Use the grid tools to quickly draw
rectangular and polar grids. The Rectangular Grid tool creates rectangular
grids of a specified size with a specified number of dividers. The
Polar Grid tool creates concentric circles of a specified size and
a specified number of dividers.
Draw rectangular grids
Select the Rectangular Grid tool .
Do
one of the following:
Drag
until the grid is the desired size.
Click
to set the grid’s reference point. In the dialog box, click a square
on the reference point locator to
determine the point from which the grid is drawn. Then set any of
the following options, and click OK.
Default Size
Specifies
the width and height of the entire grid.
Horizontal Dividers
Specifies
the number of horizontal dividers you want to appear between the
top and bottom of the grid. The Skew value determines how the horizontal
dividers are weighted toward the top or bottom of the grid.
Vertical Dividers
Specifies
the number of dividers you want to appear between the left and right
sides of the grid. The Skew value determines how the vertical dividers
are weighted to the left or right side.
Use Outside Rectangle As Frame
Replaces
the top, bottom, left, and right segments with a separate rectangular
object.
Fill Grid
Fills
the grid with the current fill color (otherwise, the fill is set
to none).
Draw circular (polar) grids
Select the Polar Grid tool .
Do
one of the following:
Drag
until the grid is the desired size.
Click
to set the grid’s reference point. In the dialog box, click a square
on the reference point locator to
determine the point from which the grid is drawn. Then set any of
the following options, and click OK.
Default Size
Specifies
the width and height of the entire grid.
Concentric Dividers
Specifies
the number of circular concentric dividers you want to appear in
the grid. The Skew value determines how the concentric dividers
are weighted toward the inside or outside of the grid.
Radial Dividers
Specifies
the number of radial dividers you want to appear between the center
and the circumference of the grid. The Skew value determines how
the radial dividers are weighted counterclockwise or clockwise on
the grid.
Create Compound Path From Ellipses
Converts
the concentric circles into separate compound paths and fill every
other circle.
Fill Grid
Fills
the grid with the current fill color (otherwise, the fill is set
to none).
