3D modeled object representing a manufacturing product

A non-transitory computer readable medium having stored thereon a program for designing a 3D modeled object representing a manufacturing product that when executed by a computer causes the computer to implement a method comprising:

• obtaining a base mesh representing the 3D modeled object;
• selecting one or more connected edges of the base mesh, thereby obtaining a path of connected edges comprising two endpoints;
• subdividing the base mesh based on the path of connected edges by:
• obtaining a bevel pattern area over the path by:
• identifying each face of the base mesh that shares an edge of the path,
• subdividing each identified face of the base mesh for reaching a number p of cuts where p is a non-negative number, a cut being a face subdividing the identified face of the base being swept along at least one of the one or more connected edges sharing the identified face, when p equals zero, the identified face being subdivided by a face sweeping along the at least one of the one or more of the connected edges of the base mesh, when the p is greater than zero, the face being created at the face being subdivided by faces bounded by p edges sweeping along the face;
• and
• obtaining, for at least one of the two endpoints of the path, a transition area by grouping all faces sharing the at least one of the two endpoints of the path, except those of the bevel pattern area;
• re-meshing the transition area by:
• obtaining, for each cut comprising a pair of vertices, a transition vertex located in the transition area, wherein obtaining the transition vertex located in the transition area includes:
• computing a fictive line that extends between:
• a fictive vertex located on an edge shared by both the bevel pattern area and the transition area, and
• a convergence vertex that is located on one of the edges of the transition area;
• and
• placing the transition vertex located on the transition area on the fictive line, and
• computing an edge connecting each vertex of the pair of vertices of the cut with the obtained transition vertex;
• and
• outputting the subdivided base mesh, the subdivided base mesh being suitable for manufacturing the product.
