A BREP Model and Mesh Errors Detecting Tool: TopoVisu

This paper aims to describe the methodology behind the computer aided design tool TopoVisu. The objective of this tool is to support analysts and designers in their work, mainly by helping detect errors in models and meshes. But the error detection is not the only feature of TopoVisu, it also provides a visualization environment to cope with data portability issues. The paper briefly describes the type of problems that may be detected through the tests implemented in TopoVisu, and the PDF 3D exporting tool implemented as a mean of documentation and communication of the models and their validation.
