I'm very new to blender so sorry if I say stupid things.
I am trying to put a series of splines along a circumference (at different distances so I can't use duplication... I suppose)
For easiness I set the origin of the splines at the center of the circumference with CtrlAltShiftC "Origin to 3D Cursor" but when I try to "move" one single spline along the circumference (rotating with RZ) even the other splines are moving with the selected one.
Edit: I've switched off proportional editing but still doesn't work.
