I like how easy it is to use this software for creating 3D models using drawings from 2d planar surfaces (elevations). It's also very flexible when working out what you need as far as parameters go - which makes life easier! The only problem i have found sofar has been that there are not many tutorials available online/in books etc., but once they do become more widely known then all will be well again :) For those who want their own CAD model made quickly without having lots experience or knowledge about designing ships; just get yourself one copy first time round because otherwise your going spend ages getting used too its features before being able make any progress atall!! Creating ship design plans quicker than other programs &-or drawing them up myself instead!
