Screen
In this mode, the object is mirrored in the current projection plane. If you rst click in the area of the
upper or lower window border, you get a horizontal mirror axis. If you rst click in the area of the
right or left window border, you get a vertical mirror axis.
Mirror Plane
This mode is available for the world and the object coordinate system. Select the XY, ZY or XZ plane.
Depending on the selected coordinate system, the mirror plane refers either to the world or object
axis.
Weld Points
This option is important if, for example, you mirror a cube over one of its edges and Duplicate
Points is enabled. After mirroring, some of the points may be in the same positions. If Weld Points
is enabled, these duplicate points are welded after mirroring. The adjacent input box allows you to
enter a distance; any point that has a duplicate point within this distance will be welded into one
single point.
Value
Use this to position the mirror axis numerically. This works only with the object and world coordinate
systems and allows you to freely dene the distance of the mirror axis from the axis origin.
