Abstract
In this paper, the authors present a new algorithm for constructing a solid model when the given input is only one partial-view sketch (“natural sketch”). This algorithm is a two-step process, where first a complete (wireframe) sketch is derived, which is then transformed into a 3D polyhedron. The paper details topological and geometric aspects of the process, as well as the essential “user-interaction” components dealing with cases where the sketch-to-solid problem does not have a unique solution.
