When you place symbols or balloons in the drawing, multiple leader segments are created until you right-click and click Continue. Select the Single Segment Leader option to create drawing annotations with a single leader segment. The Single-Segment Leader option is available for balloons, leader text, surface texture symbols, welding symbols, feature control frames, datum targets, and sketch symbols.
The setting is saved in the computer registry and is retained until you change it. You set the option separately for each type of symbols.
In this example, the Surface Texture Symbols are set to be created with single-segment leaders.
Horizontally aligned annotations are aligned along the Y axis, and the X-axis position does not change. Vertically aligned annotations are aligned along the X axis, and the Y-axis position does not change. Annotations aligned to an edge are moved in direction perpendicular to the edge.
To avoid overlapping and to keep a specific offset distance between annotations, hold the CTRL key when placing the aligned annotations. To set the distance between annotations, in the current balloon style, edit the Default Offset value. If you set the Default Offset value to zero, there is no offset, and the annotations are aligned tangent to one another.
Select a symbol, and then on the Annotate tab, Format panel, click the arrow on the Style list and select a style to apply to the symbol. To change appearance of all symbols using a style, edit the style settings in Style and Standard Editor.
