Set the Shape Outline on a PowerPoint 2007 Slide
PowerPoint’s Shape Outline control lets you change the style of line objects or the border for solid shape objects on your PowerPoint slides. The Shape Outline control is located in the Shape Styles group of the Drawing Tools tab. You can change the following settings for the outline:
Color: Sets the color used for the outline.
Weight: Sets the thickness of the line.
Dashes: The dashing pattern used for the lines that outline the object. The default uses a solid line, but different patterns are available to create dashed lines.
Arrows: Lines can have an arrowhead at either or both ends. Arrowheads are used mostly on line and arc objects.
For maximum control over the outline style, select the More command from the menu that appears when you click the Fill, Outline, or Effects buttons. This brings up the Format Shape dialog box. From this dialog box, you can control all aspects of a line’s style: its color, width, dash pattern, and end style (various arrowheads can be applied).
