Using the mirror tool you can create a duplicate of the selected geometry in the active layer. When the mirror tool is active, it creates an axis, across which the geometry is duplicated in a flipped or "mirrored" orientation to the original. With the tool active you can interactively position the mirror plane to change the distance of the mirrored geometry, or change the rotation of the plane to adjust the orientation of the duplicated geometry.
The mirror tool has the following options:
Axis (XYZ option): Sets the axis for the mirror plane.
Angle: This degree value determines rotation of the mirror plane around the Axis. The default value of 180 degrees created a perfect mirror flip. By increasing or decreasing this value, you can skew the mirror plane to create a acute or obture angle between the original and new geometry.
Free Rotation: The default setting of this toggle is off, in which case the major axis of the mirror is set by the Axis setting (see above). When this option is activated, you can pivot the main axis to any arbitrary setting by dragging the topmost handle of the mirror tool.
Center (XYZ values): The center values set the position for the main mirror plane. This value can be set numerically, or by direct manipulation of the mirror tool handle. To adjust the position, you must drag the bottom corner of the handle.
Merge Vertices: When active this option will attempt to merge any vertices overlapping between the original and new geometry.
Range: The Range option depends on Merge Vertices being active. If Merge Vertices is inactive, this option will be ghosted and is thusly unavailable. When this option is activated you can set a Distance value for the merging. Any points within the user determined range will be merged together.
Distance: This funtion depends on the activation of the Range option. The Distance is a simple measurement to determine the threshold for merging points from the new and original geometry.
