I can't display the length after the line is drawn, but I've already checked the "length" option

I can’t display the length after the line is drawn, but I’ve already checked the “length” option.My version is slicer 5.6.1 apple version

Are you by chance using SlicerMorph? Or trying to use undo/redo functionality for Markups module objects which includes the Line object?

This seems reminiscent of the following post:

Markups tools not measuring Slicer 5.4.0

@jmhuie what do you mean by stops measuring? I am trying to replicate this on an intel Mac I have, and line tools works as expected, but it doesn’t display the measurement field regardless whether slicermorph customization are enabled or disabled? Is this what you are referring to as the issue? We did recently enabled undo for markups through the customization script, but I am not seeing any errors in the log file either. @smrolfe [image]

However the above resulted in a change to the SlicerMorphRC file which should be used in the latest Slicer 5.6.1 assuming you re-installed SlicerMorph using the Slicer extensions manager which pulls the latest from the internet.

I can confirm that in 5.6.1 if the SlicerMorph customizations are used, undo is only enabled for fiducial objects, and measurements are displayed correctly for line objects.
