Selec t Vertices By group
Co lor/Illuminatio n—These radio buttons let you
choose to select vertices by vertex color value or
vertex illumination value. Set the desired options
and then click Selec t.
Co lor Swatch—Displays the current color to match.
Click to open the Color Selector, w here you can
specify a different color.
Select—Depending on w hich radio button is
selected, selec ts all vertices whose vertex color or
illumination values either match the color swatch,
or are within the range spec ified by the RGB
spinners.
Range—Specifies a range for the color match.
All three RGB values in the vertex color or
illuminationcolormusteithermatchthecolor
specified by the Color swatc h in Select By Vertex
Color, or be within a range determined by adding
and subtracting the Range values from the
displayed color. Default=10.
For example, if you’ve chosen Color and set the
color swatch to medium gr ay (R=G=B=128), and
are using the default Range values of 10,10,10,
then clicking the Select button selects only vertices
set to RGB color values between 118,118,118 and
138,138,138.

An edge is a line, visible or invisible, forming the
side of a face and connecting two vertices. Two
faces can share a single edge.
At the Editable Mesh (Edge) sub-objec t level, you
can select single and multiple edges and transform
them using standard methods. This topic covers
the Edit Geometry rollout; for other controls, see
Editable Mesh (page 1–984) .
Procedure
To creat e a sha pe fr om one or more edges:
1.
Selecttheedgesyouwanttomakeintoshapes.
2. On the Edit Geometry rollout, click Create
Shape From Edges.
3. Make changes, as needed, on the Create Shape
dialog that appears.
• Enter a curve name or keep the default.
• ChooseSmoothorLinearastheShapeType.
• TurnonIgnoreHiddenEdgestoexclude
hidden edges from the calculation, or turn
this feat ure off.
4. Click OK.
The resulting shape consists of one or more
splines whose vertices are coincident with the
vertices in the selected edges. The Smooth
option results in vertices using smooth values,
while the Linear option results in linear splines
with corner vertices.
When you region-select edges, all edges are
highlighted, including hidden edges, which
are displayed as dashed lines. As a default,
the Create Shape function ignores the hidden
edges, even though they’re selected. Turn off
Ignore Hidden Edges if you want to include the
hidden e dges in the calculation.
If the selected edges are not cont inuous, or if
they branch, the resulting shape will consist
of more than one spline. When the Create
Shape function runs into a branching ’Y’ in
the edges, it m a kes an arbitrary decision as to
which edge produces which spline. If you need
to control this, select only those edges that will
