Hi all,  
if I measure a length or an angle with Slicer I can read the value only in the 3D view.  
Is there any possibility to show it also in the 2D view?

Thanks a lot,  
Paolo

In recent Slicer preview releases, you see values in both in slice and 3D views. You can also see them in Markups module (description column).

Thanks @lassoan.  
Markups module does this, but if I use the ruler on the top bar it has not the same behavior (it doesn’t show the value).  
I mean, for me it’s fine, it’s just to highlight this difference.

We’ll remove Annotations module soon. It has many issues and limitations.
