Lesson 5 - Using Coordinate Entry to Draw AutoCAD

Lesson Summary:

This lesson will give you practice drawing in AutoCAD using a variety of methods for entering precise data.  First you will review of the Cartesian Coordinate system that is the underlying system of recording data in AutoCAD.  Next, you will learn how to enter data using Absolute Coordinates, Relative Coordinates and Relative Polar Coordinates.  Using this information, you will complete to project Drawing to practice applying these drawing methods.

Learning Objectives: 

When you have completed this lesson, you will be able to:

  1. Explain how the Cartesian Coordinate system relates to the coordinate system used by AutoCAD.
  2. Use Absolute Coordinate values to enter point locations in AutoCAD.
  3. Draw a assigned object in AutoCAD by entering the Absolute Coordinate values of the endpoint of each line.
  4. Use Relative Coordinate values to enter point locations in AutoCAD.
  5. Explain the default Polar system used by AutoCAD for measuring and drawing angles.
  6. Use Relative Polar Entry to input point locations. This includes input of both a distant and angle to designate a point relative to a current location.
  7. Explain the relationship of the WCS icon (World Coordinate System) to the AutoCAD coordinate system. Explain the difference between the WCS and the UCS (User Coordinate System).
  8. Draw an assigned object by entering the Relative Polar Coordinates for all of the lines.
