Quick Reference

To add a rotation parameter to a dynamic block definition

In the Block Editor, in the Block Authoring Palettes window, Parameters tab, click the Rotation Parameter tool.
(Optional) Follow the command prompts to specify the following for the parameter:
- Name
- Label
- Description
- Value set
- Chained Actions
- Properties displayed for block reference
NoteYou can also specify and edit these properties in the Properties palette at a later time, after you've added the parameter to the block definition.
Do one of the following to specify a base point for the parameter:
- Use the pointing device.
- Enter the X and Y coordinate values, separated by a comma.
Do one of the following to specify the radius for the parameter:
- Use the pointing device.
- Enter a value.
Specify a base angle for the parameter.
The angle shown in the Properties palette when you select the block reference in a drawing is measured relative to the base angle specified in the block definition.
Do one of the following to specify a default rotation angle for the parameter:
- Use the pointing device.
- Enter an angle value.
Do one of the following to specify a location for the parameter label:
- Use the pointing device.
- Enter the X and Y coordinate values, separated by a comma.
  The yellow alert icon indicates that you should associate an action with the parameter you just added.
