For example, if you use a grid spacing of one
centimeter, you might use a value of 10 so the
major grid divisions represent one decimeter.

spacing (which is in current units), or enter the
value directly.
For example, if you have units set to centimeters,
you m ig ht make one g rid space equal to 1.000 (one

Perspective V iew Gr id E xtent—Sets the size of the
home grid in the Perspective viewport.
This value is specified in terms of the Grid
Spacing value, and represents the length of
half the grid along an axis. This means that if
Grid Spacing=10.0 and Perspective View Grid
Extent=7, you will have a g rid that is 140 x 140
units in s ize.
