Creating dynamic blocks is an extension of creating static block definitions. You can make the process easier and more likely to succeed with sufficient planning, incremental changes, and testing in the Block Editor.

General Workflow
Plan the block content | Plan how the block should change or move, and what objects will depend on the other objects. For example, you might decide that the block should be able to be resized in a specific direction, after which additional geometry is displayed. |
Create the geometry | Create the geometric objects for the block in the Block Editor. If you plan to use visibility states to control when geometry is displayed, you might not want to include all the geometry at first. |
Add geometric and dimensional constraints (not in AutoCAD LT) | It usually makes sense to add constraints to the geometry first, before adding parameters and actions. Specify the dimensional constraints from the Constraints tab on the Block Authoring palette. |
Add parameters | Add parameters to specify which objects will be affected by an action. the directions and values that can affect how geometry in the block might be manipulated. |
Add actions | Add actions to define what will happen to the geometry when it is manipulated. |
Define parameter properties | Add properties that determine how the block is displayed in the drawing area. Parameter properties affect grips, labels, and preset values for the block geometry. Consider how geometric objects might be affected if actions are chained together. |
Test the block | On Block Editor contextual tab, Open/Save panel, click Test Block to test the block before you save it. A good practice is to test the block after each change to catch any errors early. |
Save the block | On the Block Editor contextual tab, Open/Save panel, click Save Block or click in the Close panel, Close Block Editor and then click Save the Changes. |
Note: It is possible to create constraints that conflict with parameters and actions.

Fattening games deviantart. The following is an example of adding constraints followed by adding actions and parameters.
Add Constraints (not available in AutoCAD LT)
In a block definition, constraints do the following: Audacity music software free download. Adobe acrobat 8 professional 8.0.0 serial key crack and keygen.
- Associate objects with one another
- Restrict geometric relationships or dimensions
- May contain expressions representing formulas and equations
The following illustration shows a block reference with two types of dimensional constraints used in a dynamic block. Alt j an awesome wave zip download.
- The gray dimensional constraint, d1, was specified using the Parametric tab on the ribbon. It's applied to the block geometry, but it cannot be accessed or modified once the dynamic block is inserted into a drawing.
- The blue dimensional constraint, d2, has 1 grip associated with it. This constraint was specified from the Constraints tab of the Block Authoring palette as a Horizontal constraint parameter. Constraint parameters combine a dimensional constraint with a parameter. This is how you can display a custom grip associated with a dimensional constraint.
The number of accessible grips on a constraint parameter is specified in the Properties palette from within the Block Editor.
After the block is inserted into the drawing, the constraints are maintained, but the value associated with d1 can be changed with the Properties palette in a similar manner to how you would change object properties.
Add Actions and Parameters
In a block definition, actions and parameters provide rules for the behavior of a block once it is inserted into the drawing.

In general, you first create a parameter and then you associate an action to that parameter. A parameter is represented as a parameter point with one or more custom grips that display when the block is inserted into the drawing and selected.
Note: When a yellow box with an exclamation point appears in the Block Editor, is usually signifies that a parameter does not have an associated action yet.
When you insert the dynamic block in a drawing and manipulate one of its custom grips, the associated action determines what will change in the dynamic block. Just as with parameters, actions can be changed using the Properties palette from within the Block Editor.
