Difficulties can arise when trying to merge files with different stories. In the following example, two IFC files are to be merged - architectural (left) and mechanical (right). The mechanical IFC file has had stories broken down further, causing a mismatch.
From this window, there is no way to add in the extra stories on the left. The only workaround currently is to close this, and modify the architectural file beforehand manually to match the structure. It is also challenging to do that as new stories shift the structure around due to Height To Next, with no option to insert a new storey at a specific height while keeping the other stories the same.
This window could have increased flexibility allowing you to insert new stories to match the structure, as well as more flexibility in general when adjusting stories.
