Dynamic blocks were introduced in AutoCAD 2006.
Dynamic grading leaderEdit
This dynamic grading leader block is designed to transform into various required presentation shapes while still keeping its insertion point at the end of the leader, as shown in the figure.
This block uses the following Dynamic block authoring elements:
- Visibility parameter. You can choose between Left attachment and Right attachment for the leader.
- Stretch actions related to Point parameters. When you move one of the attachment points, the block leader stretches.
- Stretch actions related to Linear parameters. You can move one of the arrows to lengthen the line to match the text length.
