Mirror
A command that creates a reversed copy of selected objects across a defined mirror line.
- MI
The Mirror command reflects geometry across a user-defined line. It is useful whenever the drawing contains symmetry and repeating forms.
Where It Appears
You launch Mirror with MIRROR or MI. It is common in plans, furniture layouts, mechanical parts, and any drawing where a left-right or top-bottom counterpart is needed.
Why It Matters
Mirror saves time and protects symmetry. Instead of recreating balanced geometry by hand, you can generate it directly from the accurate original.
How This Shows Up in AutoCAD
This term names something the user actively runs. It usually appears in the command line, ribbon, or step-by-step drafting instructions while geometry is being created or modified. Mirror sits in the Commands part of the glossary, which tells you the term is most relevant when that stage of work is active.
Mirror is also commonly referenced as MI. Those alternate names usually show up in shortcuts, office standards, template notes, or informal team conversations, so recognizing them makes the term easier to spot in real work.
What This Usually Tells You
When this term is mentioned, the important context is usually sequence: what you select first, which option you choose next, and how the command is finished. That is why command terms matter so much in training. They describe actions, not just labels, and each action changes the drawing state immediately.
For Mirror, the practical takeaway is that the term usually marks a repeatable drafting decision, not a one-off trick. It signals something a user should recognize, control, or verify on purpose.
Common Mistakes
A common mistake is learning the command name but ignoring the surrounding input rules. Snaps, tracking, selection order, and confirmation steps often determine whether the result is clean or messy.
Mirror is easiest to separate from nearby ideas such as Arc, Circle, Copy, and Extend. Reading those terms together clarifies which part of the workflow belongs to Mirror and which part belongs to adjacent tools or concepts.
