Creating a mirrored instance is most useful for symmetrical components.
There are two options for creating a mirrored instance. You can use either the center of mass or bounding box, which determines the rotation axis.
When you specify to create the mirrored component as a copy of the seed component (rather than an opposite-hand version) the software creates four possible orientations for the mirrored instance. For the first orientation of the mirrored instance, the software creates three virtual axes in the same directions as the component’s axes and with the origin at the center of mass or bounding box center. To achieve the other orientations, the software flips the mirrored instance about its center of mass or bounding box center in the x direction, the y direction, or both the x and y directions.
- In all orientations, the centers of the seed component and the mirrored instance are equidistant from the mirror plane.
- For a fully symmetric component (symmetry in all three axes), all four orientations are true mirrors.
- For a partially symmetric component (symmetry in one or two axes), one of the orientations might be a true mirror. The rest are flipped orientations.
- For non-symmetric components, none of the orientations is a true mirror; all are flipped orientations. If you want a true mirror, create an opposite-hand version.
Before starting this procedure, open the Mirror Components PropertyManager and select the mirror plane and the components to mirror. See Selecting the Mirror Plane and Components.
To create a copy and specify its orientation:
- In the PropertyManager, on the Step2: Set Orientation page, under Orient components, select a component to copy.
- Click Reorient
and 
to cycle through the four possible orientations.
- Under Mirror Type, click Center of Mass or Bounding Box.
Locating the mirrored components in the bounding box center is typically more desirable for asymmetric components because the bounding box is unaffected by the components' features.

Do one of the following:
-
If you are creating only copies (no opposite-hand versions), click
.
The PropertyManager closes and new instances of the components are added to the assembly, mirrored about the plane you selected. A MirrorComponent 
feature is added to the FeatureManager design tree.
- If you are creating one or more opposite-hand versions, see Creating Opposite-Hand Versions.
