Revit sees changes in one group when I try to change a different one

[LOESCH_PK]

Hello everyone

I'm making a project of a hotel and Revit is making a very strange problem which paralyzes my work. As any hotel this one has multiple coppied and/or mirrored rooms. The problem is, that once I have an array of rooms next the each the moment when i want to delete or change one room (a group of elements) an error accoures that says that I can't modify a subelement of a group. The funny thing is, that it's always the doors in the group next to it that in no way is moved by the fact of changing the first group. The funny thing is that when i delete a pair of rooms the error doesn't always happen. I tried ungrouping, mirroring the room, and grouping again under a different name, but  the problem still hapens. Deleting the walls and problematic doors and recreating also doesn't help. sometimes I can't even delete the doors in one group, because it also says i modified the ones in a different (but simillair) group next to it. I attached a file with three room types. The problem happens when you try to change the middle or the upper or lower room to a different type.

Oh, and some months ago I did simmilair things on the same file I'm working now, with grouping rooms and changeing them and there was no such problem.

Big thanks for any help!

Please show us the steps you are making on the attached sample by doing a short screencast (alternative). Hopefully it shows all messages or situations  you mentioned. I want to reproduce it on my computer exactly as you are doing it.

Thank you for your reply Claus. Simply open the file, pick the grouped room in the middle, and change it to a different group in the proporties pallete (there are 3 groups in the file). If I have more time I'll make a screencast, but I think the problem I'm having is pretty easy to reproduce In the file I attached.

Hi!
I don't find trouble too.
Firstly I separated rooms, and after this changed some group types but only got some warnings about balusters.., you probably mean something bigger.

Hello Semko,

Thank you for your reply, but you missed the point a bit. The "rooms without boundries" or "two rooms in one space" is not the issue here. The problem is that the groups behave irrational sometimes when I change some of them. The error also doesn't accure sometimes when I change the groups in a specific order, but the project I'm working on has about 600 hotel rooms, so when the error accures ina random moment in a large group of rooms it's hard to work out. I've added a screencast. The error says "changes in groups can only be done in the group editor". Note that the error highlites a door in a different group than the changed one.

The problem does not happen when I delete all the doors in all the groups, but I'll have to add them at some point anyway.

As you can see in my video i did the same thing as you, but without that error.
So, it can be something in your program. Do you use any add-ins or something else. Which revit bild do you use?

[LOESCH_PK]

Well I have to disagree. When I start changeing the groups from top to bottom (like you in your video) the error doesn't happen. Try this: Open up the file, and FIRST thing you do is select the group in the middle, and try to change it. If exactly then the problem doesn't happen I guess it something with the add-ins.

But now I think you might be right with the add-ins. I have an addon that adds an instance parameter to all doors that is a text field indicating the flip of the door (left or right). The mirroring of the groups might cause that paremeter to be different for doors that should be the same, but have it changed do to the flipping. But then again I think I tried to make mirrored groups seperatley  and still a simillair problem accured.

Semko, you have my thanks. 

The problem was caused by an add-on M&P Revit tools, that added a shared, instance "Door Swing" parameter. The add on tried to give a different parameter to doors in mirrored groups. The work aroud is to delete the inserted parameter, and use the addon to add the information only when it's needed.

Big thanks again!

I wonder if it is possible with that add-inn to choose between options for the shared parameter: 'Values are aligned per group type' and 'Values can vary by group instance'. It might solve the issue.

[LOESCH_PK]

Well, the parameter does show up in the project global parameters and has to option to change to  'Values can vary by group instance', so I guess it's worth a try. Thanks for the idea!
