Abstract

The invention relates to a drawing processing method and device based on a hull structure three-dimensional model and a storage medium. The method comprises the steps: recognizing and displaying large-assembly-base-plane jointed board parts, marking design information, and generating large-assembly-base-plane jointed board subgraphs; identifying and displaying large-assembly longitudinal bone parts, marking design information and generating large-assembly longitudinal bone sub-graphs; identifying medium-assembly parts, displaying the medium-assembly parts step by step according to the assemblysequence, labeling design information for the medium-assembly parts corresponding to each step, and generating corresponding middle-assembly sub-graphs; identifying small-assembly parts, displaying the small-assembly parts step by step according to the assembly sequence, marking design information for the small-assembly parts corresponding to each step, and generating corresponding small-assemblysub-graphs; and conducting identifying to obtain a part which is not drawn, and labeling design information to generate a residual sub-graph. Compared with the prior art, design information is displayed and marked in batches according to the assembling sequence, and meanwhile assembling personnel can be clearly guided to assemble parts in sequence.

Description

technical field [0001] The invention relates to the field of ship design and manufacture, in particular to a drawing processing method, device and storage medium based on a three-dimensional model of a hull structure. Background technique [0002] As the full 3D design of hull structures becomes more and more common, drawing based on 3D models of hull structures has become a key design method for ship design. [0003] In the existing technology, it is generally to extract each two-dimensional section from the three-dimensional model, and mark the design information on the two-dimensional section for drawing. This method is relatively simple to implement, but one section often expresses many small pieces of independent information at the same time. Large group part information, and medium group component information. The information is very disordered, which is not conducive to the subsequent reading of the drawings. [0004] In order to solve the above problems, some techn...
