Use this menu to specify the units to which you want to convert your exported scene. Modifying this setting directly affects the Scale Factor value applied to the exported data.
The plug-in determines the default units by looking at the System Unit Scale in the System Unit Setup dialog box in 3ds Max.
To view the default units, click System Unit Setup in the Units Setup dialog box that appears when you select Units Setup from the 3ds Max Customize menu.
On export, the plug-in applies no default scaling since the export and system units match. This results in a Scale Factor of “1.0”.
For information about incorrect or unwanted scaling issues, see Why is my scene scaled differently in 3ds Max?.
If you export a file that is in the same unit setting as the System Units of your 3ds Max scene, there is a match of units and the displayed Scale Factor will be “1.0”. No scale conversion is applied.
A unit match, with a Scale Factor of 1.0
