Ship hull plate mark lofting method

Abstract

The invention discloses a ship hull plate mark lofting method. The method comprises the following steps: the step 1, using an Excel table for carrying out statistical input on feature information of ship hull plate marks, transversely arranging and counting all information features, and forming an Excel statistical table; the step 2, importing the Excel statistical table and the corresponding character library into a ship hull plate sign generator; the step 3, bridging the feature information in a ship hull plate sign generator, then calling CAD software to cut the bridge according to the outer contour of the graph of the feature information, and finally calling a PEDIT command to convert the graph into a merged multi-segment line closed graph to generate a final character string graph; and the step 4, outputting the feature information of the ship hull plate mark, wherein the feature information is located below the character string graph. According to the ship hull plate mark loftingmethod, automatic lofting of the ship hull plate is achieved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a method for setting out marks on the outer plate of a ship. Background technique [0002] At present, the outer plates of various ships are equipped with hull outer plate marks, such as subdivision marks, rib position marks, cabin names, etc. Most of the outer plate marks are composed of strings of numbers and letters, which are made of steel plates and welded to the hull. outer panel. At present, most of the hull plate marking parts are drawn by hand by designers, and then strings are arranged and connected by bridges according to the specific character height, character spacing and other requirements, and finally the outer plate mark lofting parts are formed. The traditional manual stakeout mode has the following disadvantages: manual stakeout has a large amount of repetitive work, the number of parts is missing, characters and heights are error-prone, and it is difficult to sort parts on site.
