File Load: Units Mismatch Dialog
Change the system unit scale. > Open, Merge, XRef, or
drag geometr y from a file with a different unit scale.
This dialog appears when you open or merge a file
that has b een saved with system unit settings that
aredifferentfromthoseofyourcurrent3dsMax
session. The default system unit setting is Inches.
If you open a file with the system unit set to meters,
for example, you will see this dialog.
When t his happens, you have two options:
• Rescale t he File Objects to the System Un it
Scale: You can choose to rescale the objects
fromtheincomingfiletomatchthecurrent
system unit. This changes the size of the
incoming geometry
• Adopt the File’s Unit Scale: This changes the
system unit in your 3ds Max installation to
match that of the incoming file. This setting wil l
persist between the current an d future 3ds Max
sessions until you reset your system unit (page
3–850).Thisisthedefaultoption.
Choosing File > Reset will not reset your
system unit. You must either change it using
Customize > Units Setup > System Unit Setup,
or manually edit your 3dsmax.ini file.
Note: This dialog appears only if Respect System
Units In Files is turned on in the System Unit Setup
dialog (page 3–850).
Interfa ce
Rescale the File Objects to the System Unit S cale—
Objects f rom the file are rescaled to the current
session’s system unit sca le.
Note: Many features depend on the scale of the
scene, so cho osing to rescale the file objects can
have unpredictable results, par ticularly in scenes
using radiosit y. Reset and recalculate radiosity if
you have rescaled the file objects.
Tip: Use the Zoom Extents All button if the
geometry is no longer visible in the viewport after
rescaling.
Adopt the File’s Unit S cale—The system unit scale
is changed to match that of the other file. T his is
the default option.
Choosing Adopt The File’s Unit Scale adds two
settings to your 3dsmax.ini file: UnitType=
and UnitScale=. For this reason, this change
is persistent between sessions until you reset it
manually.
TogetbackthedefaultSystemUnitScale,you
can edit your 3d smax.ini file and remove those
settings; or go to Customize > Units Setup >
System Unit Setup and change the units back to
the default scale, Inches.
