How to display the crosshair in a single view through the steps shown in the figures below.

Is there a corresponding interface through the program?  
Thanks,

> Crosshair and slice intersections are two different things. Slice intersections will not appear if you only have one slice view in the view layout. If you enable crosshair display, it will be always visible in the slice and 3D views, regardless of what layout you use.

have you considered using the “Crosshair” functionality instead of the “Slice intersections” functionality?

hi, @jamesobutler

As described in the above figures, we want to get the effect of displaying crosshairs in a single view.

Thanks

@mau_igna_06 Yes, the enlarged view with crosshair is more effective when selecting. @jamesobutler Please add this function if you can.  
thanks

The “Crosshair” functionality already exists when viewing a single view. Below is an image of the red slice view in a temporary maximized state from the four up layout.
