At the Editable Patch
(Vertex) level, you can select single and multiple vertices and
move them using standard methods. You can also move and rotate
thus affecting the shapes of any patches connected to the vertex.
To transform either vertices or vectors:
- At Patch (Vertex) level, with Selection
turned on, select vertices in the patch
object you want to transform.
Vertices and their vectors
- 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
can toggle between filters to alternatively transform either component.
To switch vertex types:
- Right-click a patch vertex.
- 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 vertex causes the opposite vectors
to adjust 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 vertex types from Coplanar
to Corner, do one of the following:
- Hold down Shift as
you move a handle of a Coplanar vertex.
This changes the vertex
type to Corner.
If Lock Handles is off
(the default), Shift+Move "breaks"
the handle, allowing it to move independently.
If Lock Handles is on,
the handles remain locked in their coplanar relationship. However,
the vertex is still switched to Corner, and turning off Lock Handles
lets you move the handles separately.
- Right-click the vertex and then choose
Corner from the quad menu.
To delete a vertex:
- At Patch (Vertex) level, select a vertex.
- Click Delete.
The vertex and all patches
sharing this control point are deleted.
To weld vertices:
- At Patch (Vertex) level, select two valid vertices
on different patches.
- Set Weld Threshold to a value at least
equal to the distance between the selected vertices.
- Click Selected.
The two vertices move
together and join.
To transform interior vertices:
Using program defaults,
you can select only vertices and vectors on the outer edge or boundary
of a patch. This default is known as Auto Interior.
In some cases, you might
want to move the interior vertices. For example, you might want
to tweak a patch's curvature without having to subdivide the patch.
you can change the default on a patch-by-patch basis by right-clicking
a patch and choosing Manual Interior from the shortcut menu. This
lets you select and transform individual interior vertices. These
vertices appear as yellow squares in the viewports.
WarningIf you return a patch
to the default, changes due to Manual Interior are lost.
NoteCertain objects are
automatically set to Manual Interior when converted to patch objects.
In such cases, you can see all interior vertices when you go to
the Vertex sub-object level.

Edit Vertex Colors group
Use these controls to
assign the color, illumination color (shading), and alpha (transparency)
values of selected vertices.
Click the color swatch
to change the color of selected vertices.
Click the color swatch
to change the illumination color of selected vertices. This lets
you change the color of shadows without changing the vertex colors.
Lets you assign an alpha (transparency)
value to selected vertices.
The spinner value is
a percentage; zero is completely transparent and 100 is completely opaque.
Select Vertex By group
- Color and Illumination radio buttons
These buttons determine whether
to select vertices by vertex color values or vertex illumination
- Color Swatch
Displays the Color Selector,
where you can specify a color to match.
Depending on which radio
button is selected, selects all vertices whose vertex color or illumination
values either match the color swatch, or are within the range specified
by the RGB spinners.
Specifies a range for
the color match. All three RGB values in the vertex color or illumination
must either match the color specified by the Color swatch in Select
By Vertex Color, or be within plus or minus the values in the Range
