I spent many years now using 3D for ship or yacht design.. For the most part I prefer Microstation.. & years ago I was using it for all aspects of the Engineering on Yachts.. Then it was call Microstation modeller.. I'm now in a very different position in design but still using the modern version Triforma and Bently structure.. Still very Powerful but I do find it doesn't work any where near as good as Modeller.. So many things are't possible now!!!! Wake up Bently!!!
But!!!! Unigraphics is storming the 3D world right now. Its all you need.. Unfortunately we dont use it where I',m working now but we are looking into finding a new all round package.. Hopefully Unigrafix
