Hi all,

I’m trying to retrieve the cursor’s RAS position using the following code:

```auto
ras = [0, 0, 0]
crosshairNode.GetCursorPositionRAS(ras)

```

In **Slicer 5.6** , when the cursor was positioned over the `modelNode`, it would return the coordinates on that `modelNode`. However, in **5.7** , even when the cursor is over the `modelNode`, it instead returns coordinates from the camera plane.

Could you please let me know if there were any updates or changes in this new version that could explain this behavior?

Thank you!

Thank you for the response @Sunderlandkyl.  
Is there a way to resolve this issue in Python before the pull request is merged?
