Rectangular Array

Creates an array of rows and columns of copies of the selected object.

Rows

Specifies the number of rows in the array.

If you specify one row, you must specify more than one column.

Columns

Specifies the number of columns in the array.

If you specify one column, you must specify more than one row.

Offset Distance and Direction

Provides a space for you to specify the distance and direction of the array’s offset.

• Row Offset. Specifies the distance (in units) between rows. To add rows downward, specify a negative
  value. To specify row spacing with the pointing device, use the Pick Both Offsets
  button or the Pick Row Offset button.
• Column Offset. Specifies the distance (in units) between columns. To add columns to the left, specify
  a negative value. To specify column spacing with the pointing device, use the Pick
  Both Offsets button or the Pick Column Offset button.
• Angle of Array. Specifies the angle of rotation. This angle is normally 0, so the rows and columns
  are orthogonal with respect to the X and Y drawing axes of the current UCS. You can
  change the measurement conventions for angles using UNITS. The ANGBASE and ANGDIR
  system variables affect the angle of arrays.
• Pick Both Offsets. Temporarily closes the Array dialog box so that you can use the pointing device to
  set the row and column spacing by specifying two diagonal corners of a rectangle.

• Pick Row Offset. Temporarily closes the Array dialog box so that you can use the pointing device to
  specify the distance between rows. You are prompted to specify two points and the
  program uses the distance and direction between the points to specify the value in
  Row Offset.
• Pick Column Offset. Temporarily closes the Array dialog box so that you can use the pointing device to
  specify the distance between columns. You are prompted to specify two points and the
  program uses the distance and direction between the points to specify the value in
  Column Offset.
• Pick Angle of Array. Temporarily closes the Array dialog box so that you can specify the angle of rotation
  by entering a value or using the pointing device to specify two points. You can change
  the measurement conventions for angles using UNITS. The ANGBASE and ANGDIR system
  variables affect the angle of arrays.

Polar Array

Creates an array by copying the selected objects around a specified center point.

Center Point

Specifies the center point of the polar array. Enter coordinate values for X and Y, or choose Pick Center Point to use the pointing device to specify the location.

Pick Center Point

Temporarily closes the Array dialog box so that you can use the pointing device to
specify the center point in the drawing area.

Method and Values

Specifies the method and values used to position objects in the polar array.

• Method. Sets the method used to position objects. This setting controls which of the Method
  and Value fields are available for specifying values. For example, if the method is
  Total Number of Items & Angle to Fill, the related fields are available for specifying
  values; the Angle Between Items field is not available.
• Total Number of Items. Sets the number of objects that appear in the resultant array. The default value is
  4.
• Angle to Fill. Sets the size of the array by defining the included angle between the base points
  of the first and last elements in the array. A positive value specifies counterclockwise
  rotation. A negative value specifies clockwise rotation. The default value is 360.
  A value of 0 is not permitted.
• Angle Between Items. Sets the included angle between items based on the base points of the arrayed objects
  and the center of the array. Enter a positive value. The default direction value is
  90.
  NOTE:You can choose the Pick buttons and use the pointing device to specify the values
  for Angle to Fill and Angle Between Items.

• Pick Angle to Fill. Temporarily closes the Array dialog box so that you can define the included angle
  between the base points of the first and last elements in the array. You are prompted
  to select a point relative to another point in the drawing area.
• Pick Angle Between Items. Temporarily closes the Array dialog box so that you can define the included angle
  between the base points of the arrayed objects and the center of the array. You are
  prompted to select a point relative to another point in the drawing area.

Rotate Items as Copied

Rotates the items in the array, as shown in the preview area.

More/Less

Turns the display of additional options in the Array dialog box on and off. When you
choose More, additional options are displayed, and the name of this button changes
to Less.

Object Base Point

Specifies a new reference (base) point relative to the selected objects that will
remain at a constant distance from the center point of the array as the objects are
arrayed. The configuration of the polar array is based on the distance from the array’s
center point to a reference (base) point on the last object selected. The point used
depends on the type of object, as shown in the following table.

Base Point Settings by Object

Object type	Default base point
Arc, circle, ellipse	Center point
Polygon, rectangle	First corner
Donut, line, polyline, 3D polyline, ray, spline	Starting point
Block, multiline text, single-line text	Insertion point
Construction lines	Midpoint
Region	Grip point

Set to Object’s Default

Uses the default base point of the object to position the arrayed object. To manually
set the base point, clear this option.

Base Point

Sets a new X and Y base point coordinate. Choose Pick Base Point to temporarily close the dialog box
and specify a point. After you specify a point, the Array dialog box is redisplayed.

NOTE:To avoid unexpected results, set the base point manually if you are constructing a
polar array and do not want to rotate the objects.

Select Objects

Specifies the objects used to construct the array. You can select objects before or
after the Array dialog box is displayed. To select objects when the Array dialog box
is displayed, choose Select Objects. The dialog box temporarily closes. When you finish
selecting objects, press Enter. The Array dialog box is redisplayed, and the number
of objects selected is shown below the Select Objects button.

Preview Area

Shows a preview image of the array based on the current settings in the dialog box.
The preview image is dynamically updated when you move to another field after changing
a setting.

Preview

Closes the Array dialog box and displays the array in the current drawing.
