Point Curve 1111
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 Angle 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 lock
the aspect ratio. When Lock is turned on, Width
is locked to Depth that results in a constant ratio
of Width to Depth.
Lengt h—Specifies the size of the cross–section
along the local
Y
axis.
Width—Specifies the size of the cross–sect ion
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
canuseAngletopositiona"flat"sidedown.
Auto S mooth—If Auto Smooth is tu rned on,
the spline is auto-smoothed u s ing the threshold
specified by the Threshold setting below it. Auto
Smooth sets the s moothing based on the ang le
between spline segments. Any two adjacent
segmentsareputinthesamesmoothinggroupif
the angle between them is less than the threshold
angle.
Threshold—Specifies the threshold angle in
degrees. Any two adjacent spline seg ments are put
inthesamesmoothinggroupiftheanglebetween
them is less than the threshold angle.
Keyboard Entry rollout
The Keyboard Entry rollout lets you create a
NURBS curve by typing. Use the TAB key to move
between the controls in this rollout. To click a
button from the keyboard, press ENTER while the
button is active.
X, Y, and Z—Let you enter the coordinates of the
next point to add.
Add Point—Adds the point to the curve.
Clo se—Ends creation of the curve and creates
a segment between the last point and the initial
point to close the curve.
Fin is h —Ends creation of the curve, leaving it open.
Create Point Cur ve rollout
This rollout contains the controls for curve
approximation.
Interpola t io n group
The controls in this grou p box change the accuracy
and type of
curve approximation (page 1–1240)
used to generate and display the curve.
