Understanding the Break Line Symbol in AutoCAD
The break line symbol is a crucial graphical element in technical drawings, indicating where the drawing has been interrupted. This symbolic representation is essential for simplifying complex objects or conveying that a portion has been visually omitted.
Steps to Create a Break Line Symbol in AutoCAD
Step 1: Launch a New Drawing
Start AutoCAD and open a new drawing by selecting the “New” option from the File menu. Ensure your workspace is set up for drafting.
Step 2: Set the Current Layer
To avoid confusion in your drawing, activate the Defpoints layer. This layer is specifically designed for non-plotting objects, ensuring that the break line does not appear in the final printout. You can do this by:
- Clicking on the “Layer” dropdown in the Home tab.
- Choosing the “Defpoints” layer.
Step 3: Drawing the Break Line Symbol
Utilize the Line or Polyline tool to create the break line symbol. The process is as follows:
- Go to the Home tab and find the Draw panel.
- Select either the Line or Polyline tool from the menu.
- Click to set the start point of your break line, and then create your desired break line shape.
Step 4: Create Connection Points
You need to indicate where the break line connects back to the object. For this:
- Type the command POINT into the command line and hit Enter.
- For each connection point that exits the breakline symbol, click on the desired locations where the line will join.
Step 5: Adjusting the Appearance
It may be necessary to modify the appearance of your break line symbol to match the standards of your project. Consider adjusting:
- Linetype to a dashed style.
- Thickness to make the symbol more visible.
Step 6: Finalize the Drawing
Once you are satisfied with the symbol’s appearance and alignment:
- Save your drawing to preserve the newly created break line symbol.
- Review the overall layout to ensure clarity.
