Mirror And Weld
From ZBrush Info
This function allows you to mirror geometry across an axis or axes. Select the axis by clicking on the little x, y or z on the right side of the button. Points that intersect will be welded and overlapping geometry will be removed.
Two things should be borne in mind:
- Objects cannot have subdivision levels. As the resulting mesh may contain triangles, it may not be possible to reconstruct subdivision levels.
- The position relative to the axis affects how the overlapping geometry is removed. The floor grid axes (see the Draw palette) give a good indication of how this works. For example, when mirroring along the X axis, all geometry on the left (where the red X axis is shown) will be mirrored whereas any geometry on the right will be removed. If all geometry is on the right then everything will disappear!
