What is this seemingly-extra wall line?

I'm customizing a floor plan Visibility/Graphics setup, and as I'm going I'm making my walls have dashed cut lines. As I go I'm noticing all the walls' edges are comprised of two lines. This wasn't visible until I changed the walls' edges from solid to dashed lines. Does anyone know what the second line is? Obviously one of them, I'm guessing the thicker line (I haven't modified the line weights for walls), is the edge of the wall. But what is the other one? None of the subcategories under walls (Common Edges, Hidden Lines, Cornices and Trim) toggle the visibility of this thinner line, so they evidently are not connected to this line. This is also evident because the thin line's pattern stays the same as the thick line's pattern (if I change Walls to Dash Dot, both the thin and thick lines take on this pattern).

Any ideas? It would be nice to be able to modify this thin line for different View Templates.

Maybe the Analytical Wall?

That's a good thought, I didn't check that before posting. But the "Show analytical model categories in this view" box is unchecked, so that can't be it.

Yeah, it was remote.  

 

Let's take a look at it. Up close and personal. Post it. 

 

...or give us a routine to replicate.

It should be simple to replicate. Just set your visibility Graphics menu the way I did in that image, then zoom in on a wood stud framed wall, particularly its interiorwhere the inside face of the studs touch the gypsum drywall layer. I don't know if it matters if it's cut or uncut, I think the one I posted is a wall being cut by the view range.

@Redrunner92 You've overridden projection lines... So you're looking at a wall going around the corner and if you adjust the view depth of the section it will not show... ? not sure that's the line you're talking about now actually, while writing... let me recheck the image posted :leicht_lächelndes_Gesicht: edit: hmmm, could you add a floorplan to show what the section is looking at? (or the file...)

The image above is of a plan view, not a section view, and the wall is not going around a corner but being looked upon from above. Also, a correction from what I said above: the wall is not being cut by the view (as I should have known, the V/G change I made is only to projection lines, I didn't change the cut lines in the view).

The file should not be necessary, it is simply a wood-stud framed wall with GWB on its interior that is not being cut by the view range, and the V/G is changed to have dashed lines show for all Walls' projection lines.

Update: I tried joining the wall to the floor element below it, and that did not change the line in question. I even deleted the floor element, still no change. I deleted the stem wall below it (though the wall and the stem wall were not contacting each other), no change by that either. I deleted the GWB layer and still no change occurred. So this thin line seems to be present simply because this element is a wall, and not due to specific layers nor to joined geometry nor to V/G settings nor Object Styles.

is there an underlay in the view? can you post a picture of the structure of the wall? or even better, does this happen in a new project with the same wall structure?

Ok here is a simplified version of the file. The wall on the right in the only provided floor plan view is the one I showed in the original image. Zoom in on it and you will see the two lines, one thick and one thin.

 

Yes, there are phases in this project. I'm concerned with phases 3 and 4. This behavior is happening in both phases, even with a different wall type being used in phase 4 when compared to phase 3.

There is no underlay and yes it does happen in a new project with the same wall type.

it might have something to do with your phasing and phase filters. Wall was created in Phase 1 and being demo in Ph4. The view Phase is Phase 3 with the filter as "Show Complete".

You have the top of the wall layer unlocked, under type edit modify (section preview). You could lock it again, or remove the line using Lineweight command (shortcut LW) in any case. edit: hmmm looking at it again, I don't think this is what you meant either. But I don't see any other lines or double lines when opening the file, in Revit 2020.2.1 that is not 2018 (see answer below by @barthbradley perhaps this is the case)...

Do a print preview. If it's what I think it is, it won't show in print preview.

 

I think what you are seeing is related to a fairly common display phenom.  Ever see model elements, such as beams, showing through sheathing in a Hidden Line view?  But when you zoom in, all looks normal?  I think that is what you are seeing. 

 

FWIW: that's all I can replicate at my end.

The printed PDF file (I couldn't zoom in close enough on a print preview) indeed does not show this thin line. So it seems you are correct, this thin line does not show up/exist when printed. I'm still curious what causes it though. I noticed when I deleted the walls connected to the ends of the subject wall, this thin line vanished in Revit. So at some point the thin line was brought into existence when I connected one or more walls to this wall's ends.

I didn't think to connect it to the beam-sheathing occurrence, that was a keen connection you made.

Anyway, it's nice to know the thin line will not show up when printed. Thank you. Do you have more info on this phenomenon, @barthbradley ? You mentioned it sometimes happens when beams intersect sheathing; are there any other instances you have seen this happen?
