Convert Bsurface (without object) to mesh I am trying to join 3 objects. They should be 3 meshes (which i created starting from bsurface). Somehow when i try to join them it says "Active object is not a selected mesh". Also the mesh icon does not appear. Alt+C seems not to do anything. How can i convert it to a mesh!! 
Thanks for your help,
Lluís
I belive the problem resides in that i made a retopo with bsurface but without the 1st step (add a object -> enter edit mode-> delete the plane-> start! ). Nevertheless i can see it like this: 


*(Outliner View. Objects: Plane, Plane.001 and Plane.00)
Found my answer in this comunity and blenderartist.The problem was that i needed to click on the little arrow (selection off/on) next to the object.
Wasn't aware of that. 
Thanks, lluis
