About the Draw Order of Details
Details always appear on top of model geometry. However, you can change the draw order of details, placing them behind or in front of other details.
Show Hidden Lines
Use the Show Hidden Lines tool to display model elements and detail elements that are obscured by other elements in the active view only.
Remove Hidden Lines
After using the Show Hidden Lines tool to display lines of model elements and detail elements that are obscured by other elements, you can use Remove Hidden Lines to reverse that setting.
