Torus Primitive 175
Parameters rollout
The defaults produce a smooth, round tube of
18 sides with the pivot point at the center of the
base.Therearefiveheightsegmentsandonecap
segment. If you don’t plan to modify the cylinder’s
shape, such as with a Bend modifier, set Height
Segments to 1 to reduce scene complexity. If you
plan to modify the ends of the cylinder, consider
increasing the Cap Segments setting.
Radius 1, R adius 2—The larger setting specifies
theoutsideradiusofthetube,whilethesmaller
specifies the inside radius.
Height—Sets the dimension along the central
axis. Negative values create the tube below the
construction plane.
Height S egments—Sets the number of divisions
along the tube’s major axis.
Cap Seg m en ts—Sets the number of concentric
divisionsaroundthecenterofthetube’stopand
bottom.
Sides—Sets the number of sides around the tube.
Higher numbers shade and render as true circles
with Smooth on. Lower numbers create regular
polygonal objects with Smooth off.
Smooth—When on (the default), faces of the
tube are blended together, creating a smooth
appearance in rendered views.
Slice On—Enables the Slice feature, which removes
part of the tube’s circumference. Default=off.

Slice From, Slice To—Sets the number of degrees
around the local Z axis from a zero point at the
local X axis.
For both settings, positive va lues move the end of
the slice counterclockwise; negative values move it
clockwise. Either setting can b e made first. When
the ends meet, the whole tube reappears.
Gener ate M apping Coords—Generates coordinates
for applying mapped materials to the tube.
Default=on.
Real-World M ap Size—Cont rols the scaling
