Re: I still Can’t understand View Ranges

03-07-2012 01:33 AM in reply to: Alfredo_Medina

Thanks

 

That clarifies what's happening, but I'm still not sure why. As I said in my previous post, if the Bottom & VD are set to -500 the slab *still* shows. From all the web pages/help files I've read this shouldn't be happening.

 

Are there any other settings that cause the View Range to have different characteristics?

Cheers

There is, indeed, something very strange about those view range settings, maybe a bug which seems to affect only slabs. If I place a structural column and a structural wall with their top set at the same height of the top of the slab, the column and the wall are hidden by those view range settings, as expected, but the slab still shows.

This is not a bug, it is expected behavior.  Floors have a slightly different behavior with respect to view range.  That is what you are seeing here.  A floor object outside of the primary view range is still displayed if it is within 4' (or approx 1.22m) of the bottom of the view range.  Quoted from the wikihelp topic on view range:

 

" Model elements located outside of the view range generally are not shown in the view. The exceptions are floors, stairs, ramps, and components that stay or are mounted on the floor (like furniture). These are shown even when slightly below the view range.

 

Fascia, gutters, and slab edges are shown when their bottoms are within a tolerance of the primary view range bottom.

 

Floors located outside the view range use an adjusted range that is 4 feet (approximately 1.22 meters) below the bottom of the primary range. Floors are drawn with the Beyond line style if the floor exists within this adjusted range. "

 

I think this explains what you are seeing with this condition.

 

You can review the topic on view range at the wiki help for further information.

Ahh, excellent, Jeff. That was the reason for this display issue. Thanks!
