Described is a method and system providing a dynamic, live surface andor model elements to complement and enhance what is being modeled or visualized, enabling the addition of new features and functionality to visualization and modeling tools. The technique involves use of an adjustment circuit operatively connected to the bias-generator, where the adjustment circuit is controllable to facilitate a modification of a voltage output by the bias-generator. Managers are provided to control each of the editors and for maintenance of historical information to allow auditing and modification monitoring. Inserts according to the invention exhibit favorable edge strength and thermal shock resistance.
