2D Arrays

CAD drafting 2D Arrays 0 Command line: AR, ARRAYCLASSIC

 

Array command opens the Array dialog box.

There is the CAD software 2D Arrays 1 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.

Rows:

Number of rows.

Columns:

Number of columns.

Offset distance and direction

Row offset:

Distance between rows.

Column offset:

Distance between columns.

Angle of array:

Field to enter an angle of array.

Buttons:

Button temporarily closes the dialog box to specify the distance or an angle on the screen.

CAD drafting 2D Arrays 3

Specify the distance between rows on the screen.

CAD software 2D Arrays 4

Specify the distance between columns on the screen.

CAD drawing 2D Arrays 5

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);
