Turns on spatial indexing. An integer of up to five digits
is valid. The first three digits refer to model space, and the
remaining two digits refer to paper space.
>0
Treats model space objects as 2D (Z coordinates are ig-
nored), as is always the case with paper space objects.
<0
Such a setting is appropriate for 2D drawings and makes
more efficient use of memory without loss of performance
NOTE You cannot use TREEDEPTH transparently.

10000000Initial value:
Limits memory consumption during drawing regeneration by limiting the
number of nodes in the spatial index (oct-tree).
By imposing a fixed limit with TREEMAX, you can load drawings created on
systems with more memory than your system and with a larger TREEDEPTH
than your system can handle. These drawings, if left unchecked, have an
oct-tree large enough to eventually consume more memory than is available
to your computer. TREEMAX also provides a safeguard against experimentation
with inappropriately high TREEDEPTH values.
The initial default for TREEMAX is 10000000 (10 million), a value high enough
to effectively disable TREEMAX as a control for TREEDEPTH. The value to
which you should set TREEMAX depends on your system's available RAM.
You get about 15,000 oct-tree nodes per megabyte of RAM.
If you want an oct-tree to use up to, but no more than, 2 megabytes of RAM,
set TREEMAX to 30000 (2 x 15,000). If the program runs out of memory
allocating oct-tree nodes, restart, set TREEMAX to a smaller number, and try
loading the drawing again.
