Hi All I come across this problem in many workflows. In a revit documents there are multiple instances of a group. If want to change anything inside a group, it doesn’t allow it giving a warning that Changes in the elements inside a group are allowed only in group edit mode. Is there a work around this problem?

@Ewan_Opie thanks for getting it started… Man that was painful… The problem as you know is the naming, you have to make the unique groups, swap them to that, make the changes, swap them to a single new group, delete the original group, create a new group with the old group name and dump them back on there… I’m sure someone can clean it up using functions. It’s like that game… [image] This works for me, hopefully it works for you… Cheers, Mark Duplicate and Change Parameter in Group-3.dyn (105.3 KB) [Capture] [image]

[image] Edit groups Revit Hello dynamo gurus, I have a graph that modify railing paths in groups, currently only railings with one segment. [c1] [c2] The problem (behaviour) that we are facing is that the elements of the group within the group instance that we use through dynamo to apply changes are highlighted as excluded. The other problem is that once I run the script the next time I try to run it I Revit doesnt let me do it, see capture 1. [Capture%20second%20run] Another problem is that we cannot create a n…

Hello there, They only workflow/workaround is to rename every instance with a different name, make the change and then replace groups, this sound horrible but it seems to be the only waly as the Revit api do not let edit group, make changes and close.

Hi. Thanks for updates. At least there is some way. Could you suggest some nodes for renaming / replacing model groups. [image]

Hi. Some of the custom nodes are showing error. Do I need to download some package for them? [16-10-2018%201438] [16-10-2018%201439] [16-10-2018%201440]

Hey, Yes those are in Clockwork, the erase one is from Steam, but there are similar in Archi-lab etc. Cheers, Mark

Hey Mark! Thank you very much for this def, I will give it a go and will let you know how it goes, Many thanks for sharing

Hello Mark, I have the same problem abhijeetraje has I have downloaded the last Clockwork package for dynamo 1.x and these two nodes arent there, which version of the Clockwork package are you using? would you mind to share these nodes please?

Hey, Sorry it turns out that have very old packages on my PC! If you use Count at L2 you should be good to go! Apologies, Mark

Hello Mark, Thank you very much the definition works perfectly!!! Thank you very much for sharing!!!

Hi BIMadmin Can you share exactly what packages you installed to make it work? I am thinking of an alternate workflow like this: Select all the instances of model group. Identify and record their insertion point, orientation and flipped state (whether mirrored). Delete all but one instance. Make changes to that instance which dynamo allows if there is only one instance. Insert the group based on the insertion point, orientation and flipped state (whether mirrored). Would like to have your and Mark’s thought on this. [image]
