Fusion 360 -> Unreal Studio Joints?

Is it possible to import joints from Fusion 360 into Unreal Studio?

Not at this time. It’s a workflow we’d like to support (basic rigid-body mechanics).

In the meantime is there any way to identify the location of a joint in an imported IGES, SAT, or STEP file format? These appear to be the file formats that F360 can export and Unreal Studio can import. I think if I can easily access those points I should be able to make something workable with blueprint.
