View Range

[dm0144]

Hello everyone 

Any clue why the slab above the foundation is not visible in foundation plan (-3) with the current view range settings? The desired outcome is plan of the foundation piles and the outline/footprint of the slabs above.

Because it is above the cut plane...Give the cut plane 200mm offset to cut through the slab and use show hidden lines 

Edit: see GIF below

@RDAOU Than, I have to change the visual style to Wirefreame in order to see the piles bellow the slab and override the cut pattern with white color in order to get just the outline of the slab. This is the only way?

@dm0144 

The slab will be hiding the elements below, you need to Use Show hidden lines...Alternatively

• cut below the slab >>>
• set an underlay to look up and
• use Linework to mark the slab above

@RDAOU Isn't that the point of the Top Plane in View Range, when compared to Underlay, to display elements above the cut plane?

@dm0144 

The behavior is determined by the Category of the element you are using and what applies to some categories do not apply to all...in other words not all elements show when above the cut plane...Example: Generic models does, Slabs don't.

@RDAOU hi

The main issue I have is that I can not spot elevate the slab. Is it somehow possible particularly the underside of the slab?

@dm0144 

I'm afraid I don't understand the question and how it relates to view range. Can you please elaborate on what you are doing exactly

[dm0144]

Refering to the screenshot from my question, I am doing a plan view of the pylons at level -3 Temelji. Together with the pylons I also want to show the outer boundary of the slab above, which is not visible at that level. When displaying the outer boundary of the slab, I would also want to display spot elevation of the bottom side of the slab (at what height is the bottom side of the slab using spot elevation). 

How can I display the height elevation of the bottom side of the slab which is not visible at -3 Temelji.

Activating an underlay showing the Level above that is hosting the slab will allow you to elevation tag the underside of the slab. See the settings in the screen capture and floor plan below

Hope this helps,

In such cases you usually tag the pile caps and not the bottom of the slab (The pile caps are technically at the bottom of the slab) See GIF below

[dm0144]

@RDAOU and if there are no piles? Is tere a solution to spot elevate the bottom of the slab?

[RDAOU · Accepted solution]

@dm0144 

Either while placing the spot elevation or when selecting an existing one >>> from the drop down menu use Bottom Elevation or both Top and Bottom (See GIF below)

The problem as I see it is this: You wants to be able to tag the underside of a floor slab on a plan view which is on a level below the hosted level of the slab and Revit won't allow you to display it.

In my experience, this is usually resolved by having the information on two seperate drawings, which Revit handles without a problem.

1. A foundation and pile plan showing the location of piles and levels top and bottom as required. The outline of the slab is a plus but not always required;
2. A slab on grade plan which can show the top and bottom levels of slabs, from which excavation information can be extrapolated.

But I understand you want both in the same view and since in Revit, if you can't view it, you can't tag it, the problem is how to display cut foundations and the slab above in the same view.

Solution 1: Use underlay to display the slab in the foundation level view.

Solution 2: Create a view level called "Piles" on the slab level called "Slab". Change the visibility graphics to show the slab with hidden lines and the piles with thick cut lines.
