Abstract	During the conceptual design stage, the design engineers usually sketch their design ideas. For those sketches, the skeleton of the design idea can be created with lower dimensional primitives like lines, arcs, etc. In this paper, we focus on skeletal modeling, which is an approach to creating solid models in which the engineer designs with lower dimensional primitives such as points, lines, and triangles. The skeleton is then “skinned over” to create the surfaces of the three dimensional object. Then the convolution surfaces are generated by convolving a kernel function with a geometric field function to create an implicit surface. We propose that skeleton, even it is simple, contains important design information, such as the geometric, topology that defines the design concept. It is very important to keep the topology of the skeleton and thus the important information that defines the design concept, i.e, the geometry of the product, the functionality of the product determined by the topology of the design. We assume that design engineers expect the topology of a skeletal model to be identical to that of the underlying skeleton. In this paper, the system is described and some examples are illustrated to use the skeletal based modeler.
