Bottom view range showing more than it should

[Anonymous]

I have two problems here –

Firstly I am finding that when I set a bottom view depth, Revit will actually show slabs that are close to (but not actually included) in that view range. So if I set the view range to 1800mm below level 2, if I have a slab that is 2200mm below level 2, I will actually see that slab even though it is not actually within the view range I set.

Secondly the same applies when I have a ramp from the level below my current view, travelling up to the level of my current view. Instead of the bottom view range cutting the ramp part way down the ramp (which correctly happens if the ramp is travelling past my top view range going up to the level above) the whole ramp from the floor below is shown, which means my linework does not look right as I have dotted lines underneath my slab (IE: showing the base of the ramp on the floor below).

hi

that would be hard to solve without seeing the actual model, but first things I would check are the underlay settings of the floor plan, the far clipping settings, and what is the host level of the slabs and ramps

Hello,

Floors in Revit follow a specific rule where they still show as long as they are within 4’-0” of the bottom view range:

Ramps are similar where they do have special behavior in terms of view range.  This is a good link with general rules for view range:

I hope some of this information is helpful, please let us know!

Thanks,

Thanks Ryan. Do you know why there is the 4'-0" allowance? Obviously if a user sets the view depth to a certain level its because they need it to go down to this level, without seeing items below it no matter how close they are.

Its been hard-coded this way pretty much forever, mostly to allow floors to display generally for cases where there may be slight level changes (maybe a foot or two) that may otherwise not be included in the view range.

Yeah. Great. And I wanted to grab pc case and jump with it out of a freaking window because it got me frustrated for 1,5 days...

P.S. Autodesk, please, start some major 5-yr projects of rewriting software cores - I believe in case of Revit it would mean writing a whole new software, because it's so bloated ;/... and because the profit from that process would be abysmal all coders in your company who come up with that idea are fired on a spot... ;(
