Abstract

This paper proposes a novel approach to convert a 3D scan to its CAD counterpart. The objective is to extract intermediate sketch planes that well represent the input scan and are close enough to the original design intent. These sketches can then be easily converted into CAD models automatically due to their faithful representation of the input geometry. One objective is to avoid incorporating user/company dependent content in the CAD reconstruction process. The intermediate representation shall be directly supported in any CAD environment to boost the designer’s work without the need of supplementary (model conversion, automatic feature recognition) steps. Nowadays, it is common to digitize an object and reconstruct its geometric primitives. However, this reconstruction contains only geometry. In literature, the final goal might be met by recovering the modeling tree itself, by means of automatic feature recognition, and converting to the proper format of a specific CAD software package. However, the constructed tree and its conversion introduce issues in the reconstruction process. The definition of an exact modeling tree, and the production of a meaningful final CAD model are rather hard to obtain. This imposes a rather inefficient working method, thereby heavily impacting the designer’s modeling skills.
