Mirror Components: Status dialog box

The top of the dialog box groups Components, Mirror Plane, and Create Mirror Pattern.

Components

Selects components to mirror. Select a component in the graphics window or browser. All child components are automatically included.

Mirror Plane

Select a work plane or planar face as the mirror plane.

YZ Plane

Specifies the Origin YZ Plane as the mirror plane.

XZ Plane

Specifies the Origin XZ Plane as the mirror plane.

XY Plane

Specifies the Origin XY Plane as the mirror plane.

Note: If the Origin planes have been renamed, the custom names display for the dialog selections.

Create Mirror Pattern

When selected, creates an associative mirror pattern. Mirrored components are placed in a Mirror browser node, and geometry and position stay associated with the source components.

When cleared, creates a legacy mirror with no associativity between the source and target documents.

Mirror, Reuse, and Exclude

Set the mirror status for selected components. The dialog box groups controls under Mirror, Reuse, and Exclude. Use the controls under the active status column to apply that status to the selection, or click a status icon for an individual component in the browser tree. Additional controls are shown or hidden based on the active status.

Note: When the mirror status of a parent component changes, all children automatically inherit the parent status.

Mirror Creates a mirrored component and saves it in a new file.

Reuse Adds a component instance in the current or a new assembly file. Components marked bold are not suitable for reusing. A component must be symmetric according to its current symmetric plane to be suitable for reuse. Asymmetric reused components can be positioned incorrectly in the resulting model.

You can apply the enhanced object orientation for reused components. Right-click the component and select the Symmetric Plane. The orientation of the component is changed with respect to the plane.

Exclude Excludes the component from the mirror operation.

Mixed Indicates that child components are either reused or excluded.
