The point, row, or column is deleted. Deleting a
"single" point actually deletes both the row and
column to which the point belongs.
To add a point to a curve:
1.
IntheRefinegroupbox,turnonCurve.
2. Click the cur ve where you want to add the
point.
A point is added at the location you clicked.
The curvature can change.
To a d d a poi nt a n d extend t he l engt h of a cur v e:
1.
ClicktoturnonExtend.
2. Move the mouse over a point curve. The curve
ishighlightedinblue,andoneofthecurve’s
ends displays a box to show where the curve
will be extended.
3. Drag from the hig hli g hted end p oint, and then
release the mouse button.

To add points to a point surface:
1.
In the Refine group box, click Surf Row, Surf
Col., or Surf Row & Col.
2. Click the surface.

thepointwhereyouclickedthesurface. The
new points are placed on the surface so they
preserve the surface’s c urvature. The curvature
can change, but only slightly.
To fuse two points:
1.
Tur n o n Fuse .
2. Click a point without releasing the mouse
button. Drag to another point, and then release
the mouse button.
Thefirstpointyouchooseacquirestheposition
of the second point, and becomes dependent to
it. If the first point has an animation controller,
the controller is discarded. If the second point
has an animation controller, the first point
acquires it too .
Fused points display in purple by default.
To unfuse fused points:
1.
Select the fused point.
2. Click Unfuse.
Now you can move and edit the two points
independently.
To tr ansfor m a regi on:
1.
Using sub-object selection, select one or more
points for the center of transformation.
2. Turn on Soft Selection.
3. Transfor m the p oi nt.

transformed accordingly.
Move is the most common transform to use.
Rotate and Scale can be used w ith a non-local
transform center.
Tip: If Soft Selection appears not to be working,
the Falloff value might b e too small for the size
of your surface. On the
Soft Selection rollout
(page 1–1148)
, increase the value of Falloff so it
encompasses other points.

In addition to the Point rollout described here,
the Point sub-object level also displays the
Soft
Selection rollout (page 1–1148)
.
