when Enable In Viewport is on.
Genera te Mappi ng Coords—Turn t his on to appl y
mapping coordinates. Default=off.
3ds Max generates the mapping coordinates in
the U and V dimensions. The U coordinate
w raps once around the spline; the V coordinate is
mappedoncealongitslength.Tilingisachieved
using the Tiling parameters in the applied material.
For more information, see
Mapping Coordinates
(page 2–1249)
.
Real-World Ma p Size—Controls 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.
Auto Smooth—If Auto Smooth is turned on,
the spline is auto-smoothed using the threshold
specified by the Threshold setting below it. Auto
Smooth sets the smo othing based on the angle
between spline segments. Any two adjacent
segmentsareputinthesamesmoothinggroupif
the ang le between them is less than the threshold
angle.
Threshold—Specifies the threshold angle in
degrees. Any two adjacent spline segments are put
inthesamesmoothinggroupiftheanglebetween
them is less than the threshold angle.
Viewport—Turn this on to specify Radial or
Rectangular parameters for the shape as it will
display in the v iewport w hen Enable in View por t
is turned on.
R end er er—Turn this on to specify Radial or
Rectangular parameters for the shape as it will
displaywhenrenderedorviewedintheviewport
when Enable in Viewport is turned on.
Radial—Displays the 3D mesh as a cy lindrical
object.
Thickness—Specifies the diameter of the viewpor t
or rendered spline mesh. Default=1.0. Range=0.0
to 100,000,000.0.
Splines rendered at thickness of 1.0 and 5.0, respectively
Sides—Sets the number of sides (or facets) for
the spline mesh n the viewport or renderer.
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 ca n use Angle to pos ition a "flat" side
down.
Rectangular—Displays the spline’s mesh shape
as a rectangle.
Length—Specifies the size of the cross–section
along the lo cal
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 s quare cross-section you
can use Angle to position a "flat" side down.
Aspect—Sets the aspect ratio for rectangular
cross-sections. The Lo ck check box lets you lock
the aspect ratio. When Lock is turned on, Width is
locked to Length that results in a constant ratio of
Width to Length.
