Selec t Vertices By group
Co lor/Ill umination—These r adio buttons let you
choose to select vertices by vertex color value or
vertex illumination value. Set the desired options
and then click Select.
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 which radio button is
selected, selects a l l vertices whose vertex color or
illumination values either match the color swatch,
or are within the range specified 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 swatch in Select By Vertex
Color, or be within a range determined by adding
and subtracting the Range values from the
displayed color. Defa ult=10.
For example, if you’ve chosen Color and set the
color swatch to medium gray (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 vert ices. Two
faces can share a single edge.
At the Editable Mesh (Edge) sub-object level, you
can select single and multiple edges and transform
them using standard metho ds.

Procedure
To create a sha pe f r om one or mor e 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 cur ve name or keep the default.
• ChooseSmoothorLinearastheShapeType.
• TurnonIgnoreHiddenEdgestoexclude
hidden edges from the calculation, or turn
this feature 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 ver tices using smooth values,
while the Linear option results in linear splines
with corner vertices.
When you region-select edges, al l 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 edges in the calculation.
If the selected e dges are not continuous, 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
