FIG. 3.2
Mirroring Geometry creates a second side of polygons and enables symmetry so changes are rel ected
on both sides.
FIG. 3.3
Instance Mirroring shows a seam and a mirrored ghost half of the object that can be disabled and
re-enabled.

Now we are ready to

Mirror Geometry
( Figure 3 2b ).
This should create a second mirrored side to the model (Figure 3.2c), since it's
making the geometry on one side of the blue grid line match the geometry
on the other side. This command will also turn on symmetry, so that any
changes made to one side of your model will also happen on the other, as in
Figure 3.2d .

can control
the direction in which the mirroring happens and whether the two mirrored
sides will merge vertices along the seam within a certain distance of the
axis. Often it is helpful to open this window when performing a mirroring
operation. The symmetry of the two sides can be disabled at any time using

The other important type of mirroring is
Instance Mirroring
( Figure 3.3 ). As
opposed to geometry mirroring,
Instance Mirroring
does not actually create
new polygons, but simply creates a mirrored “instance” of your model. With
an instance mirror, only one side of your model will actually exist as editable
