Bug? - mutual position of walls is messed after copy

In the attached image you can see two enclosures that are a small part of a bigger project.

The lower one is correct. I can move walls and doors with no problems, but when I select them all and copy anywhere in any possible way, their mutual position gets messed (randomized?) and the result is like the upper enclosure.

If you look closely, you'll see the walls got split in sort of two groups - with correct mutual positions inside each group, but the two groups are offset to each other. Two outer walls are in one group, and the rest is in the other.

The issue only occurs with these very walls in Revit 2016.

Copying to a new model doesn't help.

Does anyone know how to fix that and does the issue even occur in newer versions of Revit? I can't check myself.

I am not sure what has happened here but i can repeat the error.  I tried all methods of Copying/Grouping /Assemblies/Etc. and nothing worked i can only put it down to very small misalignments.

 

The only solution was to select each Wall > Edit In-Place > You get a warning about inaccuracies > Green Tick to Finish (without doing a thing)

 

One this is done to all the walls it can be copied without issue.

Have you try to recreate the in-place family? When I recreate in-place family that cause the issue, it seems to stay in place. I assume it could be older Revit file having issue when you upgrade.

As well, there is no warning sign reporting for the older in-place family. When I recreate the in-place family, it shows the warning sign. I would recreate the family or this will cause corruption in the future.

Model in place then multiplied using copies of group?  I would not do that.  The error you have is one thing but not the main reason. The main reason is that you are going to have multiple in place models and when you need to revise, you have to do it one by one, or delete all copies and recopy again.

 

Model using basic walls, you can stack multiple walls to create a thicker wall then join them, for odds and ends, use an architectural column family with instance parameters (stretchable) to form them.  Then you can create a model group and copy it.

Jay_colcombe, as you said, "refreshing" all walls by Edit In-Place fixed the problem, although it's a little time-consuming. Luckily, I only had a few degenerate walls, but I don't know what I would do if the same issue occured with like a hundred walls. I guess I'd have to make a script for that.


Syman2000, the issue is not related to model upgrade. The walls behave just the same in Revit 2016 and when I open the model in Revit 2023.


ToanDN, the walls are not actually grouped, speaking in Revit terms. I just commonly used the term "group" to describe two sets of walls, regardless of Revit hierarchy. Also, I can't use basic walls because I am working on a point cloud and have to respect every tiniest deviation of wall's thickness.
