Asset Importers for models default the Scale Factor value to 1 regardless of the model extension
How to reproduce:
1. Download the user-submitted model(1x1x1cube.jas)
2. Create a new Unity project
3. Import the downloaded model
4. Select it in the Project View and see the import settings
Expected result: Scale Factor is defaulted to a value, appropriate for the asset extension(in this case - 0.01 for .jas)
Actual result: Scale Factor always defaults to 1
Reproducible with: 2017.4.31f1, 2018.4.6f1, 2019.1.14f1, 2019.2.1f1, 2019.3.0a12

Resolution Note (2020.1.X):
Cheetah3D does not have a precise definition of its unit. In Unity, when the fbx conversion is done to import the asset, the fbx sdk reports it as a meter unit. In 2017 we fixed our scripts to use what is being declared in the fbx sdk value instead of a fixed custom value, hence the size change in newly imported Cheetah files.
We do not want to introduce any new custom values in this conversion process and it will stay with the current scale factor.
The documentation and manual does not mention the custom scale values since the 2017 version of Unity, which matches the current behavior.
However, it is possible to create a default partial Preset applied to all .jas files that would set the global scale factor to 0.01 and get the older behavior back in your project.
