How to Burst in AutoCAD LT?

Understanding the Burst Command in AutoCAD LT

When working with AutoCAD, one may find the need to manipulate and edit blocks effectively. The Burst command is a key tool for this, allowing users to separate attributes without altering the original text. This guide details how to utilize the Burst command in AutoCAD LT.

Steps to Access the Burst Command

  1. Open the Block Editor:
    Begin by locating the block you wish to burst. Open it by right-clicking on the block and selecting "Edit Block In Place" or accessing it through the Block Editor.

  2. Prepare for Modification:
    Ensure that no objects within the block are currently selected. This is crucial because selections can interfere with the options you need to adjust.

  3. Open the Properties Palette:
    Press Ctrl + 1 to open the Properties palette. This is where you can modify the settings of the block.

  4. Locate the Allow Exploding Option:
    In the Properties palette under the Block section, find the option labeled "Allow Exploding." This setting governs whether the block can be exploded or burst.

  5. Set to Yes:
    Change this option to "Yes." This will enable the block to be burst and allow you to maintain the visual fidelity of the text within the attributes.

  6. Save Changes:
    After adjusting the properties, save your changes by clicking the Save Block Definition button in the Block Editor toolbar.

  7. Using the Burst Command:
    Exit the Block Editor and return to the main drawing area. Type BURST into the command line and hit Enter. You may also access it through the Modify dropdown menu. Select the blocks you previously modified; they will now separate the attribute text from the block properly.

When to Use the Burst Command

The Burst command is especially useful when dealing with attribute blocks. When you burst these blocks, it retains the text as-is instead of converting it to tag values, which can occur if you use the standard Explode command. This is beneficial for maintaining clarity in your drawings, especially when editing complex elements.

Differences Between Burst and Explode

Understanding how Burst differs from the Explode command is essential:

  • Burst Command: Retains text integrity within attribute blocks, separating the attributes while keeping the text unchanged.
  • Explode Command: Destroys the attributes’ text quality by replacing it with tag values, leading to loss of information.

Frequently Asked Questions (FAQ)

1. Can I burst any block in AutoCAD LT?
No, you can only burst blocks where the "Allow Exploding" option is enabled during block creation. If it is not set, you need to modify this setting first.

2. What happens if I explode an attribute block instead of bursting it?
If you use the Explode command on an attribute block, the text associated with the attributes will change to the predefined tag values instead of remaining intact.

3. Is the Burst command available in all versions of AutoCAD?
The Burst command is available in AutoCAD 2025 and later versions, allowing for better management of attribute blocks, unlike earlier versions which may not support this feature fully.
