When on, the shape is
rendered as a 3D mesh using the Radial or
Rectangular parameters set for Renderer. In
previous versions of the program, the Renderable
switch performed the same operation.
Enable In Viewpor t—When on, the shape is
displayedintheviewportasa3Dmeshusingthe
Radial or Rectangular parameters set for Renderer.
In previous versions of the program, the Display
Render Mesh performed the same operation.
Use V iewpor t settings—Lets you set different
rendering parameters, and displays the mesh
generated by the Viewport settings. Available only
when Enable in Viewport is turned on.
Genera te M a pping Coords—Tur n t his on to app ly
mapping coordinates. D efault=off.
The U coordinate wraps once around the thickness
of the spline; the V coordinate is mapped once
along the length of the spline. Tiling is achieved
using the Tiling parameters in the material itself.
Real-World M ap Size—Cont rols the scaling
method used for texture mapped materials that
are applied to the object. The scaling values are
cont rolled by the Use Real-World Scale settings
found in the applied material’s
Coordinates rollout
(page 2–1434)
.Default=on.
Viewport—Tur n this on to specify Radial or
Rectangular p arameters for the shape as it w i ll
display in the viewport when Enable in Viewport
is turn ed on.
R end er er—Turn this on to specify Radial or
Rectangular p arameters for the shape as it w i ll
displaywhenrenderedorviewedintheviewport
when Enable in Viewport is turned on.
Radial—Displays the 3 D mesh as a cylindrical
object.
Thick ness—Specifies the diameter of the viewport
or rendered spline mesh. Default=1.0. Range=0.0
to 100,000,000.0.
Splines rendered at thick ness of 1.0 and 5.0, respectively
Sides—Sets the number of sides (or facets) for
thesplinemeshntheviewportorrenderer.For
example, a value of 4 results in a square cross
section.
Angle—Adjusts the rotational position of the
cross-section in the viewport or renderer. For
example, if the spline mesh has a square cross
section you can use Angl e to position a "flat" side
down.
Rectangular—Displays the spline’s mesh shape
as rectangular.
Aspect—Sets the aspect ratio for rectangular
cross-sections. The Lock check box lets you lo ck
the aspect ratio. When Lock is turned on, Width
is locked to Depth that results in a constant ratio
of Width to Depth.
Length—Specifies t he size of the cross–sect ion
along the loca l
Y
axis.
Width—Specifies the size of the cross–section
along the local
X
axis.
Angle—Adjusts the rotational position of the
cross-section in the viewport or renderer. For
example, if you have a square cross-section you
can use Angle to position a "flat" side down.
Auto S mooth—If A uto Smooth is turned on,
thesplineisauto-smoothedusingthethreshold
specified by the Threshold setting below it. Auto
Smooth sets the s moothing based on the angle
between spline segments. Any two adjacent
