I am working on project were it is required that all structural floors with same thickness have same color and be in same group such that we can select them all together with the same click. Also, I need to export the file to autocad and maintain the same group function.
I was able to group them in dynamo and assign colors to those with same thickness. but could not group them in revit.
I don’t think that node is set up to work with lists of lists at this time, which means you may have to play with list levels/lacing or update the code. Note that if any of your elements are already in a group you also will not be able to add them into a new group - this would result in you modifying a group outside of a group, which is a no go.
