I just sat through 4 days of ETO training using the Autodesk Official Training Courseware (AOTC) material. The course was fantastic and the material eases you into ETO whilst remaining a good reference guide. (Wish the course had been much longer as it was so good!) Not sure if you can buy the book on its own (you'll need the support files, otherwise it's pointless) - try your local reseller? Peter
