Help absolute beginner with sub interior creation

ps unweld the hatches for the decoys and the torpedo loading cover on the bow, they will look much better. however make sure every plane surface is weld in order to create a smooth surface, but planes going 90° to each other shuld not be weldet so you maintain sharp edges were they are supposed to be. uv mapping-never mind, youll get through that as well, the sub looks grat right now and i know that aching wrist much too well...good job buddy!
