How to Use Mirror in AutoCAD?

The Purpose of the Mirror Command in AutoCAD

The Mirror command in AutoCAD is a powerful tool that enables users to create a mirrored or reverse duplicate of selected objects. To utilize this feature, first, select the desired objects within your drawing. Following this selection, AutoCAD will prompt you to identify two points. These points will define a line, serving as the axis of reflection for your mirrored copy. You will then have the option to keep or remove the original objects after the mirroring process.

Accessing the Mirror Command

To activate the Mirror command, you can either access it from the toolbar or type “MIRROR” into the command line and press Enter. This method simplifies the process, allowing you to quickly initiate the command without navigating through menus.

Steps for Mirroring Objects in AutoCAD 2025

  1. Begin by launching your AutoCAD 2025 application and opening the drawing file containing the objects you want to mirror.
  2. Select the objects you wish to mirror. This can include lines, shapes, or any drawn entities.
  3. Once you have made your selection, type “MIRROR” into the command line and hit Enter.
  4. Prompted to select two points, click on the first point to establish the starting point of your mirror line.
  5. Next, click the second point to define the end of your mirror line. This line will determine the axis along which your selected objects will be mirrored.
  6. After defining the mirror line, AutoCAD will ask if you want to delete the original objects. Press “Y” for Yes or “N” for No based on your preference.

Understanding Text Mirroring in AutoCAD

Mirroring text in AutoCAD can be tricky, as text can appear inverted when using the Mirror command. To avoid this, ensure that the MirrText setting is set to zero. This adjustment allows the text to remain readable while the surrounding objects are mirrored. You can adjust this setting by typing “MirrText” into the command line and changing it as needed.

Key Differences Between Copy and Mirror

When comparing the Copy command to the Mirror command, it is essential to understand their distinct functions. Copies create exact replicas of selected objects, essentially “cloning” them. In contrast, mirrored objects become new entities with unique identifiers. While mirrored objects can be affected by some editing tools, like Press Pull, they may not respond to others, such as Extrude.

Frequently Asked Questions

Can I mirror text in AutoCAD without it being flipped?

Yes, by ensuring the MirrText setting is at zero, you can mirror objects without affecting the orientation of the text.

What is the shortcut key for activating the Mirror command?

The Mirror command can be activated through the command line by typing “MIRROR.” Alternatively, you can access it from the relevant menu in AutoCAD 2025.

How many layers should I use in my AutoCAD drawing?

It is advisable to create multiple layers to organize your drawing effectively. While every drawing starts with a default Layer 0, developing additional layers can help maintain clarity and structure in complex designs.
