Understanding Break Lines in AutoCAD 2025

Break lines are essential in technical drawings, helping to indicate sections of an object that have been removed for clarity. Utilizing break lines effectively allows for clearer communication in design documentation.

Steps to Draw a Break Line in AutoCAD 2025

Step 1: Initiate the Break-Line Command

Start by typing BREAKLINE into the command prompt and press the ENTER key. This command activates the break line function.

Step 2: Specify Starting Point

Click on the drawing area to specify the starting point for your break line. This point marks the beginning of the gap in the line.

Step 3: Indicate Ending Point

Next, click to specify the ending point of the break line. This marks where the break line will conclude.

Step 4: Choose Location for Break Symbol

After defining the two ends of the break line, you will be prompted to specify the location for the break line symbol. Click in the desired position where you want the break symbol to appear.

Step 5: Verify and Adjust

Once you have placed the break line, review your drawing to ensure its accuracy and make any necessary adjustments. You may need to zoom in and out to ensure the line appears as intended.

Drawing Break Lines in AutoCAD LT 2025

The procedure for drawing break lines in AutoCAD LT is slightly different. Access the break line tool via the Drafting tab. Navigate to the Draw panel and select the Break-Line Symbol option. Just like in AutoCAD, specify the points and the location of the symbol to complete your drawing.

Creating a Broken Section in AutoCAD

Step 1: Use the Polyline Tool

To indicate a broken section, first access the Home tab, then click the Draw panel and select the Polyline option. Use this tool to create a closed polyline that outlines the desired view to show where the section cut occurs.

Step 2: Generate a New View

Next, go to the Drawing tab and select New View. A dialog box will appear prompting you to define the new drawing view.

Step 3: Select Parent View

You will be asked to choose the parent view. Click on the view containing the cut line you previously created. This action establishes the relationship between the cut line and the new section view.
