Beginning AutoCAD 2010: Exercise Workbook

After completing this lesson, you will be able to:
Understand the Polar Degree Clock
Draw Lines to a specific length and angle
Draw objects using Polar Coordinate Input
Use Dynamic Input
Use Polar Tracking and Polar Snap
In Lesson 9 you learned to control the length and direction of horizontal and vertical lines using Relative Input and Direct Distance Entry. Now you will learn how to control the length and ANGLE of a line using POLAR Coordinate Input ?
Previously when drawing Horizontal and Vertical lines you controlled the direction using a Positive or Negative input. Polar Input is different. The Angle of the line will determine the direction.
For example: If I want to draw a line at a 45 degree angle towards the upper right corner, you would use the angle 45. But if I want to draw a line at a 45 degree angle towards the lower left corner, you would use the angle 225.
You may also use Polar Input for Horizontal and Vertical lines using the angles 0, 90, 180 and 270. No negative input is required.

When entering polar coordinates the first number represents the Distance and the second number represents the Angle. The two numbers are separated by the less than (<) symbol. The input format is: distance < angle
Note: If you are using Dynamic Input (DYN...
