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

using the Tiling parameters in the applied material.

when Enable in Viewport is turned on.
Radial—Displaysthesplineasa3Dobjectwith
a circular cross-section.
•
Thick ness—Specifies the cross-section diameter.
Default=1.0. Range=0.0 to 100,000,000.0.
•
Sides—Sets the number of sides for the spline
mesh in the viewports or renderer. For example,
a value of 4 produces a square cross-section.
•
Angle—Adjust the rotational position of the
cross section in the viewports or renderer. For
example, if you have a square cross sec t ion you
canuseAngletopositiona“flat”sidedown.
Rectangular—Displaysthesplineasa3D
object with a rectangular cross-sect ion.
•
Lengt h—Specifies the size of the
cross–section along the local
Y
axis.
•
Width—Specifies the size of the
cross–section along the lo c al
X
axis.
•
Angle—Adjusts the rotational position of the
cross-section in t he viewport or renderer. For
example, if you have a square cross-section you
can use Angle to position a "flat" side down.
•
Aspect—Sets the aspec t r atio for rectangular
cross-sections. The Lock check box lets you
lock the aspect ratio. When Lock is turned
on, Width is locked to Depth that results in a
constant ratio of W idth to Depth.
Auto Smooth—When on, the spline is
auto-smoothed using the s moothing angle
specified by the Threshold setting. Auto Smooth
sets the smoothing based on the angle between
spline segm ents. Any two adjacent s egments a re
put in the same smoothing group if the angle

Note: Turning Auto Smooth on for every situation
doesnotalwaysgiveyouthebestsmoothing
quality. AlteringtheThresholdanglemaybe
necessar y or turning Auto Smooth off may
produce the best results.
Threshold—Specifies the threshold angle in
degrees. Any two adjacent spline segments are
placed in the same smoothing g roup if the angle
betweenthemislessthanthethresholdangle.
