Array Dialog Box

Array Dialog Box

Creates multiple copies of objects in a rectangular or polar alignment.

Access Methods

ARRAYCLASSIC

Use the Rectangular Array option to create an array of rows and columns of copies
of the selected object. Use the Polar Array option to create an array by copying the
selected objects around a center point.

NOTE:This legacy dialog box does not support array associativity or path arrays. To use
these features, available on the ribbon, use the ARRAY command.

List of Options

The following options are displayed.

Rectangular Array

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

NOTE: If you specify a large number of rows and columns for the array, it might take a
while to create the copies. By default, the maximum number of array elements that
you can generate in one command is 100,000. The limit is set by the MAXARRAY setting
in the registry. To reset the limit to 200,000, for example, enter (setenv “MaxArray” “200000”) at the Command prompt. (MAXARRAY is not available in AutoCAD LT.)

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.

NOTE:If you select multiple objects, the base point of the last selected object is used
to construct the array.

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.
