There are only single option for animation in Animation tool Bar "Transforms Component"
This tool only transforms component as treating there is no relation between components as we have already given in Model Environment of Assembly.
What about those joint we have given in Model Environment. There should be an animation tool in animation tool bar which can provide component motion as per given in Model Environment of Fusion 360. We can read a motion of joint in Model Environment only.
These Joint relation should be maintained in Animation Environment also. So that previously Known Relation of joint can also be animated in Animation Environment of Fusion 360...
