Claim One:
1. A process for making a mold's molding surface comprising producing the molding surface based at least in part on computer-implemented modeling that predicts/estimates changes in a target shape of a three-dimensional glass cover resulting from ion exchange strengthening, said ion exchange strengthening comprising ion diffusion and said glass cover comprising a planar central portion and a perimeter portion which (i) borders at least part of the planar central portion and (ii) extends out of the plane of the planar central portion to provide the glass cover with three dimensionality, said perimeter portion having a perimeter edge, wherein: (a) said computer-implemented modeling comprises modeling the effects of ion exchange through the perimeter edge by employing a boundary condition at the perimeter edge; and (b) in said computer-implemented modeling, said boundary condition permits ion permeation through the edge.
