Array

Array

Array

This command is used to create two-dimensional arrays of the selected objects by placing their copies on the specified circle (polar array) or in the nodes of the specified rectangular grid (rectangular array).

The ArrayAssociative command parameter allows you to specify whether arrays will be associative or non-associative.

Elements of an associative array are stored in a single object – an array. In an associative array you can change the number of elements and the distance between them. Such properties of an associative array as the number of elements and distance between them can be changed using the array grips or on the properties toolbar.

After exiting the command non-associative arrays split into independent objects.

The commands to create arrays are located:

MouseOK    Ribbon: Home, Draw Modify

 

MouseOK    Menu: MOdify Array

MouseOK    Toolbar: Modify

 

KeyboardOK Command line

 

ARRAYRECT

ARRAYPOLAR

     

1.    Select the cmomand to create the array.

2.    Select objects to create the array, press Enter.

A preview of a defualt array will be displayed on the screen.

3.    Specify the array parameters.

Data are entered from the command line:

Select a parameter to edit [Associative/Base point/Count/Spacing/COlumn/Rows/Levels/Exit]:

Or with a context entry:

4.    Click Exit to complete the command.

 

KeyboardOK Command line: AR, ARRAYCLASSIC

 

Array command opens the Array dialog box.

There is the  Select objects command in the top corner of the dialog box; it temporarily closes the dialog box whilst selecting the source objects. There is a line showing the number of selected objects - Objects selected below the button.

There is a preview window below the line.

Rectangular array

Parameters:

Rectangular array

Switches on the rectangular array mode.

Example of creating stairs using rectangular array:

     

1.    Create one more stair;

2.    Select created objects;

3.    Specify number of rows - 1;

4.    Specify number of columns - 7;

5.    Specify distance between columns (specify point 1, after that point 2);

6.    Specify angle (specify point 1, after that point 2);
