How to Draw a Grid or Graph

Spirals

There are two types of  spiral , symmetrical and logarithmic. Symmetrical spirals expand evenly so that the distance between each revolution is equal. Logarithmicspirals expand with increasingly larger distances between revolutions. You can set the rate by which a logarithmic spiral expands outward.

    

How To draw a spiral

Open the Object flyout

click the Spiral tool

Type a value in the Spiral revolutions box on the property bar.

On the property bar, click one of the following buttons:

• Symmetrical spiral

• Logarithmic spiral

If you want to change the amount by which the spiral expands as it moves outward, move the Spiral expansion slider.

Drag diagonally in the drawing window until the spiral is the required size.

You can draw a spiral from its center outward by holding down Shift as you drag.

You can also draw a spiral with even horizontal and vertical dimensions by holding down Ctrl as you drag.

Drawing grids

•     Open the Object flyout

•      click the Graph paper tool                         .

•      Type values in the top and bottom portions of the Graph paper columns and rows box          on the property bar.

•      The value you type in the top portion specifies the number of columns; the value you type in the bottom portion specifies the number of rows.

•      Point to where you want the grid to appear.

•      Drag diagonally to draw the grid.

•      If you want to draw the grid from its center point outward, hold down Shift as you drag; if you want to draw a grid with square cells, hold down Ctrl as you drag.

To ungroup a grid

•      Select a grid by using the Pick tool
