Rotating a part in an assembly around a shaft not aligned to the coordinate system

ricardo_raimondo

I am assembling an airplane wing with its aileron. I have the wing fixed. Both parts have a shaft, that acts as the hinge between the parts. I Used the cylindrical mate to align both shafts and a planar mate to align the end of both shafts. Now, when I select the aileron and try to rotate it around the shaft, it doesn't move. It looks that this is because the moving arrows that appear when I select the aileron are not aligned with the coordinates system. If I unfix the wing, then there is rotation, but also lateral displacement of the wing. Can someone help me, please?

you said 'unfix' the wing.
if you have anything FIXED then it will not move at all.

it sounds like you need to fix the fuselage and mate everything to that.
There should only be 1 fixed part per assembly. Use group mate to combine multiple parts to the fixed part.

Thank you for your comments. I think I was not clear in my text. Following your text; I do have the wing and aileron each defined as a group. I have the wing fixed. I mated the aileron to the wing with a cylindrical mate. 
I think I just found the problem. It seems that I have to move the movement control arrows to the center of the cylinder used for the mate. Will check further into it to be 100% sure.

I would start by weeding out the unnecessary planar mate. Use a revolute which gives the same result as the planar and cylindrical combo but tells onshape more directly what your doing. Then, after you select the aileron, grab the center point of the manipulator.  If you drag it over the shaft of the aileron, it will attach and reorient itself to a new coordinate system that is relative to the implicate connector it snapped to. This should provide onshape with more direct instruction on exactly how you want the item to move.
