Section Box Snapping to levels mid of the levels may be more of a property for it because I have faced this issue where I want a particular floor and I keep dragging the arrows and can't get the right view.
@jazzsharma200 in 3d we are able to make a section box based off of levels already. By using the dropdown on the view cube we can make the 3d cut exactly where we want by using the tool orient to a view. https://knowledge.autodesk.com/support/revit/learn-explore/caas/CloudHelp/cloudhelp/2019/ENU/Revit-D...
