Presentation Transcript

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

  2. 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.

  3. 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 unitsat an angle of 135 degreesfrom the previous point entered

  4. Plot Polar Points in Quadrant 1 Y Axis 12 10 8 6 4,4 4 2 X Axis 0 14 2 12 16 6 8 4 10

  5. Plotting Polar Points in Quadrant 1 Y Axis @10<90 12 Remember!!! The point is relative to the previous point that was inputted. 10 8 6 4,4 4 2 X Axis 0 14 2 12 16 6 8 4 10

  6. Plotting Polar Points in Quadrant 1 Y Axis @10<0 12 10 Remember!!! The point is relative to the previous point that was inputted. 8 6 4,4 4 2 X Axis 0 14 2 12 16 6 8 4 10

  7. Plotting Polar Points in Quadrant 1 Y Axis 12 Remember!!! The point is relative to the previous point that was inputted. 10 8 6 4,4 4 @10<270 2 X Axis 0 14 2 12 16 6 8 4 10

  8. Plotting Polar Points in Quadrant 1 Y Axis Remember!!! The point is relative to the previous point that was inputted. 12 10 8 6 4,4 4 2 @10<180 X Axis 0 14 2 12 16 6 8 4 10

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

  10. Applying What You Learned Use AutoCAD 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
