In absolute coordinate entry, each point is measured from

  • A.the origin of the coordinate system
  • B.the last point entered
  • C.the centre of the current view
  • D.the lower left corner of the plotted paper sheet

Answer: A

Correct answer: the origin of the coordinate system

Absolute entry gives the point’s position in the drawing’s own coordinate frame, measured from the origin regardless of where the cursor or the last point happens to be. Relative entry measures from the previous point instead, and confusing the two is the commonest way of placing geometry a long way from where it was meant to go.
