Description
Technical Field
The disclosure relates to the technical field of engineering drawing layout, in particular to a quantitative evaluation method and a quantitative evaluation system for engineering drawing layout quality.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
CAD and other research and development design industrial software are imperial crowns in industrial software and are taps of intelligent manufacturing industrial chains. The engineering drawing is a schematic file for product design and manufacture, contains a series of information such as two-dimensional expression, size annotation, material detail and the like of parts, and the readability of the engineering drawing is determined by the arrangement order of the engineering drawing and the aesthetic property of the layout, so that the efficiency of product design and manufacture is affected.
In recent years, although three-dimensional CAD rapidly develops in domestic and foreign markets, the inability to rapidly generate a three-dimensional model to a two-dimensional engineering drawing is always a key pain point which puzzles the popularization of three-dimensional design software. The manual drawing is complex in operation, and a large number of designers with industry experience are needed, so that a large amount of manpower and time resources are wasted. Therefore, realizing automated drawing has important significance for improving design efficiency and design quality. In the automatic drawing process, automatic generation of drawing layout which meets industry standards and is attractive is a very key link. Nowadays, engineering drawings mostly adopt a manual drawing method, the layout of the drawings is mostly determined by subjective factors of designers, and the standardization degree is low.
Therefore, some CAD software can realize automatic layout by summarizing the drawing standard, but when realizing automatic layout of engineering drawings in CAD software, a large number of layout results are enumerated, but the quality of the layouts is different, but for a large number of good-and-bad drawing layouts generated in the software, there is no effective method for screening the layouts, and the automatic drawing layout is not capable of quickly determining and rendering the optimal layout, so that the automatic drawing efficiency is low.

Drawings
The accompanying drawings, which are included to provide a further understanding of the disclosure, illustrate and explain the exemplary embodiments of the disclosure and together with the description serve to explain the disclosure, and do not constitute an undue limitation on the disclosure.
Fig. 1 is a general flow chart of a quantization scoring method in an embodiment of the present disclosure.
The specific embodiment is as follows:
the disclosure is further described below with reference to the drawings and examples.
It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present disclosure. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments in accordance with the present disclosure. As used herein, the singular is also intended to include the plural unless the context clearly indicates otherwise, and furthermore, it is to be understood that the terms "comprises" and/or "comprising" when used in this specification are taken to specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof.
Example 1
In one embodiment of the present disclosure, a method for quantitatively evaluating layout quality of engineering drawings is provided, as shown in fig. 1, including:
step one: acquiring an engineering drawing to be evaluated, and constructing an index for quantitatively evaluating the engineering drawing;
step two: performing scoring calculation of five evaluation indexes of a view arrangement mode, a view proportion, a graph, a node diagram arrangement mode and a table arrangement mode on the engineering drawing;
summing and sequencing the scoring calculation scores of the five evaluation indexes, and determining an optimal layout automatically generated by software;
step three: and rendering the drawing to complete automatic generation of the engineering drawing.
As an embodiment, the specific method for calculating the scores of the five evaluation indexes includes:
(1) View arrangement pattern score computation
For the view placement mode, views are sometimes split from the middle in order to save drawing space. But the readability of the drawing is reduced after the splitting. Therefore, for view placement mode, the middle split is assigned a score of-50, and the split is not assigned a score of 0.
(2) View scale score calculation
The view scale has important significance for the definition and readability of the drawing. However, for evaluation of the view ratio, not only the definition and readability of the view (the view ratio is too small and unclear) but also the waste of drawing space caused when the view ratio is too large must be considered. For evaluation of view proportion, a piecewise function is fitted empirically to realize evaluation of view proportion.
Piecewise function:
taking the diameter of the cylinder drawing surface as 60 as a clear boundary, fitting the following functions:
let the diameter of the cylinder drawing be x and the score be score
(3) Map scoring calculation
For the same device, a plurality of different sizes and numbers of pictures can be selected when the pictures are drawn. In industry specifications, only the main drawing and not the additional drawing are used as much as possible without affecting the definition and the readability of the drawing. Accordingly, the present disclosure separately assigns to different drawing sheets: a1, A2, A3 are assigned 0 points, A1 x 1.25 (A1 is added with 1/4 of A1), A1 x 1.5 is assigned-20 points, A1 x 1.5 is assigned-40 points. And so on.
(4) Node map placement mode scoring calculation
When a specific device is mapped, the node map is required to be put on the main map as much as possible in the industry specification, and when the space of the main map is insufficient, the node map is put on the additional map. Therefore, the node map layout pattern is located at the main map 0 point and at the additional map-50 point.
(5) Form arrangement scoring calculation
In the engineering drawing, the arrangement rule of the table is the same as that of the node diagram. Therefore, for the form placement mode, the main frame is assigned a score of 0 and the additional frame is assigned a score of-50.
Finally, the scores of the five evaluation indexes are summed and sequenced, the optimal layout automatically generated by software is determined, drawing rendering is further carried out, and finally, automatic generation of engineering drawings is completed.
