How Do I Create a Breakline Symbol in AutoCAD?

by

Creating a breakline symbol in AutoCAD is a useful technique that allows you to indicate where a break occurs in an object or drawing. This symbol is commonly used in architectural and engineering drawings to show that a portion of an object is not shown or has been intentionally omitted. In this tutorial, we will explore different methods to create breakline symbols in AutoCAD.

Method 1: Using the Breakline Command

If you want to create a simple breakline symbol, you can use the built-in Breakline command in AutoCAD. Here are the steps:

  1. Step 1: Open your AutoCAD drawing and navigate to the location where you want to insert the breakline symbol.
  2. Step 2: Type “BREAKLINE” on the command line and press Enter. Alternatively, you can access this command from the Modify toolbar or ribbon.
  3. Step 3: Specify the first point of the breakline by clicking on the desired location in your drawing.
  4. Step 4: Specify the second point of the breakline by clicking on another location in your drawing.

The Breakline command will automatically create a zigzag line between these two points, indicating a break in the object. You can customize the appearance of this line using various options available within the Breakline command, such as specifying the size and style of the zigzag line.

Method 2: Using Blocks

If you want to create a more complex or customized breakline symbol, you can use blocks in AutoCAD. Here’s how:

  1. Step 1: Open your AutoCAD drawing and navigate to the location where you want to insert the breakline symbol.
  2. Step 2: Type “BLOCK” on the command line and press Enter. Alternatively, you can access this command from the Insert toolbar or ribbon.
  3. Step 3: In the Block Definition dialog box, specify a name for your block and choose a suitable base point for insertion.
  4. Step 4: Draw the desired breakline symbol using AutoCAD’s drawing tools.

    You can use lines, arcs, or other shapes to create a unique symbol that represents a break.

  5. Step 5: Once you have finished drawing your breakline symbol, save the block definition and exit the Block Editor.
  6. Step 6: Type “INSERT” on the command line and press Enter to insert the block into your drawing.
  7. Step 7: Specify the insertion point of the block by clicking on the desired location in your drawing. You can also adjust the scale or rotation of the block if needed.

This method allows you to create custom breakline symbols that can be reused in multiple drawings. You can also modify or update these blocks later if required.

Tips and Tricks

To enhance your breakline symbols further, consider these additional tips:

  • Create a Breakline Layer: Use AutoCAD’s layer functionality to assign a specific layer to your breakline symbols. This way, you can easily control their visibility or apply different properties like linetype, color, or line weight.
  • Annotate Breakline Symbols: If you want to add text or annotations to your breakline symbols, use the Text command in AutoCAD.

    You can position the text alongside or below the breakline symbol to provide additional information.

  • Save and Share Block Libraries: If you frequently use custom breakline symbols, consider creating a block library that contains all your commonly used symbols. This way, you can easily access and share these blocks with other team members or collaborators.

With these methods and tips, you can now confidently create breakline symbols in AutoCAD. Whether you prefer the simplicity of the Breakline command or the flexibility of using blocks, AutoCAD offers multiple options to meet your needs. Experiment with different styles and techniques to create breakline symbols that are both informative and visually engaging.
