Changing link defaults in your current diagram
Changing the defaults for links allows you to easily create multiple links that have the same attributes. For instance, you may want to choose a common look for all links used in a diagram, or change to a new style for each different class of links.
1.Select a link.
2.Change the link attributes to reflect your preferences using the tools on the Formatting toolbar or menus. For example, this may include line colour, arrowhead, arrow direction, text colour, text size or line thickness.
3.On the Formatting toolbar, click the Defaults button , then choose Set Default.
New links you add to your diagram will use the new defaults.
To apply defaults to existing links in the current diagram, see Applying defaults in your current diagram.
