Selecting a shape tool changes the available options in the options bar. To access shape tool options, click the inverted arrow next to the shape button in the options bar.

Arrowheads Start And End

Adds arrowheads to a line. Select the Line tool and then select Start to add an arrow to the beginning of the line; select End to add an arrow to the end of the line. Select both options to add arrows to both ends. The shape options appear in the pop-up dialog box. Enter values for Width and Length to specify the proportions of the arrowhead as a percentage of the line width (10% to 1000% for Width, and 10% to 5000% for Length). Enter a value for the concavity of the arrowhead (from –50% to +50%). The concavity value defines the amount of curvature on the widest part of the arrowhead, where the arrowhead meets the line.

Note: You can also edit an arrowhead directly using the vector selection and drawing tools.

Circle

Constrains an ellipse to a circle.

Defined Proportions

Renders a custom shape based on the proportions with which it was created.

Defined Size

Renders a custom shape based on the size at which it was created.

Fixed Size

Renders a rectangle, rounded rectangle, ellipse, or custom shape as a fixed shape based on the values you enter in the Width and Height text boxes.

From Center

Renders a rectangle, rounded rectangle, ellipse, or custom shape from the center.

Indent Sides By

Renders a polygon as a star. Enter a percentage in the text box to specify the portion of the star’s radius taken up by the points. A 50% setting creates points that are half the total radius of the star; a larger value creates sharper, thinner points; a smaller value creates fuller points.

Proportional

Renders a rectangle, rounded rectangle, or ellipse as a proportional shape based on the values you enter in the Width and Height text boxes.

Radius

For rounded rectangles, specifies the corner radius. For polygons, specifies the distance from the center of a polygon to the outer points.

Sides

Specifies the number of sides in a polygon.

Smooth Corners or Smooth Indents

Renders a polygon with smooth corners or indents.

Snap To Pixels

Snaps edges of a rectangle or rounded rectangle to the pixel boundaries.

Square

Constrains a rectangle or rounded rectangle to a square.

Unconstrained

Lets you set the width and height of a rectangle, rounded rectangle, ellipse, or custom shape by dragging.

Weight

Determines the width, in pixels, of a line.
