Procedure
To create a mirror curve:
1.
In a NURBS object that contains at least
one curve, turn on Mirror.
2. On the Mirror Curve rollout, choose the axis or
plane you want to use.
3. Click the curve you want to mirror , and drag to
set the initial distance.
Amirrorcurveiscreated.Agizmo(yellowby
default) indicates the direction of mirroring.
Transforming the mirror curve’s gizmo changes
the orientation of the mirror, letting you mirror

coordinate axis.
4. Adjust the mirror parameters.

In v iewports a gizmo (yellow by default) indicates
the mirror ax is.
Mirror Curve rollout (creation time)
Mirror Axis group
The Mirror Axis buttons control the direction in
which the original curve is mirrored.
You can’t transform the mir ror curve directly (that
would simply transform the mirror cur ve
and its
parent curve at the same time). You transform it
by transforming its gizmo. By using transforms
you can mirror about an arbitrary axis, rather
than using one of the Mirror Axis presets. When
you transform a mirror curve, you are actually
tra nsforming the mirror plane, so Rotate has the
effect of rotating the plane about which the curve
is mir rored. (This is like rotating the mirror gizmo
in the Mirror modifier.)
Offset—Controls the mirror’s distance from the
original curve.
This parameter is animatable.
