Change joint origin orientation?

[derekmcleod]

I'm working on an organic shaped light fixture that has 3d spline sketch derived 'branches' and then many points of light attached along the branches. I've made the points of light which are globes in three sizes as subassemblies within component groups.

When I am using rigid joints to attach the globes to the branches, I occasionally want to modify the orientation with a joint origin. I've created sketch points along the path to locate the joint origins. Within joint origin, the reorient option allows for Z and X axis alignment, when what I really want is something in between, given the organic nature of this thing. I can also rotate the origin, but only in one plane. I suppose what I would like is the capabilities of move within the joint origin command.

Would construction axes be another way to get the kind of nuance I am after?

Or use move and then rigid group? 

Thanks!

Have you experimented with a ball joint rather than a rigid?

Using sketches might be easier than construction axis. 

Just to get you thinking.

Here the line pointed to by the red arrow is the natural Z the joint origin would use but I've sketched a line then added a plane at angle then sketched a line at an angle to what would have been the Z. So you could rotate the plane and adjust the angle of the line to make the joint origin point anywhere and rotate the joint origin. Actually don't suppose the joint origin is needed.
