Why vertically stacked walls with the same finish have line between them?

[Prvoime]

Here is an example of two walls, same finish, same thickness, one on top of the other, but there's a line where one stops and the other continues. Join command doesn't work.

I can easily get rid of it with linework to invisible, but I'd like to know why is it that sometimes when I create two types of wall with the same finish, stack them one on top another and they join just fine, and other times they behave like they have completely different finishes and refuse to join?

Attached example of misbehaving walls.

They are not the same materials.  The walls have a reverse orientation from each other.  

...Yah, @Prvoime: something else is going on here besides the fact that your walls are facing different directions (e.g. Exterior Side is aligned to Interior Side). The only way I found to fully correct it is by Merging/Removing the Split Sections and following the prompts to correct the Wall Assembly.

Edit: Join geometry only clears the line if a section box is on and cutting the walls.

Join Geometry.

Even when I flip the lower one (which is interior wall, and orientation doesn't matter to it) it's still the same. Or create a new one by dragging it in the "opposite" direction.

Yeah, seems like split region is causing this one, when removed, joining works fine. So linework it is.

What was strange to me, was that I could leave the Split Region as is and just correct the Exterior/Interior Materials - and then Clipboard Copy and Paste the whole enchilada into another Project and Voila! No Line.   

c’est la vie

- Get rid of Split Regions and Add Sweeps for base

- Join Geometry

- Drag one wall end to be longer or shorter, then drag it back to align, and the walls will join without any line

- result:

Can't, it's not an actual base as in wood profile of some sort. The entire wall is plastered, but the "base" is the part of the wall that is covered by finish floor layers i.e. it's not painted.

Plastered wall height is 290cm, after finish floor is installed painted height of that same wall is 270cm (example).

I found this to be the simplest way to get the correct plaster and paint quantities.

Anyway, it's a rare oddity, or Revit bug, I'll just hide it with linework in this one place where it shows up.

Shouldn't the floor goes to meet the wall core and the plaster stops above it?

You could also get the same result with a stacked wall and you no longer need to deal with the line on elevation manually.  

Anyway, sweeps are not necessarily for wall base or wainscot.  In this configuration they serve the same as a layer of plaster finish as the splitted regions.

Considered them, but where ever I read anything about stacked walls it's always "here's how to use them, but, use as a last resort, avoid if possible, abandoned feature...". So without knowing how wise is to use them, I decided to skip them. If anyone has some firsthand real world experience with them, I'd love to hear it. Pros and cons?

Not really, well, maybe, but no, maybe yes, but more complicated, so no.

With split region I get everything in one material takeoff. Wall paint 130m2, plaster 134m2. Done.

But If I add them as a sweep in wall assembly then they aren't listed anywhere in material takeoff. Anywhere, not even in sweeps schedule.

So I'd have to add them manually one by one through wall - sweeps command, and then get their lengths, and then calculate areas.
