and thicknesses of the various lines in the alphabet of lines. 10. Use traditional tools and CAD to erase parts of a drawing. INTRODUCTION Just as the graphics language has evolved over the years into a sophisticated set of standards and conventions, so have the tools used to graphically communicate technical ideas. Tools are used to produce three basic types of drawings: freehand sketches, instrument drawings, and computer drawings and models. 6.1 TECHNICAL DRAWING TOOLS Computer-aided design/drafting (CAD) is computer software and related computer hardware that supplements or replaces traditional hand tools in creating models and technical drawings. Engineers use computer-aided design/computer-aided manufacturing (CAD/CAM) in the design and production processes. 6.2 COMPUTER-AIDED DRAWING TOOLS A CAD system consists of hardware devices used in combination with specific software. -
Electronic Theodolites, Electronic Tacheometers, Total Stations and Data Collectors
ELECTRONIC THEODOLITES, ELECTRONIC TACHEOMETERS, TOTAL STATIONS & DATA COLLECTORS Electronic theodolites operate in a manner similar to that of optical theodolites or even vernier transits. Angle readouts are to 1 second, with accuracies from 0.5 to 10 seconds; digital readouts (LED or LCD) eliminate the guessing and interpolation of circle and micrometer settings associated with scale and micrometer theodolites. Electronic theodolites have zero-set buttons for quick instrument orientation after the backsight has been set; horizontal angles can be turned left or right, and repeat-angle averaging is available on some models. Some models also include horizontal and vertical collimation corrections, and vertical circle readings referenced to zenith, horizon, or percent slope format. The most significant characteristic of electronic theodolites is their ability to be interfaced electronically to data collectors and to computers, permitting a quick, error-free transfer of field data to the computer. Electronic tachometers (ETI) combine electronic theodolites with EDM instruments both of which are interfaced to a data collector. In this configuration it is called a total station. These electronic tachometers can read and record horizontal and vertical angles together with slope distances. The microprocessors in the ETI can perform a variety of mathematical operations (e.g., averaging multiple angle measurements; averaging multiple distance measurements; X, Y, Z coordinate determination; remote object elevations (heights of sighted features); distances between remote points; adjustments for atmospheric conditions; and so on. In addition, attribute data such as point numbers, point codes, and comments can be included with the recorded field measurements. The data collector is usually a hand-held device connected by cable to the tachometer, although some manufacturers have the data collector included as an integral component of the instrument. -
