Use the Mirror dialog to mirror selected elements in the active Face window. When working in:
- CAD mode, you can mirror selected geometry.
- CAM mode, you can mirror selected holes and/or profiles.
To display the Mirror dialog, select the elements that you want to mirror in the active Face window, then select Edit > Transform > Mirror.

The following settings are available:
Multiple Copies — Select this option to copy the selected elements. When mirroring elements, only one copy is allowed, as displayed in the No. of Copies field.
Mirror Axis (PM) — Select whether to use the Horizontal axis, Vertical axis or an Inclined axis for mirroring the selected elements.
Angle (A) — Enter the angle for mirroring the selected elements when using an Inclined axis.
Center (P) — Specify the center point for mirroring the selected elements. There are two ways to specify the center:
- Entering coordinate values. If you know the coordinate values of the point, enter these values in the Z and X, or X and Y, fields. The Coordinates values vary depending on the type of Face window you are using – X and Y coordinates are displayed for a Milling Face window and Z and X coordinates are displayed for a Turn Face window.
- Clicking
and selecting the point interactively. PartMaker displays a cross-hair cursor for you to select a center point in the Face window. The Snap Modes toolbar also appears for you to select a snap mode.
Mirror — Click to mirror the selected elements using the settings specified in the dialog.
