To mirror (reflect) geometry objects in a plane (3D), a line (2D), or a point (1D), in the Geometry toolbar, from the Transforms () menu, select Mirror (). You can also right-click the Geometry node to add this node from the Transforms submenu. Then enter the properties of the mirror operation using the following sections:

Select the geometry objects that you want to reflect in the Graphics window. The objects appear in the Input objects list. If the geometry sequence includes user-defined selections above the Mirror node, choose Manual to select geometry objects, or choose one of the selection nodes from the list next to Input objects.

Click the Active button to toggle between turning ON and OFF the Input objects selections.

Select the Keep input objects check box to use the selected geometry objects for further geometry operations.

This section is only available in 2D geometries. From the Specify list, choose Point and normal (the default) to specify a point and a normal vector in the sections below, or choose Edge to use a straight edge as the line of reflection. Add the edge to the Straight edge list. Note that you cannot select auxiliary sketch edges (for example, the radial segments of a Circular Arc) in the Edge selection. When you have selected Edge, the Point on Line of Reflection and Normal Vector to Line of Reflection sections are not available.

The coordinate system in which the plane coordinates and normal vector above are interpreted (in 3D geometries only). From the Work plane list, select xy-plane (the default, for a standard global Cartesian coordinate system) or select any work plane defined above this node in the geometry sequence. If you choose a work plane, the work plane and its coordinate system appears in the Graphics window, using an extra coordinate triad with the directions xw, yw, and zw (which are then used to specify the mirror operation).

Select the Resulting objects selection check box to create predefined selections (for all levels — objects, domains, boundaries, edges, and points — that are applicable) in subsequent nodes in the geometry sequence. To also make all or one of the types of resulting entities (domains, boundaries, edges, and points) that the resulting objects consist of available as selections in all applicable selection lists (in physics and materials settings, for example), choose an option from the Show in physics (Show in instances if in a geometry part; Show in 3D in a plane geometry under a work plane in a 3D component) list: All levels, Domain selection, Boundary selection, Edge selection, or Point selection. The default is Domain selection, which is suitable for use with materials and physics defined in domains. For use with a boundary condition, for example, choose Boundary selection. These selections do not appear as separate selection nodes in the model tree. Select Off to not make any selection available outside of the geometry sequence. From the Color list, choose a color for highlighting the resulting objects selection. See Selection Colors.

If you want to make the resulting entities contribute to a cumulative selection, select a cumulative selection from the Contribute to list (the default, None, gives no contribution), or click the New button to create a new cumulative selection (see Cumulative Selections).

If you have Named Selections that include entities on the input objects, select the Propagate selections to resulting objects (selected by default) check box to update the selections to corresponding entities on the output objects, when possible. Clear the check box to not propagate the selection to the resulting objects. This can be useful in combination with selecting the Keep input objects check box so that the selections refer only to the input objects.

From the Construction geometry list choose On to make the resulting objects available only in the feature’s geometry sequence. The default option Inherit means that the resulting objects become construction geometry if all input objects are construction geometry. Choose Off to never output construction geometry objects. For more information, see Construction Geometry.
