Invert the weld note in 3D

Hi all,

My problem is only in the visualization of the 3D notes within the weld environment.

I've setted the view plane and the orientation of te text in the

View -> Annotation orientation

When I make a weld, sometime the foot of the arrow is on the right side, sometime not; and then I'm not able to invert the side of the text.

How can I do?

Thanks
