Drafting Techniques WVEIS Code 1727 This course will introduce students to techniques used in advanced orthographic projection, including dimensioning, sectioning, auxiliary views, revolutions, pattern development and advanced CAD. Standard 1: Apply proper sectioning techniques to fully describe the interior of an object on a drawing. (1727.S.1) Proper Sectioning Techniques Objectives Students will: 1727.1.1 Describe the purpose of a cutting plane and cutting plane line, and properly draw them. 1727.1.2 Draw various ANSI standard section lines used for general sections, steel, concrete, etc. 1727.1.3 Describe the differences between a full, half, revolved, aligned, offset, removed and broken out sections, and use sectioning techniques to complete drawings. Standard 2: Identify and construct pictorial views. (1727.S.2) Pictorial Views Objectives Students will: 1727.2.1 Construct oblique and isometric drawings, including exploded and sectional views. 1727.2.2 Apply standard, horizontal and reverse axes in isometric drawings. 1727.2.3 Draw non-isometric lines, circles arcs, and curved lines. Standard 3: Draw primary and secondary auxiliary views and revolutions. (1727.S.3) Auxiliary Views and Revolutions Objectives Students will: 1727.3.1 Demonstrate knowledge of primary auxiliary views. 1727.3.2 Draw secondary auxiliary views and explain their use. 1727.3.3 Demonstrate knowledge of revolutions and their use. Standard 4: Apply descriptive geometry techniques to solve graphical problems. (1727.S.4) Geometry Techniques Objectives Students will: 1727.4.1 Determine the true length of a line, true view of a plane and the true angle between two planes. 1727.4.2 Determine the intersection between lines, planes, and surfaces. Standard 5: Use proper techniques to draw patterns and developments. (1727.S.5) Patterns and Developments Objectives Students will: 1727.5.1 Develop rectangular prisms, cylinders, pyramids and cones. 1727.5.2 Demonstrate knowledge of transition pieces. 1727.5.3 Apply development techniques to shop patterns. 1 Standard 6: Apply the rules of dimensioning to dimension drawings, using architectural, engineering and metric measurements. (1727.S.6) Rules of Dimensioning Objectives Students will: 1727.6.1 Layout, measure and construct lines with the architectural, engineering and metric scales. 1727.6.2 Describe and apply unidirectional and aligned systems of dimensioning. 1727.6.3 Apply standard dimensioning techniques for a hole, countersink, counter bore and knurling. 1727.6.4 Properly dimension axonometric drawings. Standard 7: Use computer assisted drafting to produce drawings, demonstrating the ability to customize a CAD system. (1727.S.7) Computer Assisted Drafting Objectives Students will: 1727.7.1 Create and use various prototype drawings using custom developed line types, hatch patterns and text styles. 1727.7.2 Modify CAD menu to perform additional and/or new operations. 1727.7.3 Demonstrate the ability to modify operating system files to facilitate CAD operations and load and run a lisp routine.
