舰船建模技术技术, structure, generated, computer, currently舰船建模技术Below are some pictures of my making of French early ships. Im currently working on :- Battleship Hoche- Battleship Bouvet- Armored cruiser Pothuau- Armored cruise Jeanne dArc(each ship at both 1:700 and 1:350 scale)I started from the official Navy plans. I put the files in my computer and extracted the hull frames and longitudinal sections. Heres an example with Hoche :下载 (95.39 KB)舰船建模技术1小时前then I computer generated the whole hull structure at both scales (again the Hoche) :下载 (119.87 KB)舰船建模技术1小时前child 发短消息 加为好友 child 当前在线 UID43662帖子275精华0积分704威望283 金钱0 在线时间4 小时注册时间2012-3-19最后登录2012-4-15I photo etched my project to get a full set of frames and bow + stern structures (Heres Bouvet 1:700) :下载 (65.5 KB)舰船建模技术半小时前I assembled both hull parts (I planned a waterline option, hence the two parts). Heres Hoche again :下载 (28.57 KB)舰船建模技术半小时前Then came the filling stage. I used sawn blocks of prototypying board, which is a silica bonded polyurethane resin board used in the industry to make prototypes for casting. This excellent product is worked like balsa wood, but remain stable and watertight for wet sanding. Blocks roughly traced using the brass frames as templates, then roughly cut with an electromagnetic vibrating wire saw and glued in place with Zap-a-Gap, with brass photo etched frames inserted.The sanding step was very easy : one had just to sand the block until the paper touches the brass frames which are harder, making a different noise on them. This rumble noise was the signal to stop. Using this simple way I managed to shape the hulls quickly without using any gauge, template, measurement and I got a shape accuracy about 0.1mm.z 发短消息 加为好友 child 当前在线 UID43662帖子275精华0积分704威望283 金钱0 在线时间4 小时注册时间2012-3-19最后登录2012-4-15Heres Hoche before and after :下载 (53.2 KB)舰船建模技术半小时前Heres the 1:350 Pothuau under assembly (both hull parts simultaneously) :下载 (69.75 KB)舰船建模技术半小时前z 发短消息 加为好友 child 当前在线 UID43662帖子275精华0积分704威望283 金钱0 在线时间4 小时注册时间2012-3-19最后登录2012-4-15 My fleet (1:350 and 1:700). Fromto bottom : Jeanne dArc, Bouvet, Hoche Pothuau下载 (66.43 KB)舰船建模技术半小时前Im now doing the decks, hull sides and superstructures, using sawn blocks of bonded resin entirely covered with photo etched plates. Doing all this photo etching is very long, although I just have to redraw each part directly on the original plans (almost no measurements + 100% accuracy).Heres Pothuau again. On the bottom are shots from the original plans inserted into my CAD software. Above are the drawings, scaled down
