How to Use Line Command in AutoCAD 2018?

Understanding the Line Command in AutoCAD 2025

The Line command is one of the fundamental tools within AutoCAD, enabling users to create straight line segments with precision. Mastering this command is essential for effective drafting and design. Here’s a comprehensive guide on how to effectively navigate and utilize the Line command in AutoCAD 2025.

Starting the Line Command

  1. Launch AutoCAD: Begin by opening AutoCAD software on your computer.

  2. Accessing the Command:

    • You can initiate the Line command by selecting the Line icon located on the Home tab within the Draw panel.
    • Alternatively, you may simply type L or LINE into the command line and press Enter.

Drawing a Line Segment

  1. Define Start Point:

    • Click on your drawing area to specify the initial point of the line. This can be precisely placed by navigating your cursor to the desired location.
  2. Determine End Point:

    • Move your cursor to where you want the line to end and click again to set your endpoint.
  3. Creating Additional Lines:

    • To add more lines sequentially, continue clicking at new endpoints. Each click will create a new line segment connected to the previous one.
  4. Finalizing the Command:

    • Once you have finished drawing the desired lines, you can exit the command by pressing Enter or Esc. If you wish to close a series of line segments, enter C instead.

Understanding Line Segments

Each line segment you create acts as a distinct line object that can be manipulated independently. Should you need to start a new line from the endpoint of your last line, simply press Enter at the prompt without specifying a new start point. This continuation simplifies the process of connecting multiple segments.

Utilizing the Command Line

The command line serves as an interactive interface that communicates essential prompts and options as you use various commands. When engaging with the Line tool, the command line will guide you to specify the starting and ending points clearly. Should you need to view or manage the command line, you can toggle it on or off using the shortcut CTRL + 9.

Finding Commands in AutoCAD 2025

To ensure full access to all features:

  1. Display the Command Line: Click the View tab, find the Palettes panel, and select Command Line.

  2. Toggle the Command Line: Use CTRL + 9 to show or hide the command line as required.

  3. Access All Commands: Enter COMMANDLINE or COMMANDLINEHIDE into the command prompt to display or conceal this useful feature.
