Auto Shape extension for Adobe Fireworks CS5
Aaron Beall 2011 - fireworks.abeall.com
Version 1.4.1

Description:

A precise arc drawing tool, defined from the following parameters: origin, begin angle, end angle, radius, and direction (clockwise or conterclockwise.)

When drawing an arc with the arc tool:

• Mouse down defines the origin.
• Mouse drag defines the radius and the begin angle.
• Hold Shift while dragging to lock the radius.
• Hold Ctrl/Cmd to adjust the end angle.
• Hold Alt/Opt to reverse the arc direction.

Once you have drawn the arc, you can modify the parameters by dragging the control points, or click them to input a precise numeric value.

• Hold Shift while dragging the begin/end angle to snap to 45 degree increments.
• Hold Alt/Opt while dragging the begin/end angle to resize radius from that angle.
• Hold Alt/Opt while dragging the radius to rotate the entire arc.
• Click the origin to toggle rendering styles (see below.)

Supports 3 rendering styles, toggled by clicking the origin control point:

• Arc line - Default style which renders only a single line arc.
• Circle segment - Renders a pie wedge shape.
• Donut segment - Renders a donut wedge shape, adding an additional parameter for the inner radius:
  • Click the inner radius control point to enter a value expressed as pixel (50px) or percent (50%) -- pixel value is absolute, percent value is relative to the outer radius.
  • Hold Ctrl/Cmd while dragging the outer radius control point to maintain the donut width.
