Slice From, Slice To—Sets the number of degrees
around the local Z axis f rom a zero point at the
local X axis.
For b oth settings, positive va lues move the end of
the slice counterclockwise; negative values move it
clockwise. Either se tting can be m ade first. When
the ends meet, the w hole cone reappears.
Genera te M apping Coords—Generates coordinates
for apply ing mapped materials to the cone.
Default=on.
Real-World Map Size—Controls the scaling method
used for texture mapped materials that are applied

by the Use Real-World Scale settings found in
the applied material’s Coor dinates rollout (page

Sphere produces a f ull sphere, or a hemisphere or
other portion of a sphere. You can also "slice" a
sphere about its vertical axis.
Examples of spheres
Procedures
To create a spher e:
1.

Primitives > Sphere.
2. In any viewport, drag to define a radius.
As you drag, a sphere emerges with its center
at the pivot point.
3. Releasethemousetosettheradiusandcreate
the sphere.
To create a hemispher e:
You can reverse the order of the follow ing steps,
if you like.
1. Create a sphere of desired radius.
2. Ty pe 0.5 in the Hemisphere field.

a hemisphere. If you use the spinner, the sphere
changes in size.

Edge—Draws a sphere f rom edge to edge. You can
change the center location by moving the mouse.
Center—Draws a sphere from the center out.
