Hello

When I switch between “World” and “Local” in the “Coordinates:” drop down list of the Control Points section of the Markups module, the coordinates are not automatically updated.

As workaround one can use the “Previous Modules” and “Next Modules” buttons once. Then the coordinate values are updated.

However, I assume this is not the intended behavior.

Tested with 3D Slicer 5.6.2 r32448 / f10cd8c

Kind regards

Thank you, good catch. I’ve submitted an issue and tentatively scheduled to be fixed before the next stable release (that is due end of next week), but maybe it will be fixed later:
