Slab visibility quirks

[kate.morrical61357]

I'm using shape handles to control slopes & ramps in a parking deck. It seems that as soon as a shape handle gets into the view range of the level above, the *entire* lower slab shows up (as hidden lines if there's a slab on the upper floor, as solid if not). Ideally, I'd only like to see the half of the ramp that's in the view range.

I was avoiding slope arrows, since I need to have multiple slopes in the same ramp, but I may have to go back to that if this is supposed to be this way.

Is this a "feature", or have I found myself a bug?

This appears to be a problem for non-sloping slabs as well. I have an elevator pit slab that's 4' below my typical floor, and even when I adjust the view range to be cut off 1' or 2' below the level, the slab still shows up. It's messing with my wall display. Grr.

What level do you have it associted with? A seperate level or the one you are trying to look at? I have no idea if it makes a difference, but when you offset the slab I think RS sometimes thinks you still want it associated with that view and not the level below. If you are having major issues the Adesk workaround will either be to use the "Hide object in view" tool or the line work tool. Or at least that's the generally the response I get.

I just found this on the RA forum; somebody else with the same problem got this response from the factory:

Unfortunately, this is a known issue with Revit Architecture. Floor slabs are objects that will be visibly if they are 4’ below the level that is being shown. The workaround to the problem is to use the Override graphics in view, to make the slab not visible in that view. To do this right click on the floor slab in the view where you do not want it to be visible and select Override Graphics in View -> By element and then uncheck the box for Visible and click OK.

No idea why slabs/floors are exempt from the view range...seems kinda silly.

I'll give them props for the workaround. That's better than most responses.

But is turning off visibilty with Override Graphics any different from Hide In View?

[david_peterson]

It should be since you shouldn't be able to select only the slab if it's a link model. Now if you inserted it, then it's a part of Your model and you would be able to. Think of it like an xref. If you hide the object in view (the xref) you turn everything off. If you go into the layer dialog and freeze just the slab layer, you're only turning that off, not the whole x-ref. In a struct model I'd think the only thing you may want to see is the cladding, stairs and elevator shafts. Interior partitions, I would think you'd never want to see. I guess it depends on what you're trying to show.
But to answer the question, yes there's a difference.

[kate.morrical61357]

Ah, okay. So if it's a linked model and I "hide object", the whole thing goes away, but if I "override graphics", only the slab goes away?

Kind of a moot point, though, since it's my slab, not linked, so the effect is the same.

[david_peterson]

Yep, you've got it. Hope this helps.
