# Descriptive Geometry

SKDR 121

## Course Description

Prerequisite: SKDR 111. Topics include orthographic projections, primary auxiliary views and lines, planes, successive auxiliary views, piercing points, intersection of planes, and angle between planes. (45)

## Outcomes and Objectives

### The student will be able to draw primary and auxiliary views of elements using descriptive geometry techniques.

#### Objectives:

• Demonstrate the theory used to create the primary views of a three dimensional element.
• Demonstrate the system of labeling and identification of points, lines, and planes as used in descriptive geometry.
• Demonstrate the concepts of spatial projection, spatial direction, and spatial measurement.

### The student will be able to draw the three dimensional relationship between vectors, lines, and planes their intersections, tangencies, parallelism, perpendicularity, and angles.

#### Objectives:

• Demonstrate the concepts of analyzing spatial problems using lines, planes, and revolution and draw their solution.
• Demonstrate the skills necessary to create on paper the projections of the primary and multiple auxiliary views of three dimensional elements.
• Improve their visualization of objects and ability to draw in three dimensional space.
