Almighty Stairs Won't dissapear from view

[Anonymous]

I have stairs going from a Basement to Level 1. In the level 1 plan, the stairs refuse to be masked by the detail item; filled region or masking tool, or floor. Also see in the screenshot the view range is not set to below level 1, year I can see the whole staircase all the way to the basement. 

How can I control this disobedient object?

Change Underlay to None.

Set underlay to none. stairs in basement still visible.

Are you sure the floor in the room above the end part of stairs is actually there and not transparent?

This is typical behavior. Use a Plan Region on stairs.

While this is a new tool for me, and I def understand it and like it, it did not fix the problem. I set the plan region to 0' in all categories, and it did not solve the issue. I am not showing floor plans in this view. I believe I will have to do that, and switch all my floor types to appear as plain white in coarse scale for this view. We originally did not want to see floor finishes in these building floor plans.

You should keep the floors category visible, but turn off the surface pattern from VG, to cover things underneath the floors just like this stair.

I'm not understanding. You are on Level 1 and Stairs from the Level below are visible in the View, and you don't want them to be; right?   Plan Region will work.  You just need to get the Stairs out of the View Range by more than 4 ft.  Zero will not work.  Also Plan Region boundary cannot be in contact with the Stairs.  And, View Range Levels must be set to named Levels. 

...Here; this explains behavior. Read about exceptions under "Elements Below the Bottom Clip Plane and Within the View Depth":

Can you check whether the plan is in "Wireframe" mode??

wireframe

Cause if its in wireframe then floor or masking , nothing is gonna work..

[Corsten.Au]

wireframe..

yeah the view region exceptions are annoying, not only for stairs.

Another way is to use masking region or use linework tool and set it to invisible. Tedious, but at least it works for other situations when you cannot use mask or plan region.
