Detaches
the selected faces from the associated mesh. The extracted faces become
a separate shell within the existing mesh. If you select the mesh
in object mode both the mesh and any extracted faces get selected.
Mesh > Extract > 
- Separate extracted faces
-
Turn it on to separate
faces automatically after they are extracted. The extracted faces
will be separated into their own separate object. Any pre-existing
shells in the mesh will not be affected. This is the default setting.
If this option is turned
off, you’re in component selection mode with all the extracted faces selected.
- Offset
-
Enter a value to offset the edges of the extruded, extracted,
or duplicated faces.
This option can be used
to produce a bevel effect for extrusions, cut-outs around faces
using Extract, and to uniformly scale
duplicated faces.
polyChipOff node
Additional modifications
can be made to an extracted face(s) by editing the following attributes
on the polyChipOff node using the Attribute
Editor or Channel Box.
Transform Attributes
- Translate
-
This value moves the
extruded or duplicated faces along the X, Y, or Z-axis.
- Rotate
-
This value sets the angle
by which you want to rotate the extruded or duplicated faces around the
X, Y, or Z-axis of the pivot.
- Scale
-
Enter a value to scale
the extrusion or duplicated faces along the X, Y, or Z-axis of the
pivot.
- Pivot
-
This value defines the
point around which the Translate, Rotate and Scale operations are centered.
Poly Chip Off History
- Offset
-
This value specifies
a universal offset for local values.
- Local Translate
-
This value moves the
extrusion or duplicated face locally along the X, Y, or Z-axis.
Positive or negative values indicate how far the extruded or duplicated
faces are moved locally.
- Local Rotate
-
This value sets the angle
at which you want to rotate the extruded or duplicated faces locally around
the X, Y, or Z-axis of the center of the selection.
- Local Scale
-
This value scales the
extrusion or duplicated faces locally along the X, Y, or Z-axis
of the center of the selection.
- Local Direction
-
Enter a value to set
the location of the X, Y, or Z-point in the local axis. Notice how
the manipulator handles change accordingly when you change the Y
direction value to 4.0.
- Random
-
Enter
a value to duplicate faces in random directions, with a value of
0 to 1. Lower values are closer to the specified direction. Higher values
are more randomized.
In the following example,
faces were extruded with random values of 0, 0.5, and 1.
- Duplicate
-
Turn this attribute on
to duplicate the faces instead of extracting them.
- Keep faces together
-
When this attribute is
on, Maya extracts each face separately. When this option is off,
Maya extracts the faces as a whole.
- World space
-
Turn on the World
Space Coords to use the world coordinate system when
you change values randomly.
