elements visible and selected in the wrong floor.

In our project we have several voids. We founded some problems, when we select all visibles in the view (one specific floor) it also select some of those in the lower floor. How can this be possible?

This happens because, even if those voids are not graphically “visible” (since they are located below the floor), they are still within the view range of the plan.
When you use Select All Visible in View, Revit does not only consider what you can actually see on screen, but all elements that fall inside the view’s cut range.

That’s why voids from the lower level are also being selected: they are part of the view range, even if hidden below the floor.

To avoid this, you can adjust the View Range settings of your floor plan.

That might be a reason but unfortunately it is not here. 

As you can see void A is 25 cm and void B is 37cm. I only select void A, according to the view range I should select both.

I see, thanks for clarifying. If only one of the voids is being selected, then it’s not just the View Range controlling the behavior. A few other things can affect whether a void is included in the selection:

• Host relationship: if a void is cutting a host (wall, floor, etc.), it will behave differently than one that isn’t actually cutting geometry.
• Category/visibility settings: check if the voids belong to different families or categories with different Visibility/Graphics overrides in the view.
• Element level: sometimes the level to which the void is associated influences whether it’s considered part of the view.
• Family cut settings: if one void is inside a family that cuts with voids and the other isn’t, that could explain the difference.

So, even though View Range normally explains this kind of selection, I’d suggest checking those aspects. Very often, the key is whether the void is actively cutting geometry or just “floating” in the model.

But without more information regarding the type of elements and their relation with others it's hard to tell you more.

Hi,

Could be the family has a model / detail line in them in the Z-direction so while the geometry is maybe not in viewrange a part of the family might be (can be a hidden line in family)

So if the family should be out of view (when using select in view) check the family?
