Add Actions and Parameters to Block Definitions
In a block definition, actions and parameters provide rules for the behavior
or a block once it is inserted into the drawing.
Depending on the specified block geometry, or parameter, you can associate
an action to that parameter. The parameter is represented as a grip in the
drawing. When you edit the grip, the associated action determines what will
change in the block reference.
Just as with constraint parameters, action parameters can have editable
properties that are changed using the Properties Manager.
Quick Start to Creating Dynamic Blocks
Know how the block should change or move, and
what parts will depend on the others.
Example: The block will be resizable, and after it
is resized, additional geometry is displayed.
-----Plan the block content.
Draw the block geometry in the drawing area or
the Block Editor.
NOTE If you will use visibility states to change
how geometry is displayed, you may not want to
include all the geometry at this point. For more
information, see Control the Visibility of Objects
in a Block on page 953.
-----Draw the geometry.
Add either individual parameters or parameter
sets to define geometry that will be affected by

an action or manipulation. Keep in mind the
objects that will be dependent on one another.
