The General Layout options are only available if you have the Central Topic selected. These options apply to the entire map.
Do one of the following:
Right-click on the Central Topic and select Format Topic.
Select the Central Topic and click Format - Topic.
On the General Layout tab, choose the desired attributes for the map.
Organic appearance makes the main topic connecting lines look more like hand-drawn lines.
Display shadow adds a shadow to the topic connecting lines and topic shapes.
Main Topic Line Width makes main topic connecting lines thicker or thinner.
Minimum Main Topics Height controls the vertical spacing between the main topics.
Use the Style button if you wish to:
Save these attributes as the default style for topics at this level on the current map. The settings become part of the current map's style. All existing topics at this level will use these attributes (unless they have been individually formatted), as will any new topics you create. You will see these new attributes reflected if you use the Modify Style command.
Reset all of the topic's attributes to the defaults of the current style.
