cant find the source of error

[Anonymous]

Hi everyone. 

I have a problem with my project file. 

The situation is:

1) I have grouped a whole floor level with it's component.

2) then, when i tried to edit the group, it says 

            'Can't make change to Group "Level 1 a" with more than one instance. To resolve: Ungroup and Group again under a new name. Edit and make change, then change all instances of the original Group to the new Group.'

3) I tried to Ungroup the group, then it says, 'Profile sketch is empty!'

so, i cant find which profile sketch is empty. I really dont know what to do. but i cant afford to do the model all over again.

please, if anyone can help me, i am very2 greatful

Are you doing anything programmatically, or just using the standard Revit user interface?

If you are not doing it programmatically, please note that this discussion forum is dedicated to programming Revit using the Revit API.

Therefore, you cannot expect an answer to a question such as yours relating to installation, product usage or end user support issues here.

You should try one of the non-API Revit product support discussion forums instead for that:

https://forums.autodesk.com/t5/revit-api-forum/this-forum-is-for-revit-api-programming-questions-not...

The people there are much better equipped to answer your question than us programming nerds.

I hope this clarifies.

Thank you for your cooperation and understanding.

Best regards,

Jeremy
