AttheEditablePatch(Vertex)level,youcanselect
single and multiple vertices and move them using
standard methods. You can also move and rotate
vector hand les (page 3–1123) ,thusaffectingthe
shapes of any patches connected to the vertex.

Totransformeitherverticesorvectors:
1.
At Patch (Vertex) level, with Sele ction rollout >
Filter group > Vertices tur ned on, select vertices
in the patch object you want to transform.
Vertices and their vectors both appear.
2. Turn off one of the filters, leaving the other on,
and choose a transform.
A transform cursor appears when you move
onto a vertex or vector in the selection set.
You c an toggle between filters to a lternatively
transform either component.
To switch vertex ty pes:
1.
Right-click a patch vertex.
2. Choose from commands on the quad menu.
The Tools 1 (upper-left) quadrant includes two
options specific to patch vertices:
• Coplanar: If you set a patch control point’s
property to be coplanar, it’s like locking the
handle of the outgoing vector for that point.
Moving a handle attached to a coplanar
vertexcausestheoppositevectorstoadjust
their positions to maintain a coplanar
surface. This option is the default and gives
smooth transitions between patches.
• Corner: If you set a patch control point’s
property to be corner, it unlocks the handle
of the outgoing vector, so you can create a
discontinuous break in the patch surface.
To switch ver tex t ypes from Coplanar to Corner, do
one of the fol lowing:
1.
Hold down SHIFT as you move a handle of a
Coplanar vertex.
This sw itches the vertex type to Corner.
IfLockHandlesisturnedoff(thedefault),
SHIFT+Move "breaks" the handle, allowing it
to move independently.
IfLockHandlesison,thehandlesremain
locked in their coplanar relationship. However,
the vertex is sti ll switched to Corner, and

handles separately.
2. R ight-click the vertex, and choose C orner from
the quad menu.
To delete a vertex:
1.
At Patch (Vertex) level, select a vertex.
2. Click Delete.
The vertex and all patches sharing this control
point are deleted.
