geometry in your scene. In addition to these units,
the software also uses system units as an internal
mechanism. System units should only be changed
before you create your scene or import a unitless

You can also set the lighting units using this dialog .
System vs. Display Units
It is important to note the distinction between
System and Display units. Display units only

System units determine the actual scale of
geometry. For example, if you import a DXF file
(unitless) containing a 1 x 1 x 1 Box, 3ds Max may
import the box’s dimensions in inches or miles,
depending on the System unit. This can have a
significant impact on your scene, which is why you
should always set up the system unit
before you
import or create geometry.
