Revit 2018 can't copy simple model group

[gustavomello]

Hello, I'm using Revit 2018.1 for the first time in a project. I have a simple group which have only walls.

The spaces you see are for the structure that will be linked at some point. The problem is when i try to copy the group Revit wants to "fix" it because it would have different elements.

And it seems that the problem is that Revit  creates new types for some of the walls because they already exists in the project (like when we copy from one project to another, which is not the case) causing the issue above. Warnings 2 to 5 are like this:

The walls in the group use a global parameter in the top offset. I've tried to remove these and the problem persists. I've also tried to remove the walls of the types described in the warning from the group but got no luck.

Does anybody have a idea of what's wrong?

Thanks,

Gustavo

Solved! Ungrouped, deleted the group definition and grouped the walls again. But if someone have an clue on what hapenned I would like to know.

This error will appear when you create or ever created a new Wall Type during the Edit Group mode for the Group you would like to duplicate. For some reason Revit 2018 don't like this.

Thank you Loekvsteijn. So we are back to the time when we had to create new types outside group definition to add them later. Sad! I hope this can be fixed by Autodesk.

We have just had a similar issue with ceilings that were in a group.  75 ceiling types in the project now, cool. 

Glad to see we aren't alone!
