Actions define how the geometry of a dynamic block reference will move or change when the custom properties of the block reference are manipulated in a drawing.
In a dynamic block reference, a move action behaves similar to the MOVE command.
In a dynamic block reference, a scale action behaves similar to the SCALE command.
In a dynamic block reference, a stretch action causes objects to move and stretch a specified distance in a specified location.
In a dynamic block reference, a polar stretch action rotates, moves, and stretches objects a specified angle and distance.
In a dynamic block reference, a rotate action behaves similar to the ROTATE command.
A flip action allows you to flip a dynamic block reference about a specified axis called a reflection line.
In a dynamic block reference, an array action causes its associated objects to copy and array in a rectangular pattern when the associated parameter is edited through a grip or the Properties palette.
When you add a lookup action to a dynamic block definition and associate it with a lookup parameter, it creates a lookup table. You can use a lookup table to assign custom properties and values to a dynamic block.
Some actions have distance multiplier and angle offset override properties. These properties allow you to specify a factor by which a parameter value is increased or decreased when the parameter is edited in a dynamic block reference.
