To Constrain the Pending Data Point to a Drawing Plane Axis

  1. Position the pointer near the desired axis. When the pointer is on an axis, a highlighted line is displayed from the drawing plane origin to the pointer location.
  2. Press the Enter key.

    Smart Lock is engaged. Its effect is to constrain the pending data point to the axis.

    You now can constrain the pending data point to a precise distance along the axis by keying in a value, or simply by snapping a tentative point to an element or monument point and accepting the tentative point as the data point location.
