It would be great is Serraview would use xdata in the autocad files to link polylines, space names and space types to an internal space id. This way when you change a space name or space type in autocad and re-import it, it wouldn't need to completely delete the space record and re-create it. This deletion and re-creation removes all allocations and people assignments along with any other settings that are not default to the space type. This is a very limiting way to manage the drawing data that does cause issues with data lose when you don't effectively work around it.

Also, It would be possible to allow for a future space layer to be created for new workstations or rooms to be created in the drawings with space names, that could be used in BOS plans and then later promoted to real spaces when the bos plan is ready to publish. I have seen features like this in another CAFM systems that is now discontinued. Please feel free to contact me for more details if this is of interest to the development team.
