Description
Technical Field
The invention belongs to the field of ship body drawing and design, and particularly relates to an automatic drawing method, system, equipment and storage medium for a ship structure diagram.
Background
The hull is assembled by a large number of criss-cross grillage and secondary structure, and the grillage is composed of plate and reinforcing material, referring to fig. 1, when the a grillage is assembled with the B grillage, the section bar of the a grillage must be kept continuous due to the factor of structural continuity, and therefore the B grillage must be provided with corresponding cut-outs for the section bar of the a grillage to pass through, these cut-outs are called through holes C, on the other hand, due to the factor of strength or tightness, it may be necessary to provide sealing plates at the through holes, and the sealing plates are called complementary plates D.
In the prior art, drawing methods of through holes and patch boards mainly include the following three methods:
1) drawing by a basic geometric drawing function. On the basis of basic geometric elements such as straight lines, circular arcs and the like, drawing of the target graph is gradually completed through methods such as deviation, rotation or trimming and the like, and means such as auxiliary lines and the like. The most basic graph drawing method is complex and tedious in process and low in efficiency.
2) Drawing by inserting tiles. On the basis of the method, the commonly used through holes and patch boards are combined into a block, and the block is directly inserted under the condition of meeting the condition to finish the drawing of the target graph. This method can simplify the drawing process to some extent, but the blocks are only suitable for drawing through holes and patches with specified sizes of parts.
3) And finishing the drawing of the target graph by copying and pasting on the basis of the existing graph. The limitation of this method is that only through holes and patches of the same size and angle can be drawn, and it cannot be applied to the case where the border of the panel frame is curved.
In addition, after the drawing of the target graph is finished, the graph elements of the color, the line type and the line width of the graph are manually set, so that the graph can be further standardized, and the automation degree is low.
