Contributions from Richard mostly, but Tracy on occasion. Albert unfortunately, is no longer with us to type his thoughts - however as most of them were unprintable, it's probably better that he can't type them.
Richard's a Mechanical Engineer specialising in Stress Analysis. Due to the poor state of Finite Element Modellers he's spent a fair bit of time writing translators to enable packages like Poser, Studio, Truspace etc to act as modellers for mechanical products. Why not use CAD.. Because the file formats are too complex! Tracy is a Library assistant in Europe's largest learning resource centre (University library & computer department to most!). We used to have a character cat called Albert. He features in a picture or two.
