Odiemanc, Your sphere was probably a primitive sphere so you cant really edit the vertices unless you convert the sphere primitive to a mesh. You do this in the "model room"(double click sphere to enter model room). Under the "edit" menue select "convert to other modeller" ,then select vertex modeller, then "Okay". You should now see all the vertices of the sphere. Try inserting a vertex object instead and then "insert" a sphere. Good luck. Mike
