Solid modelling is a core technology in VLSI process and device modelling. Intel has found that commercial software can be unreliable and slow. An important example is computing an offset of a polyhedron. Prior work on robust computational geometry makes assumptions that conflict with the application requirements, notably the need to perform finite-element analysis on solid models. I will describe preliminary work on a robustness technique that meets these requirements. I will present a novel approximate offset algorithm that I have implemented using this robustness technique. I will conclude with a discussion of the outstanding problem of eliminating small features from polyhedral meshes.
