Left: The quarter-round secti on is set to zero steps.
Right: The same sec t ion on the right is set to four steps.
Steps—Sets the number of divisions, or steps,
the program uses between each built-in section’s
vertices. Splines with t ig ht curves require many
steps to look smooth while gentle curves require
fewer steps. Range=0 to 100.
Spline steps can be either adaptive or manually
specified. The method used is set by the state of
theAdaptiveswitch. Themainuseformanual
int erpolation is to create splines for morphing
or other operations where you must have exact
control over the number of vertices created.
Optimi ze—When on, removes unneeded steps
from st raight segments in the spline. Default=on.
Note: Optimize is not available when Adapt ive is
on.
Left: Optimize is on for the left-hand sweep.
Right: Optimize is off for the right-hand sweep.
Adaptive—When on, automatically sets the
number of steps for each spline to produce a
smooth curve. Straight segments always receive
0 steps. When off, enables manual inter polation
control using Optimize and Steps. Default=off.
Parameters rollout
The Parameters rollout is context-sensitive and
displays different settings depending upon the
built-in sec tion you’ve chosen to sweep a long a
spline. For example, more complex sections such
as the Angle have seven settings that you can
change whereas the Quarter-Round has only one
setting.
Parameters rollout – Angle
Lengt h—Controls the height of the vertical leg of
the angle section. Default=6.0.
Width—Controls the width of the horizontal leg of
the angle section. Default=4.0.
Thickness—Controls the thickness of both legs of
the angle. Default=0.5.
Sync Corner Fillets—When turned on, Corner
Radius 1 controls the radius of both the interior
and exterior corners b etween the vertical and
horizontal legs. It also maintains the thickness of
the section. Default=off.
Co rn er Radius 1—Controls the exterior radius
between the vertical and horizontal legs of the
angle sec tion. Default=0.0.
Co rn er Radius 2—Controls the interior radius
between the vertical and horizontal legs of the
angle sec tion. Default=0.5.
