The reactor Plane object is a type of rigid body that acts as a fixed, infinite
plane in the simulation. It shouldn't be confused with the standard 3ds Max
plane, which can also be used as a rigid body provided its
simulation geometry
property
on page 3914 is set to Concave Mesh.
Like other rigid bodies, the Plane can have display proxies assigned to it and
can be contained in a compound rigid body. You can also assign friction and
elasticity values to it. However, it is always fixed in the simulation (the
Mass
on page 3912 and Unyielding on page 3912 properties are ignored).
The reactor Plane acts in only one direction, as shown in the viewport by an
arrow pointing away from its solid surface. This means that rigid bodies
approaching the plane from the "wrong" direction pass through it. You can,
of course, also use two opposing planes.

Procedures
To create a Plane:
1 Choose one of the above options, and then click in any viewport.
The plane’s normal is aligned with the viewport’s Z axis.
2 Use the Move and Rotate tools to adjust its position and orientation, as
necessary.
