[0002] In the fields of civil construction, electricity and chemical industry, with the improvement of standardization and the proposal of refined design requirements, more and more projects require the use of BIM three-dimensional design to solve various collision problems in the design stage and improve the design quality.

[0003] However, although BIM 3D design has good visualization and high precision, it takes a lot of time to configure the drawing environment to generate standardized drawings, and manual adjustment is required when the drawing range and scale are not set properly. Especially when pipeline 3D modeling requires single-line manufacturing ISO drawings to be produced one by one for each pipeline, the amount of drawings is huge, and manual modification of drawing names, drawing numbers and personnel information takes a lot of time and is prone to errors.

[0004] Different from the electric power, petrochemical and other industrial fields, the metallurgical industry involves a wide variety of pipeline media and parameters. Different process flows have very different requirements for drawing. Therefore, different template files need to be matched according to the project category. Therefore, it is very important to develop a highly intelligent and efficient drawing template system. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a pipeline three-dimensional information model drawing method and system to solve the problem that the drawing of three-dimensional pipeline design software is time-consuming and labor-intensive and cannot be consistent with actual projects.

[0013] In some optional implementation schemes, in step S1, efficiently configuring a three-dimensional drawing working environment on a standard drawing working environment template includes:

[0014] S11. Formulate the pipeline medium code included in the project, the pipeline model, center line, insulation layer, and line type corresponding to each medium; when drawing, the layer of the drawing should be consistent with the layer of the pipeline model, center line, and insulation layer;

[0015] S12. Formulate the pipeline numbering principles, as well as the names, attribute descriptions, and coding position numbering principles for various equipment, pipe fittings, valves, and instrument parts;

[0017] S14. Develop standardized drawing frames and legends for various types of equipment, pipe fittings, accessories, valves, and brackets in each view.

[0018] In some optional implementation schemes, by inputting or selecting keywords of project categories, the most suitable standard drawing work environment template is matched according to the project categories.

BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 Flowchart of the method for drawing a pipeline three-dimensional information model. DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] In view of the problems that the existing three-dimensional pipeline design software is time-consuming and labor-intensive to produce drawings and cannot match the actual projects, the present invention provides an efficient and intelligent pipeline three-dimensional information model production template system to improve the production efficiency and design quality of industrial projects, especially metallurgical industry projects after three-dimensional modeling, and belongs to the field of automatic extraction of pipeline three-dimensional information models and rapid and standardized production.

[0037] The method of drawing the pipeline 3D information model is as follows:

[0038] (1) According to the project category, batch selection or modification is performed based on the enterprise standard template to achieve efficient configuration of the drawing working environment of the 3D design software. The configured drawing working environment specifically includes the following contents:

[0039] (11) Formulate the pipeline medium code included in the project, the pipeline model corresponding to each medium, center line, insulation layer, line type, etc., and use this layer when drawing;

[0040] (12) Formulate standardized pipeline numbering principles, names, property descriptions, coding positions, etc. of various equipment, pipe fittings, valves, and instrument parts. The output layer is consistent with the layer used to set the model, center line, and insulation layer.

[0041] (13) Set the above names, attribute descriptions, and code numbers to be displayed on the drawing, in the position and format of the material and equipment table;

[0042] (14) Formulate standardized drawing frames and prepare illustrations for various types of equipment, pipe fittings, accessories, valves, and brackets in top, front, side, and perspective views in accordance with national, industry, and enterprise standards;

[0043] Since the project templates of the same category are automatically matched according to the mapping relationship in the project database (a variety of templates are customized according to the standards corresponding to different categories of projects, which better meet the actual project needs), there is no need to make major changes to the content, and only the designer needs to confirm it again, which further ensures accuracy and greatly improves configuration efficiency;

[0044] (2) Intelligently identify the drawing templates of the corresponding project category from the enterprise knowledge base and display them on the drawing interface for designers to confirm or manually switch to other categories of drawing templates.

[0045] (3) According to project requirements, the drawing range and direction (including top view, bottom view, left view, right view, front view, back view, southwest isometric, southeast isometric, northeast isometric, northwest isometric) can be quickly specified in the 3D view interface. The coordinate and elevation range can be selected, input or imported; and the range is displayed in real time in the 3D model interface for designers to review.

