Unit

Contains controls that are used to adjust Unit Lock and a related setting.

Unit Lock

If on, each data point is forced to lie at coordinates that are multiples, in each dimension, of the (Unit) Distance. Unit Lock works with the imaginary unit grid in the same manner Grid Lock works with the real grid.

For example, if Unit Distance is 0:1, points in the imaginary unit grid are spaced one sub-unit apart.

Key-in: LOCK UNIT [OFF | ON | TOGGLE]

Conflicts between Unit Lock and Axis Lock are resolved as follows: If the (Axis) Start Angle and (Axis) Increment are such that the imaginary unit grid does not align with an axis, Axis Lock nullifies Unit Lock. If the axis anchor point is off the unit grid and the Axis Start Angle and Axis Increment are such that grid points do not lie on an axis, Unit Lock is applied, followed by Axis Lock.

Grid Lock nullifies Unit Lock if the distance between grid points exceeds Unit Distance.

(Unit) Distance

Sets the distance, in working units, between points in the imaginary grid used by Unit Lock. Unit Distance takes effect only when Unit Lock is on.
