Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] The present invention provides a kind of digital design method of ship general drawing based on AutoCAD and PDM, as attached figure 1 As shown, the steps of this method are as follows:

[0030] Step 1. The administrator creates a new ship model product Product_N in the PDM interface data submission system;

[0031] Step 2. The administrator creates an area structure tree in the area browser of the PDM interface data submission system according to the composition of the watertight area and deck of Product_N;

[0032] Step 3. According to the overall design requirements of the ship, the general professional defines the "cabin space position" interface relationship of the product Product_N in the interface coordination definition module of the PDM interface data submission system, which includes interface attributes: bottom, top, cabin bottom area, an...

Abstract

The invention discloses an AutoCAD and PDM-based digital design method for a ship general drawing. According to the method, names, numbers and geometric information of a deck and a cabin in the ship general drawing are stored on a boundary line of the deck and the cabin of a two-dimensional drawing in an extended data format; an algorithm derived based on a Cauchy theorem and a Cauchy integral formula can judge the deck which the cabin belongs to; a cabin interface, a deck interface and a region structure tree for describing the ship general drawing are established in PDM; and an interface integrated with the PDM is developed in AutoCAD, so that general drawing design personnel can draw a digital general drawing in an AutoCAD environment and perform real-time release, and the digital general drawing in the PDM can be dynamically loaded. The method can effectively improve comprehensive analysis capability of ship general arrangement information, and lays favorable conditions for automatic design of systems of apparatuses, ship guarantee, power and the like, automatic extraction of gravity center of weight of a device and automatic arrangement of a three-dimensional model of the device.

Description

technical field [0001] The invention belongs to the field of ship digital design and relates to a method for digital design of ship general plan based on AutoCAD and PDM. Background technique [0002] In the overall design process of the ship, due to the large number of cabins, the geometric shape of the cabins is relatively complex. Some cabins span multiple decks, and the geometric shapes of the cabin roof and tank bottom of some cabins are inconsistent. During the release of each version of the general plan, in order to Familiar with various design parameters related to decks and cabins, it is necessary to calculate and summarize the cabin area and volume of the whole ship, and also need to know the position information of the cabins on the deck. A large number of calculations seriously affect the work efficiency of professional designers. [0003] At present, the overall professional designers mainly carry out the management and release of 2D general drawings based on Au...
