AutoCAD Relative Coordinate Entry

 Relative is the second of the 3 main methods of Coordinate Entry to accurately draw lines, move, copy, etc. to achieve your desired drawing.  

Relative Coordinate Entry works from the last point entered.  The format used is @X,Y this then move X amount in the x-axis and Y amount in the y-axis.  Note to go to the left or down you would input negative numbers. 

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

Coordinate Type Format Examples
Relative Coordinates

@X,Y

Distance in the X and Y from the the last point.

Specify Next point: @3,27

Specify Next point: @12.337,-0.125

Specify Next point: @-3'8",196'6 1/2"

Relative Coordinate Activity

Draw the shape above using relative coordinate entry

  • Start at point A (you will need to start with Absolute Coordinate Entry) then go to 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 @0, 3 (for "0" to the right in the x-axis and "3" up in the y-axis).
  • To get to point B, input @1, 1.5 (for "1" to the right in the x-axis and "1.5" up in the y-axis).
  • Continue for points D to J. 

Make sure you have your worked reviewed before moving on.
