Fusion 360 to blender - FBX cleanup & fix transforms

I did Autodesk job :

This Blender addon will help you with the infamous scales problems that F360 makes with multi parts FBX models. You will also be able to:

• Apply the scale of every empties and objects, so everything is 1. It will work also on multi user objects, keeping the instances alive !
• Manage the size and appearance of empties depending on their position in the chain of components.
• suppress redundant empties and empties that hold only one object (with the possibility to copy the name to the object).
• suppress empties you don't need (case by case tweak), and all the child objects will be reparented to the empty just above.

On a fairly complex model, you are almost guarantied to divide by 2 or 3 the number of objects just by deleting junk empties !
