Leaders and multileaders are used to add call outs to your drawings. You can create annotative leaders through an annotative dimension style and multileaders through an annotative multileader style.
Multileaders: leader objects that create annotations with multiple leader lines.
When you create a leader, you create two separate objects: the leader and the text, block, or tolerance associated with the leader. When you create a multileader, you create a single object.
If the multileader style is annotative, the associated text or tolerance will be annotative as well, regardless of the annotative setting of the text style or tolerance.
Note: It is recommended that you create non-annotative entities when creating a mleader content block.
Blocks used in leaders and multileaders must be non-annotative. You can change the Annotative property of leaders and multileaders in the Properties palette.
