How does terrain scale effect other 3d assests

Hello all,

I have been tasked with creating a large environment for
a training simulation.

From what I understand the default Terrain Square Size of 8 yields
a terrain at approximatley 1.6 km by 1.6 km.

I need an environment measuring 6 km by 6 km.

I read that increasining the Terrain Square Size to 32 will meet
this requirement, but I am unclear on how this will effect
the scale of the buildings, roads, and models that will be
placed in this environment.

I use 3ds max to create structures, exporting them to a .map
file. I use Valve Hammer to scale and tile the textures on the
blocks and then create the .dif from Valve.

When I build structures in 3ds max, I am working with 32 units
equalling 1 Torque unit, which is 1 meter. The map file has
a geometry scale parameter set to 32 so when the map file
is compiled into a .dif, the structure will be scaled down to
match torque units.

What I am unclear about is whether increasing the Terrain Square size
to 32 will effect the scale of the .difs that I am creating. In other words
if I make a cube measuring 32x32x32 units in 3ds max and then
create a .dif from that cube will that cube still be 1x1x1 meters?

If not, what will be the size, in torque units, of that cube.

Thanks in advance for help with this question,
