(Dynamic Blocks)
Instead of being a fixed part of a drawing, a dynamic block reference can be changed or
manipulated as you work in a drawing.
Overview of Dynamic Blocks
Dynamic block definitions allow you to edit a block reference outside of the
Block Editor. They contain rules, or parameters, for how to change the
appearance of the block reference when it is inserted in the drawing.
A dynamic block reference inserts one block that can be edited in several different
ways. For example, instead of creating multiple interior door blocks of different
sizes, you can create one resizable door block.
You author dynamic blocks with either constraint parameters or action
parameters.
NOTE Using both constraint parameters and action parameters in the same block
definition is not recommended.
Constrain Block Definitions
In a block definition, constraint parameters
Associate objects with one another
Restrict geometry or demensions
Once the block is inserted into the drawing, the constraint parameters can be
edited as properties by using the Properties Manager.
