2. Objectives Use AutoCAD’s Block Editor
List the parameters and actions that can be used to create a dynamic block.
Insert parameters into blocks
Assign actions to parameters
Insert and use dynamic blocks
Use parameter sets
Modify parameters and actions
Dynamic Symbols

3. Dynamic Blocks Symbol libraries
Can contain hundreds or 1000’s of blocks.
The more blocks you have, the more time required to manage them.
Many blocks resemble several other blocks with only slight variances.
Solution: create a single dynamic block that can be adjusted according to each unique bolt length.

5. Dynamic Blocks Dynamic block A normal block
Has assignable parameters and actions to objects within the block
You can modify a single block and not affect other instances of the same block.
Dynamic Symbols

6. Dynamic Blocks To create a dynamic block
A parameter is inserted into the block.
An action is assigned to the parameter.

7. Dynamic Blocks A parameter An Action
Contains custom properties for objects within the block.
Positions,
Distances
Angles of the block’s geometry.
An Action
Controls how a block’s geometry can be modified in the drawing into the block.
An action is assigned to the parameter.
