REVERSE ENGINEERING SUPPORT APPARATUS

A free curved surface and an analytic curved surface can be generated as intended by a user with a simple operation. A reverse engineering support apparatus includes: a shape attribute setting unit that sets a shape attribute to a polygon included in mesh data; a region specifying unit that specifies a region included in the mesh data based on a shape attribute; a data conversion unit that converts a polygon included in the specified region into surface data based on the shape attribute and converts a polygon not included in the region into surface data of a free curved surface; and an output unit that outputs pieces of the surface data created by the data conversion unit as CAD data.
