Riceve messange "One or more dimension references are or have become invalid."

it happens. You've got a dimension in one of your views that is pulled from the very spot you're trying to modify.  By making the modification, you are removing that reference the dimension is pulled from.

It's okay to accept deletion of the dimension.

This dimension?

Someone can say me there si a way to Highlight all dimension in file?

How can I understand what dimension is?

These in attachment are in roofperimeter but not visible if a don't edit schetck

you don't have any dimensions and you don't have any warnings in the project. What's the problem?

Tghe problem is understand when have this signal and for what. 

In my second attachment say that there is a problem with dimension id 202254.

If click on command "id select" and put this code there no underlight dimensions because dimensions is in scheckt and not visible in project if I not click on edir the roof. 

Now haven't a problem, but try to understand how revit works and if I can resolve problem to myself if have this kind of notice.

Thank's for answer.

the only way you could have made the roof modification and exited out of edit roof sketch mode is by letting Revit delete this dimension. It no longer exists in the project you posted for us to look at.  How can we help you figure out the problem, when there is no problem.  If you are determined to find out what that one dimension was, may I suggest that you either: 1) undo everything you did, or 2) open a backup file and search by element ID #202254.

Did you enter any dimension when you sketched the original roof?  If so, when you edited the sketch to add slope arrows and whatnots, the dimension became obsolete so it needed to be deleted.  It's similar to the scenario when you dimension a window mullion to the floor, then you change the window to a different type without any mullion, and the dimension got deleted.

So, it maybe good trying to find out what the warnings are about.  But it is even more important to set your priority straight, and accept that something can and should be ignored, especially when you enter the production environment.

The importance in this case is to remind to open the sketch because when is signal the warning you are not in edit sketch and it happends you try to search in normal view that there aren't.

@barthbradley sorry maybe in the project attached have previously delete dimension understand is there the problem. 

Even if do not understand why say so, the warning show up when put skow arrow, but don't chang the dimension od line quotate.
