| Step 1. | Choose Home tab→Pattern group→Mirror→Mirror Copy Feature. 
 | |
| Step 2. | Select one or more part features to copy, then click the Accept (check mark) button on the command bar. Note: If you want to copy a treatment feature, such as a round, chamfer, or draft, you must also select its parent feature for copying. For example, to copy a draft feature, you must select the feature with the drafted sides. 
 However, you can copy a feature without copying its treatment features.

| Step 3. | Define the plane about which you want to mirror the features. | |
| Step 4. | Finish the feature. | 
Tip:
You can select the features you want to copy before clicking the Mirror Copy Feature button. The command automatically advances to the Plane step.
