Drafting TechniquesWVEIS 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:

1727.1.1Describe the purpose of a cutting plane and cutting plane line, and properly draw them.

1727.1.2Draw various ANSI standard section lines used for general sections, steel, concrete, etc.

1727.1.3Describe 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:

1727.2.1Construct oblique and isometric drawings, including exploded and sectional views.

1727.2.2Apply standard, horizontal and reverse axes in isometric drawings.

1727.2.3Draw 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:

1727.3.1Demonstrate knowledge of primary auxiliary views.

1727.3.2Draw secondary auxiliary views and explain their use.

1727.3.3Demonstrate knowledge of revolutions and their use.

Standard 4: Apply descriptive geometry techniques to solve graphical problems. (1727.S.4)

Geometry Techniques Objectives

Students will:

1727.4.1Determine the true length of a line, true view of a plane and the true angle between two planes.

1727.4.2Determine 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:

1727.5.1Develop rectangular prisms, cylinders, pyramids and cones.

1727.5.2Demonstrate knowledge of transition pieces.

1727.5.3Apply development techniques to shop patterns.

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:

1727.6.1Layout, measure and construct lines with the architectural, engineering and metric scales.

1727.6.2Describe and apply unidirectional and aligned systems of dimensioning.

1727.6.3Apply standard dimensioning techniques for a hole, countersink, counter bore and knurling.

1727.6.4Properly 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:

1727.7.1Create and use various prototype drawings using custom developed line types, hatch patterns and text styles.

1727.7.2Modify CAD menu to perform additional and/or new operations.

1727.7.3Demonstrate the ability to modify operating system files to facilitate CAD operations and load and run a lisp routine.
