We propose a method that efficiently managing and downloading a family of 3D models with similar shapes. In our method, a model is decomposed into a set of cells so that any form-feature of the model can be represented by a combination of the cells. This method allows a variety of 3D models to represent in a single data structure. When the user edits the model on a browser, the system downloads necessary cells according to user's request, and newly downloaded cells are merged into the current model on the client side. Since our system does not apply Boolean operations in run time, the client-side system is very efficient and easy to implement, for example, by using Java.
