Is there a way to add new data to an existing SSA project, such that the new data is properly georeferenced. I need to add subbasins, split some subbasins, add pipes, etc. The only way I've found to do this, is to make the changes in CAD and import to a new SSA file... which I don't want to do. This also loses a lot of data as my open channels, inlet types, etc. are lost in the transition (I'm assuming because such items are not defined in CAD). SSA 2012 Thanks
