Abstract: We present a sketch-based modeling system for interactive modeling of a variety of 3D objects. The idea is to con-struct and modify 3D objects, step by step, using a 2D template topology library. The library, called T-LIB, consists of 2D Edge Graphs and the corresponding algorithms to construct and modify 3D objects. The local part of 3D ob-ject around the sketch lines is analyzed as a 2D Edge Graph. Once the Edge Graph can be matched to a template of T-LIB, the 3D object can be generated in a basic shape reconstruction procedure, or modified in a 3D shape modi-fication procedure. After obtaining the solid model, we use a fillet operation and a subdivision method to generate smooth surface objects.
