The **about
<center_spec>** context is the MAXScript
equivalent of the rotate/scale transform center list on the
main **3ds
Max** toolbar. It defines the
center point about which any scale or rotation operation is
performed within its context. Note that, like the center list
in **3ds
Max**, this sets only the
center **point**
for
the operation, not the axis. The axis is taken from the current
working coordinate system set using the **coordsys**
context
expression:

**about
selection**

rotates/scales about the center of the current selection

**about
pivot**

rotates/scales about each object's pivot point

**about
coordsys**

rotates/scales about the
center of the current working coordinate system set using
the **coordsys**
context
expression

**about**
<node>

rotates/scales about the pivot point of the given object

**about**
<matrix3>

rotates/scales about the center of the coordinate system specified by the given 3D matrix

**about**
<point3>

rotates/scales about the given point with coordinate system and axes taken from the current working coordinate system.

*
Examples:*

-- rotate all the boxes 30 degrees about the y_axis of $foo

about $foo rotate $box* 30 y_axis

-- rotate each planet 45 degrees around its parent

in coordsys parent about coordsys rotate $planets* 45 z_axis
