The paper developed a platform to share resources of mechanical production based on PaaS considering small and medium company not have enough fund to build website to advertise production. The platform has a 4 layers architecture, applying X3D to display 3D model, SAI used to realize interaction dynamic. Thinking about the characteristic that mechanical product contain much non-structure data, files of X3D and 3D model that can be index via MechanicalProductionList table were not keep in database for saving space. The platform can meet the increasing of users for having the scalable ability. The platform render 3D models quickly, interactive strongly, can advertise production powerfully.
