AutoCAD Polar Coordinate Entry

Polar is the third and most used of the 3 main methods of Coordinate Entry to accurately draw lines, move, copy, etc. to achieve your desired drawing.

Polar Coordinate Entry works from the last point entered.  The format used is @Distance < Angle this then moves the Distance specified at the Angle specified.

Polar Coordinate Angles

To work in the Polar Coordinate system chose what you wish to draw (line, circle, rectangle, etc.) or modify (copy, move, rotate, etc.) and then type in the Polar Coordinate you wish to go to.  Below is an example of the Polar Coordinate Entry.

Coordinate Type Format Examples

@Distance<Angle

Distance and Angle from the last point

Specify Next point: @5<27

Specify Next point: @5'6"<225

Specify Next point: @7<30:30:30

Polar Coordinate Activity

Draw the shape above using polar coordinate entry

  • Start at point A (you will need to start with absolute coordinate entry) then go to point B, C, etc.
  • First select LINE tool, then for point A type in the coordinate 2, 2 at the command prompt.
  • Hit the F12 key to turn off Dynamic Input if input boxes such as the following example, appear while drawing lines.

 

  • To get to point B, input @2.1<140 (for "2.1" Distance at an angle of 140°).
  • To get to point C, input @2<90 (for "2" Distance at an angle of 90°).
  • Continue for points D to J 

Make sure you have your worked reviewed before moving on.
