How Do You Edit a Dynamic Block in AutoCAD?

AutoCAD is a powerful software that allows you to create and edit complex designs and drawings. One of the key features of AutoCAD is dynamic blocks, which are customizable objects that can change shape, size, or configuration based on defined parameters.

In this tutorial, we will learn how to edit a dynamic block in AutoCAD and make changes to its properties.

Step 1: Access the Block Editor

To edit a dynamic block in AutoCAD, you need to access the Block Editor. There are several ways to do this:

  • Method 1: Type “BEDIT” in the command line and press Enter.
  • Method 2: Right-click on the block you want to edit and select “Block Editor” from the context menu.
  • Method 3: Go to the “Home” tab on the ribbon, click on the “Block Editor” button in the “Block” panel.

Step 2: Make Changes to the Block

Once you are in the Block Editor, you can make changes to your dynamic block. Here’s how:

  • Add New Parameters: To add new parameters to your dynamic block, click on the “Parameter” panel in the ribbon. You can add various types of parameters like linear, polar, or alignment parameters depending on your requirements.
  • Create Actions: Actions determine how your dynamic block will behave when its parameters are modified.

    To create actions, go to the “Action” panel in the ribbon. You can define actions like stretching, rotating, or scaling the block based on the parameter values.

  • Modify Block Geometry: To modify the geometry of your dynamic block, use the editing tools available in the “Home” tab or other relevant tabs in the ribbon. You can move, resize, or delete individual objects within the block.

Step 3: Test and Save Your Changes

Once you have made the necessary changes to your dynamic block, it’s important to test them before saving. To test your block, exit the Block Editor by clicking on the “Close Block Editor” button in the ribbon.

Now, try modifying the parameters of your dynamic block and observe how it responds to changes.

If you are satisfied with your edits, save your dynamic block by clicking on the “Save Block” button in the ribbon. Give it a name and choose a suitable location to save it.


Editing a dynamic block in AutoCAD allows you to create highly flexible and customizable designs. By adding parameters, defining actions, and modifying geometry, you can create blocks that adapt to different situations and save time during the design process.

With practice and experimentation, you can master this powerful feature of AutoCAD and enhance your productivity as a designer.
