Roof joins not displaying correctly in some places

[Laura_POLO]

The roof joins perfectly when there is no sloping, but when you add sloping all of the sudden the joins turn white in some places, but not everywhere... Why does this happen?

I assume that it is because of the proximity (to the lowest point), but this bug should be fixable for Autodesk right?

Extra info: shaft on the left is the lowest point gathering the rainwater, on the right is the elevator shaft.

 What did you set for the layer functions... substrate/finish etc. ? Possibly switch join order.

Is it possible to share just the walls and roof as a file?

I was unable to replicate this at my end.

Thanks for sharing.

Cheers, K

Attached to this you can find the file.

@martijn_pater you can check the file for the layer functions, but the current situation is the only one that makes everything join perfectly (when the roof is not sloped yet).

@Laura_POLOYou need to change the layer POLO_hellingsbeton - licht isolerend - schuimbeton - 600-750_MTO to move within the core boundary of your floor assembly instead of  along with POLO_dampscherm - gewapend bitumen - klasse E3 verlijmd_MTO and then adjust the layer functions to join correctly... that should do it...

[Laura_POLO]

Changing the layer with hellingsbeton does nothing for the joins.

As stated in the 2 images, without the sloped roof there is no problem for the joins. There is only a problem when the roof is sloped, and closest to the lowest point. The joins further away from the lowest point are exactly the same and have no problems.

So to me this sounds like a bug that Autodesk needs to fix.

Try rejoining the geometry one by one, it does seem to break at a particular point when joining the second wall it probably has to do with the precision of the slope points? Else maybe try breaking the floor into seperate sloping floors...

Adjust floor assembly layers

Did you get it to work? If not, I split the sloped floor into pieces and joined them seperately. I might have inadvertently deleted something though, but using this method it seems to work anyway. It messes things up with multiple sloping directions it seems, but at the moment I can't remember if you had those and/or if I might have edited those aswell... ? Have a look anyway, hope it helps.

Third time's the charm (I hope)... Just had another look at it for you, so I did edit those points before, sorry didn't notice that. I do think it should work like you wanted to do it really, from an end-user point of view, so I would consider it somewhat buggy also. Anyway Revit seems to have an issue with the multi- or twodirectional sloping when joining these walls. It does work though when you triangulate the surfaces (you can overwrite the linework to hide some with LW in plan ie.) and create the slopes slightly different. Have a look at the attached...

Splitting the roof or walls is not an option for us (company).

Like you, I was messing with the points of the roof a little bit more, and when I place only 1 low point in the middle of the shaft (green) instead of 4 on the corners (blue) then the joins are also good...

So I guess that would be the way with the least amount of work.

I'm going to continue building my file and see if this applies to all the situations/shafts and keep this thread updated if something changes...

I'm working on a file/method for my office that has a solution for all the joins of the roofedges aka 'dakranden' in dutch.
