Beginning Mechanical Design

DRF 105

Beginning Mechanical Design

DRF 105

Course Description

Provides instruction and practice to develop skill in spatial visualization, sketching, multiview instrument drawing, section views, design concept presentation, pictorial drawing, and American National Standards Institute (ANSI) conventional drafting and dimensioning standards. Credit may be earned in DRF 104 or DRF 105 but not both. (15-75)

Outcomes and Objectives

Objectives:

  • Construct and apply standard mechanical lettering.
  • Construct and apply standard mechanical linetypes to the construction of geometrical figures

Use standard drafting instruments and pencils to letter and construct single views of mechanical components.

Objectives:

  • Construct and apply standard mechanical lettering to mechanical components.
  • Construct and apply standard mechanical linetypes to the construction drawings of single mechanical components.

Use standard drafting instruments and pencils to letter and construct multi-views of single mechanical components.

Objectives:

  • Construct and apply standard mechanical lettering to mechanical components.
  • Construct and apply standard mechanical linetypes to multi-view drawings of single mechanical components.
  • Apply the principles of orthographic projection to construct a multi-drawing of single mechanical components, such as tooling, jigs, fixturing, injection molds, etc.
