Mirror Surface 1187
Offset S urface rollout (modification time)
Offset—The distance between the parent surface
and the offset surface in 3ds Max units.
If the p arent surface is planar, the appearance of
the offset surface doesn’t change with distance. If
the parent surface is cu rved, increasing the offset
value increasingly exaggerates the curvature of the
offset surface.
Replace B ase S ur face—Lets you replace the parent
surface. Click the button, then click the new
surface on which to base the offset.

A mirror sur face is a mirror image of the origina l
surface.
Surface created as a mirror
Procedure
To create a mirror surface:
1.
In a NURBS object that contains at least
one surface, turn on Mir ror.
2. On the Mirror Surface rollout, choose the axis
or plane you want to use.
3. Click the surface you want to mirror, and drag
to set the initial distance of the mirror surface.
The mir ror sur face is created. A gizmo (yellow
by default) indicates the direction of mirroring.
Transforming the mirror surface’s gizmo
changes the orientation of the mirror, letting
you mirror along an axis that isn’t aligned with
alocalcoordinateaxis.
The Flip Normals control lets you flip the
surface normals at creation time. (After
creation, you can flip normals using controls on
the Surface Common rollout.)
4. Adjust the Offset p arameter.
Interfa ce
While a mirror surface sub-object is selected, the
Mirror Surface rollout appears at the bottom of the
Modify panel. Also, a gizmo (yellow by default)
indicates the mirror axis.
