I take fusion models and import them as STL files into my simulation (read: game) software.
The simplest way for me to animate them is when the part origin is on an axis of rotation. Sometimes developers design parts where this is not the case.
I wish I could add a point at the correct location and say "now export the model with point P as the origin". Just as good would be to move the origin itself without rebuilding everything.
Please and thank you!
