How To Get Break Line In AutoCAD?

Understanding Break Lines in AutoCAD

Creating break lines in AutoCAD allows you to represent sections of objects or to symbolize where a part of a drawing has been omitted for clarity. Here’s a guide on how to effectively insert and manipulate break lines in your AutoCAD drawings.

Step-by-Step Guide to Creating Break Lines in AutoCAD

Step 1: Accessing the Home Tab

Begin by launching your AutoCAD 2025 application. Ensure you have your drawing open. Navigate to the Home tab located at the top of the interface.

Step 2: Selecting the Polyline Tool

In the Draw panel, locate and click on the Polyline tool. This tool is commonly used to create complex shapes and lines.

Step 3: Drawing the Break Line

Click to set your starting point on the drawing canvas. Continue clicking to define additional points that shape your break line. If you need to create a closed shape, return to the starting point to complete the polyline. Once done, press Enter to finalize the drawing.

Step 4: Modifying Line Type

Next, you may want to adjust the appearance of the break line to distinguish it from other elements. Right-click on the polyline you just created and choose Properties. Here, you can change the line type to dashed or any other style that fits your design needs.

Step 5: Placing the Break Symbol

If necessary, you can insert a break symbol to indicate interruption in structural elements. Access the Insert tab and choose the desired break symbol from your libraries or draw one manually using basic shapes and the Arc tool.

Step 6: Final Adjustments

Reposition the break line and symbols as needed to ensure clarity in your drawing. Use the Move and Rotate commands to align these elements properly.


Advanced Techniques for Break Lines

Defining a Section Line

In addition to break lines, section lines are used to indicate where a view cuts through a material. To create section lines:

  1. Select the Line tool from the Draw panel.
  2. Draw thin straight lines at a 45-degree angle to represent the cut. These lines are typically used in technical drawings to convey complex spatial information clearly.

Frequently Asked Questions
