✦ Synopsis

This paper presents a method for computing offsets of profiles on three-dimensional surfaces based on processing the intersections of the offset segments. The method does not assume a particular curve representation of the profiles. It covers both closed and open profiles. A twostage approach of first constructing the local and then the global offset of the progenitor profile is adopted. Conditions governing the construction of those offsets are presented and used for the construction.
