Floor plan - simple view range issue

[Anonymous]

I am the beginner who cannot solve what seems to be very simple view range issue.

So I have two walls that reach level 1 and one wall which goes through it up to level 2.

When I set cut plane to zero, on floor plan level 1, I see only one of walls that reach level 1, and don't see at all wall that extends to level 2. I cannot find any logic in that.

Sorry, but that simply doesn't help, I saw that explanatory image in Revit help, but that in no way helps my specific problem.

So why one wall is visible and the other is not if both are of the same height, why wall which protrudes to the next level is not visible at all?

If it is not the solution, it is better to not mark it as a solution.

Could you add a picture or maybe the file itself to figure out what is going wrong?

Completely agree, sorry, either I cannot find how to undo "accept solution" button, or it's not possible, anyhow I see it's not good idea to try to post here via smartphone.

Here are the images.

On first screen you can see how it looks like on floor plan and what are the view range settings.

On second screen all three walls are highlighted to make their heights understandable. W

What I am looking is level 1 floor plan, where I believe all three walls should be visible, not just one.

I think Revit shows it correctly. The walls are exactly till level 1 but are related to level 0. Cutting them where they stop should not make them visible. It does make sense what Revit thinks.

If you want to see the walls of the layer below, adjust the view depth and/or the bottom plane just a little bit lower (-50). Or use level 0 as an underlayer for level 1.

I don't understand the issue.  Your screenshot clearly shows  that all your view ranges are all set to zero.  Based on those View Range settings, there's no walls to see, except the Underlay.  Turn off the Underlay and the View will show nothing at all.  However, there are families that with show up in with those settings.  For instance, if you had Casework or Windows whose model geometry was visible "When Cut In Plan/RCP" (per family Visibility Settings), then those would show up if they were within the Primary View Range.  

This information and short video may better explain what's going on:

Avaris, how can it be correct if one wall is visible, and the other is not, despite the fact that both are of the same height?

Barthbradley, to the best of my (rookie) understanding, offsets are set to zero, not view range. My view range has level 1 as bottom level, level 2 as top level, so comprises the whole floor height. When I change cut level offset to any value, than 3rd wall (that one which extend all the way up to level 2) show up.

Sorry @Anonymous: I'm not following your logic.  Perhaps I'm misunderstanding what you are trying to do.  Are you not wanting to display any walls in the view?  What's the purpose of the view?  Maybe, if you tell me that, I can advise you on how to get there.  Maybe, VG overrides are the means to the end, instead of View Range.  

...btw: did you check out the video I linked you to in my previous post? If not, I would encourage you to do so. It talks about what families can display above the cut plane of the view.  Walls are not one of them.  Now, if you were to draw your walls as an in-place Generic Model component, they would show up with those settings you have.  

The following component family categories will appear in the view even when above the cut plane:

-Casework
-Generic Model
-Structural Columns
-Windows

[Avaris.]

I think they are both not visible, only the wall going towards the second level is showing up. You might have scrambled the names of your views. Hard to tell without an actual file.

Thank's for patience.

What I am trying to do is what I do often when learning new things, and most of time that brings faster learning - I am trying to provoke different scenarios to understand how things are doing rather than learning event by event by "mechanical" memorising.

This looked as some simple problem to me, but now appears that is is not. I will try to reprhase it to the best simplicity I got.

- Right wall on the image extends from level zero to level two. I the cut plane is set at level 1, without offset, how could cut plane "miss" this wall? No matter which offset I set for cut plane, it will always be somewhere in the wall. So why this wall is not visible.

- The other two walls have exactly the same height, 4000 mm. I set cut plane to level 1, without offset, which is exactly on 4000 mm height. So why one of these walls is visible, while the other is not?

[Avaris.]

Well, as said previously, I think the walls of 4000mm are not visible, but the wall going to the second level is visible. Could you please add the file for further troubleshooting?

[barthbradley]

The only wall I see visible in your view, is the one coming from the underlay. Set Underlay to "None", and no walls will show.

I checked that number of time to make sure that I am not referring to wrong wall. All are with very different length, so confusion is not an issue, I believe.

The file can be sent, of course, but as I added many new awkward elements in the meantime, I'm not sure can it be readable. 

[Avaris.]

Just upload it, I'm sure we can figure it out. You can first try @barthbradley suggestion.

[Anonymous]

Ok, here it is, just hide that fancy roof so you can see the walls as described.

Confusion must be the issue here, because I looked at several  Floor Plan views in your file and they all display correctly and in accordance with the View Range Settings.  I think you need to let go of your logic and learn Revit's  logic.  Here's another article I found for you. Perhaps it will provide you with that "Aha" moment.

If you examine the way your views started out, in the stock template(s) you'll find the cut plane for plan views are assigned to 1200 mm (metric templates). That's because it is necessary for the cut plane of the view to travel through the element (varies for different categories as mentioned earlier) to see it. Further the Top/Bottom settings for the range must be offset by a non zero amount from the cut plane value/position for the graphics to be drawn in the view.

When you set all of the values to zero only a wall that ends at exactly that location will be visible, horizontal wall at the top of the view. The view needs some height in order to display the walls.

It seems consistent with what I see, and now after reading complete text of @barthbradley links, I also found that elements above cut plane and below top view plane are not visible in floor plan (with 3 category exceptions, but wall is not one of them).

Thanks much, people, for the efforts. I am trying to accelerate my learning curve by inciting complications rather than sticking to "middle of the road" paths, and that is tedious sometimes.