[0046] (4) After the designer selects the standard drawing, the plug-in automatically calculates and recommends the drawing scale that meets the company standard (including the automatic lengthening ratio of the drawing frame) based on the selected drawing range and the mapping relationship in the database, and supports manual modification and re-matching;

[0047] (5) Automatically read the PBS hierarchical information and personnel names at all levels in the project directory tree in the enterprise project management system through the RESTful Web API interface, and generate corresponding drawing numbers according to the drawing number generation principle;

[0048] (6) The generated project code, drawing number, discipline, drawing category, names of reviewers at all levels, and drawing scale are automatically entered into the information column corresponding to the template frame selected in (3) with one click, and displayed in real time on the drawing output interface for designers to review whether they match.

[0049] (7) Finally, call the standardized and customized element legend, code description, and material list template in the drawing template system to produce the drawing.

[0050] The present invention directly develops an intelligent drawing template system for pipeline three-dimensional information models on a three-dimensional design platform, realizing functions such as automatic matching, intelligent recommendation, and one-key entry, which has practical significance.

[0051] A specific implementation method is given below. Figure 1 As shown, the specific implementation steps are as follows:

[0052] 1. By entering keywords, the most suitable enterprise standard drawing work environment template is automatically retrieved according to the project category, so that designers can select or efficiently configure the 3D work environment. In the background database, the drawing work environment template has established a mapping relationship with the project category, so after the keyword matching is selected, the mapping relationship between the project and the standard drawing work environment template is automatically generated.

[0053] 2. Load the 3D drawing work environment configured in step 1. When creating a new pipeline 3D model, select the save path in the project directory tree, and the BIM model name will be automatically generated according to the pre-configuration;

[0054] 3. When the modeling is completed and the drawing is produced, the project information is automatically extracted from the enterprise project management system through the RESTful Web API interface;

[0055] 4. Intelligently select the drawing template corresponding to the project category based on the automatically extracted project information;

[0056] 5. The designer reconfirms the drawing template or manually switches to another type of drawing template;

[0057] 6. Designers can quickly specify the drawing range and direction (including top, bottom, left, right, front, back, southwest isometric, southeast isometric, northeast isometric, northwest isometric) in the 3D view interface according to project requirements. It supports point selection, input or import of coordinates and elevation ranges, and displays the range in real time in the 3D model interface for designers to review;

[0058] 7. After the designer selects the standard drawing, the system automatically recommends the company's standard drawing scale (including automatic lengthening of the drawing frame) according to the selected drawing range, and embeds the drawing frame in the drawing interface for the designer to review, and the drawing range supports manual modification and re-matching;

[0059] 8. Based on the project information extracted in step 3, the system automatically generates the project code, drawing number, specialty, names of reviewers at all levels, and drawing scale, and fills them into the corresponding information column of the drawing frame embedded in step 7 with one click;

[0060] 9. Finally, call the standardized and customized graphic element legend, code description, and material list template in the drawing template system to produce the drawing.

[0061] In summary, the present invention provides an intelligent drawing template system for a pipeline three-dimensional information model. The functions of the drawing template system include: efficient configuration of a three-dimensional drawing working environment, visual selection of drawing range, direction, and elevation, intelligent recommendation of drawing scale, automatic matching and extraction of project, personnel and other information and one-click filling of the drawing frame, standardized customization of graphic elements and material lists, etc. The specific implementation steps are as follows: efficiently configure the 3D working environment based on the enterprise standard template according to the project category; when creating a new pipeline 3D model, after selecting the save path in the project directory tree, the BIM model name can be automatically generated according to the pre-configuration; when the modeling is completed and the drawing is produced, the project information is automatically extracted from the enterprise project management system through the RESTful Web API interface, and the drawing template corresponding to the project category is intelligently selected; after the designer confirms the selected template for the second time, the drawing range, direction, elevation, etc. are quickly specified in the 3D view interface. The plug-in automatically recommends the enterprise standard drawing scale based on the selected drawing range and embeds the drawing frame in the drawing interface; the automatically generated project code, drawing number, personnel information at all levels, and drawing scale are filled in the corresponding information column in the template frame with one click; finally, the standard customized element and material list template are called to complete the drawing.

[0062] It will be easily understood by those skilled in the art that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
