Relative Coordinates with Auto CAD 10 X 10

Relative Coordinates with Auto. CAD 10 X 10 Units Relative Coordinate points are based from absolute point 4, 4. 1

Applying What You Have Learned • In the first exercise, you drew your initials using the absolute coordinate points. • Perform the same activity again using relative coordinates. • When finished, state which system is the easiest to use and list any problems that you encountered. 2

Using Polar Coordinates • Are input as distance and angle • Polar Coordinates can be absolute or relative • Angle is based on a counter – clockwise direction • Input @5<135 • Point is referenced 5 units at an angle of 135 degrees from the previous point entered 3

Polar Coordinates with Auto. CAD 10 X 10 Units Polar Coordinate angles are based from absolute point 4, 4 (Referenced from 0, 0). 9

Applying What You Learned • Use Auto. CAD to draw your initials using polar coordinates • List any problems that you encountered when using the polar coordinate system for lettering • Using a Venn Diagram compare and contrast the three types of systems used for drawing the 10 x 10 square and the your initials • Ask your instructor for the Venn Diagram to the activity 10
