2. Introduction In this lesson, students will learn how to accurately and neatly to scale complete a revolve drawing of a nose cone. Copyright © Texas Education Agency, 2012. All rights reserved.

3. Lesson Objectives 1. Define terms associated with the lesson: height, width, axis, planes. 2. Identify views and dimensions. 3. Lay out overall shape in 2-D and convert to a solid. 4. Identify and understand a polyline. Copyright © Texas Education Agency, 2012. All rights reserved.

4. Storyboard - to revolve an object  Construct all segments to the shape of choice. (In this case a nose cone.)  Close all ends to line segments.  Revolve the object around an axis.  Choose the axis line from top to bottom of object.  Choose the revolutions ( 360 degrees ) full circle.  Enter and the object will revolve.
