Hi Steve, could you show me in a screen shot or spreadsheet what you'd like to change the layers to?
Currently you can change the layer names to whatever you'd like yet you may find you have to update the scenes to reflect the changes.
Once you do this save the scenes as a template ( delete geometry and purge
go to File, save as template) this way everytime you open Sketchup it will remember the changes.
I'm interested in possibly creating a Cobie specific tool if there is sufficient need for it. It's anyone else here using COBie?
