AutoCAD Array Operation strategy

Arrays are a form of AutoCAD replication, and arrays tend to have an advantage over simple replication in the case of regular multiple replications. In AutoCAD, the array is divided into two basic types: rectangular array and annular array.

Rectangular array-Multiple-row and multiple-column replication, and the ability to control the number of rows and columns and the spacing of rows/columns.

Annular array-Specifies the center of the specified ring to determine the radius of the ring (that is, a circle). Around the center for equidistant copying on the circumference. And can control the number of replicated objects and decide whether to rotate the copy.

specific command buttons and menus: We can click the array button on the Modify toolbar. or the menu "modify"-"array". At the command line, enter the command: _array, which finally opens the Array dialog box.

The following are explained separately for the different options for rectangular and annular arrays.

Options and steps for rectangular arrays

When you enter the dialog box, select the rectangular array radio option, as shown in the figure.

dialog box Parameters:

1. Row/column-Specifies the number of rows/columns in the array.

Specifies the number of rows and columns to generate an object for the array. If you specify only one row (column), you must specify multiple columns (rows). If you specify many rows and many columns for this array, AutoCAD may take some time to create a copy.

2. Select objects

Click the Select Object button to temporarily close the Array dialog box and select the object in the drawing area to be patterned.

3. Offset distance and direction

1 in the row Offset and column offset boxes, enter the row offset and column offset.

Note that if negative, the array is represented in the negative direction of the x/y axis. Beginners to distinguish this point, to prevent the wrong array results. As pictured.

Or you can determine the row/column spacing using a method that specifies a distance of two points:

Click the Pick Row offset button and click to specify two points that determine both horizontal and vertical spacing between rows and columns.

Click the pick row offset or pick column offset button to specify both horizontal and vertical spacing, using the same method as the specified point.

The array dialog box is temporarily closed, and the AutoCAD hint specifies two points, the distance and direction between the two points to specify the value of the offset above.

AutoCAD automatically measures the distance between the two points and displays the Row/column offset box.
