FIELD: computing technology.
SUBSTANCE: technical result is achieved by means of the stages wherein: in the CAD system model configured to represent the product as algebraic geometry or faceted geometry, the mesh geometry constituting the surface of the product in 3 dimensions is set; the limitations to be applied to the mesh geometry are set; the mesh geometry is solved as an exact surface; and the updated model of the mesh geometry is saved.
EFFECT: increased accuracy of realisation of the limitation applied to the faceted surface of the hybrid model, avoiding additional fluctuations or waviness that could occur in the approximation.
