How Do I Create a Cutting Line in AutoCAD?

by

Creating a cutting line in AutoCAD is an essential skill for anyone working with technical drawings or architectural plans. A cutting line, also known as a section line, helps to indicate which part of the drawing will be cut through to reveal the internal details. In this tutorial, we will explore different methods to create a cutting line in AutoCAD.

Method 1: Using the Line Tool

To create a cutting line using the Line tool in AutoCAD, follow these steps:

  1. Step 1: Open AutoCAD and navigate to the desired drawing.
  2. Step 2: Select the Line tool from the toolbar or type ‘Line’ in the command bar and press Enter.
  3. Step 3: Specify the starting point of the cutting line by clicking on any point in the drawing area.
  4. Step 4: Specify the ending point of the cutting line by clicking on another point in the drawing area.

You have now successfully created a cutting line using the Line tool in AutoCAD.

Method 2: Using the Polyline Tool

If you prefer to create a more complex cutting line with multiple segments or curves, you can use AutoCAD’s Polyline tool. Here’s how:

  1. Step 1: Open AutoCAD and navigate to your drawing.
  2. Step 2: Select the Polyline tool from the toolbar or type ‘Polyline’ in the command bar and press Enter.
  3. Step 4: Continue specifying additional points to create the desired shape of your cutting line. You can press Enter after each point or use the Close option to automatically close the polyline.

Congratulations! You have now created a cutting line using the Polyline tool in AutoCAD.

Method 3: Using Existing Objects

If you want to create a cutting line by referencing existing objects in your drawing, AutoCAD provides several useful tools. Here’s how you can do it:

  1. Step 1: Open AutoCAD and navigate to your drawing.
  2. Step 2: Select the desired object that you want to use as a reference for your cutting line. It could be a line, polyline, or any other object.
  3. Step 3: Right-click and select Create Section Object. This will create a new section object based on your selected reference object.

You have successfully created a cutting line using existing objects in AutoCAD.

Tips for Creating Accurate Cutting Lines:

  • TIP 1: To create horizontal or vertical cutting lines, make sure to enable Ortho mode by pressing F8 or clicking on the Ortho icon in the status bar.
  • TIP 2: Use layers to organize your cutting lines and make them easily manageable. Assign different colors or linetypes to highlight specific sections of your drawing.

Remember, creating cutting lines accurately is crucial for conveying the intended information in technical drawings. Practice using different tools and techniques in AutoCAD to master this skill.

Now that you have learned different methods to create cutting lines in AutoCAD, you can confidently apply this knowledge to enhance your technical drawings and communicate your design ideas effectively.
