Symmetry
The Symmetry modifier is especially useful when
modeling characters or building ships or aircraft.
This modifier is un ique in that it allows you to
perform three common modeling tasks:
• Mirror a mesh about the X, Y, or Z plane.
• Slice a mesh, removing parts if necessar y.
• Automatically weld vertices along a common
seam.
Examples of using Symmetry w ith different mirror axes or by
moving the mirror gizmo
You can apply the Symmetry modifier to any
geometry, and you can animate the mirror or
slicing effect by animating the modifier’s gizmo.
When the Symmetry modifier is applied to a mesh,
any edits you make to the original half of the mesh
below the Symmetry modifier in the stack also occur
interactively to the other half. For an example, see
the second procedure, below .
Note: The Symmetry modifier converts p atch and
NURBS objects to mesh format in the modifier
stack; editable poly and editable mesh objects
remain in their original format.
Procedure
Example: To apply the Symmetry modifier to an
obj ect:
1.
Create a teapot in the Perspec tive viewport.
