Wall Wrap at Inserts

[dm0144]

Hello everyone

Sometimes, the exterior layer of the wall won't wrap around window or door in this particular situation like in the picture bellow. The cross hatch elements are walls, joined with the long one, which is the host of the door and window.

Any clue and fixes?

Wall wrapping is controlled in the wall settings, but also in the window/door family type used. So check the window/door type's default wrapping setting, because this could be set not to wrap. If set to byhost, it should follow the wall wrapping settings...

[dm0144]

All types are have closure setting as "By host". Still somewhere the wall wont wrap.

I am attaching revit file with the particular example.

The construction of the window family was the problem. Editing it in the family editor solved the wrapping problem.

See your file attached.

There seems to be nothing wrong with your model. Exterior layer wraps fine at inserts (Below is a screenshot of your model opened as is without modifications)... Which Revit 2021 build are you using? it might be some bug which got patched with a hotfix 

@ahjorn whatever you did to that family was not good 🙂 using the model you uploaded, place a section through an insert you'll see what I mean

[ahjorn]

@RDAOU Yes you're right, thanks.

I deleted the wall opening from the family and replaced it with a void. Just a habit that I have.

@ahjorn 

Nothing wrong with voids...just in this case you need to keep it locked to the faces of the wall NOT the reference plan. If locked to that reference plane it wont cut the joined elements/walls (the reference plane you locked it to labeled wall depth which can be misleading - it should be labeled Window Inset)

[dm0144]

@RDAOU Most of the time works fine, but at some places it won't wrap. Please check the marked window. If I I move it slightly or change it's size slightly, the exterior layer wraps but, at this point it doesn't.

[RDAOU]

@dm0144 

That is not because of the window...it is because of the join order...switch join order of the wall and it will wrap fine

[dm0144]

@RDAOU That way, the model will not be structurally correct since, the shorter wall elements within the wall are reinforced concrete, which is continuous and it should fill that volume, instead of the blocks in the wall, which are not structural. The concrete blocks are only between the RC walls(pillars). 

btw, is there a reason why on the right side of the window, the exterior layer extends slightly behind the layer beneath it. It clips through.

[RDAOU]

@dm0144 

Switching join order does not effect the structural integrity of the walls...NOTE: I did not ask you to swap the interior wall with the exterior wall...ONLY switch join order (the reinforced concrete will stay reinforced concrete and the block will stay block) 

Alternatively...Unjoin Geometry...Then Start Join Geometry >>> Check Multiple box >> Select Outer Wall first then select the inner walls 

Edit: The layer is not extending, they are simply overlapping ...Repeat the Join Command ... Select Exterior wall on the right then select the interior wall perpendicular to it. 

[dm0144]

@RDAOU when the join order is switched, you can see in section that the reinforced concrete is discontinuous and there is the nonstructural blocks in that place.

[dm0144]

@RDAOU is there a way to fix it with the current join order?

[RDAOU]

@dm0144 

I see what you mean.

I don't have access to a workstation with Revit atm... In plan view, can you try to either nudge the window left or right OR grab the end of the interior concrete wall (say the one to the left) ...if it cuts and wraps properly then your issue would be

1. either in the inconsistency of wall joins / layer functions 
2. or in the constraints of the opening

[dm0144]

@RDAOU if I move the window slightly or shorten the concrete wall the layer will wrap properly.

What does it mean inconsistency of the wall join/layer function?

[RDAOU · Accepted solution]

@dm0144 

Sorry for the late reply I was out all day...Inconsistent joins means you have so many either random or simply various types of joins for several walls at one location (in your case at that right hand corner 4 walls). When there are too many of them, Revit might find it difficult to interpret the desired connection you are after.

Sometimes that just happens and needs a little bit of patience to revisit and fix joins here and there... See GIF below for the Fix

1. Temporarily isolated each 2 interior walls,
2. allowed connection
3. Dragged ends or use Wall Joins to achieve desired connection/join  (Butt or Mitter)
4. Reset Temporary isolate
5. Selected the 2 exterior wall and temporary isolate
6. Disallow Join and drag ends to fillet
7. Join Geometry 
8. Allow Join again to invoke  Layer Function priority join
9. Drag to adjust or to achieve desired connection/Join

Now your walls are properly joined and properly wrapped at insert

Note: there is a constraint issue in the window family which you have but it is not major you can ignore

@RDAOU Thanks!
