Description

Technical Field

[0001] This invention relates to the field of geological 3D modeling and BIM application technology, and particularly to a method for generating 2D maps from 3D geological models. More specifically, it is a method for generating 2D maps from 3D geological models based on the 3DE platform. Background Technology

[0002] With the widespread application of forward 3D design, geology is gradually transforming from the traditional 2D mapping model to forward 3D design. However, due to the relatively lagging industry standards for 3D mapping, 3D geological modeling has not yet been fully adopted. Engineering technicians still maintain their old mapping habits, requiring them to devote significant time and effort to drawing geological plan and profile diagrams. 3DEXPERIENCE Platform (3DE), launched by Dassault Systèmes in 2014, is a product development software application platform that integrates numerous digital design and simulation modules such as CATIA, ENOVIA, DELMIA, and SIMULIA. It enables 3D design, engineering, 3D CAD, modeling, simulation, data management, and workflow management.

[0003] While 3D geological models built on the 3DE platform can be used to generate 2D maps, the directly outputted maps are not standardized geological profiles and require further improvement. The 3DE platform also lacks standard pattern libraries, line type libraries, and legend libraries.

[0004] Therefore, it is necessary to develop a method for automatically generating two-dimensional maps of three-dimensional geological models on a 3DE platform. Summary of the Invention

[0005] The purpose of this invention is to provide a method for generating two-dimensional geological maps from three-dimensional geological models based on the 3DE platform. This method is a standardized two-dimensional geological mapping method based on 3DE geological models, enabling one-click drawing of patterns, line types, and legends, customizable map labels, and standard output of two-dimensional cross-sectional views. It achieves automatic two-dimensional mapping of three-dimensional geological models under the 3DE platform, improving work efficiency and solving the problem that existing two-dimensional geological mapping under the 3DE platform cannot be automated.

[0006] To achieve the above objectives, such as Figure 1 As shown, the technical solution of the present invention is: a method for generating two-dimensional maps from a three-dimensional geological model based on a 3DE platform, characterized by including the following steps:

[0022] Step 1b3: Double-click the line type to access the line type editing interface and draw the line type;

[0023] Step 1b4: Configure the generated XML file in the standard folder;

[0024] The method for establishing the image label library is as follows:

[0025] Step 1c1: Create an engineering drawing and name it "Drawing Sign Library";

[0026] Step 1c2: Add a detailed engineering drawing at a scale of 1:1;

[0027] Step 1c3: Add a 2D component to the template toolbar and draw a label starting from the origin of the coordinate system.

[0028] In the above technical solution, the method for establishing the cross-sectional view in step two specifically includes the following steps:

[0030] Step 22: Generate a profile using the native profile view command;

[0031] Step 23: Rotate and translate the generated section view.

[0032] In the above technical solution, step three, automatically drawing the ruler, specifically includes the following steps:

[0033] Step 31: Obtain the CATIDftGenGeomAccess interface of SectionView to get all IDMCurve2D;

[0034] Step 32: Iterate through all IDMCurve2Ds and obtain the containing box of each IDMCurve2D;

[0035] Step 33: Add all the containing boxes into one containing box and calculate the minimum and maximum coordinate values ​​of the containing box;

[0036] Step 34: Draw a ruler based on the bounding box coordinates.

[0037] In the above technical solution, step four, which involves automatically drawing the label, specifically includes the following steps:

[0043] In the above technical solution, step five, which involves automatically drawing the borehole, specifically includes the following steps:

[0044] Step 51: Obtain the associated 3D model through the View of the cross-section;

[0045] Step 52: Obtain the root node of the 3D model and traverse the structure tree of the 3D model to obtain the borehole coordinates (zx1, zy1), bottom coordinates (zx2, zy2), and borehole name (zk) of all boreholes;

[0046] Step 53: Traverse the boreholes and profile lines, and use the MinimumDistance function to obtain the nearest distance d between the profile line and the borehole point, the index of the profile line segment where the nearest distance is located, and the intersection point p of the nearest distance profile line;

[0047] Step 54: Traverse the profile lines in order. If the index is equal to the profile line segment number, obtain the length from the starting point of the profile line segment to point p. If the index is not equal to the profile line segment number, obtain the length of the profile line segment. Finally, add all the lengths together to obtain the projected distance h from the borehole point to the profile line.

[0048] Step 55: The borehole's opening coordinates in the cross-sectional view are (minx+h, zy1), and the bottom coordinates are (minx+h, zy2). Draw the borehole line based on the opening and bottom coordinates.
