BACTION (Quick Reference)-Autodesk AutoCAD 2008 Command Reference-kxcad

You can only use the BACTION command in the Block Editor. Actions define how the geometry of a dynamic block reference will move or change when the custom properties of a block reference are manipulated in a drawing. You associate actions with parameters.

Select parameter: Select a parameter in the block definition with which to associate the action

Select action type [Array/Move/Scale/Stretch/Polar Stretch]: Select an action type to associate with the parameter (the available actions types depend on the type of parameter selected)

If you select a rotation parameter, a rotate action is automatically added to the dynamic block definition and associated with the selected parameter.

If you select a flip parameter, a flip action is automatically added to the dynamic block definition and associated with the selected parameter.

If you select a lookup parameter, a lookup action is automatically added to the dynamic block definition and associated with the selected parameter.
