[0021] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The following is combined with Figure 1 The web-based 3D component model assembly method is exemplified. The method includes the following steps:

[0023] Step 101: In response to triggering an operation to import a three-dimensional component element to be combined, the three-dimensional component element is imported into a canvas of a web page.

[0024] In this embodiment, a webpage for constructing a component model is presented on the web client. One or more 3D component elements can be imported by triggering the file import button on the webpage. Multiple 3D component elements can be imported if desired. 3D component elements can also be imported from an element library by triggering the component on the webpage.

[0025] The element library is a 3D model library of the smallest subdivided elements of parts and components, as well as a 3D model library of parts and components products in various industries. It compresses 3D models in a lightweight manner to facilitate fast transmission and loading on web and mobile terminals, including 3D models, 3D dimensioning information and corresponding reference coordinate systems.

[0026] refer to Figure 2 Taking the import of 3D component elements from the element library as an example, the import operation of a 3D component element is triggered on the page, and then it is displayed in the canvas area.

[0027] Step 102: When a drag operation is triggered on any of the three-dimensional component elements to be combined in the canvas, the dragged position is detected.

[0028] In this embodiment, after the import operation is performed, the imported three-dimensional component elements are presented in the canvas. The user can drag and combine the three-dimensional component elements in the canvas area, and detect the current position during the dragging process so that they are automatically adsorbed after reaching the preset position.

[0029] Step 103: When the dragged position reaches a preset position, the dragged any three-dimensional component element is automatically adsorbed to the target three-dimensional component element, wherein the preset position is determined based on the position of the target three-dimensional component element.

[0030] In this embodiment, once the dragged three-dimensional component element reaches the preset position, it is automatically adsorbed without the need to select the target three-dimensional component element. This method greatly enhances the efficiency of model construction and avoids the problem of easy errors caused by the selection combination method.

[0031] Furthermore, the combined and customized parts are stored in a combination standard database, which records data information such as the unique ID number, size parameters, material properties, and the order and position relationship of each element or part in the combination of the smallest subdivided element referenced by the combination, and is given a combination ID number.

[0032] As an optional implementation method of this embodiment, when the dragged position reaches the preset position, the dragged any three-dimensional component element and the target three-dimensional component element are automatically adsorbed, including: detecting the first reference coordinate system preset at the junction point of the any three-dimensional component element, and the second reference coordinate system preset at the junction point of the target three-dimensional component element; when being dragged, detecting the distance between the origin of the first reference coordinate system and the origin of the second reference coordinate system; if the distance is less than a preset threshold, aligning the first reference coordinate system and the second reference coordinate system to complete automatic adsorption.

[0033] In this embodiment, each three-dimensional component element is provided with a plurality of joint points based on the assembly rule, and each joint point has a corresponding reference coordinate system. Figure 3 , the three-dimensional component elements are preset with a reference coordinate system for automatic combination and adsorption, including the origin coordinates, x-axis, y-axis, and z-axis, which are marked with the matching reference coordinate system in the figure. Different three-dimensional component elements can be automatically combined based on the reference coordinate system at the junction by dragging. When being dragged, when the distance between the junction points is less than the preset threshold, such as 10mm, the aligned three-dimensional component elements are aligned through the reference coordinate system of the junction point and combined into one. Different three-dimensional component elements combined into one can also be separated by dragging.

[0034] When different 3D component elements are automatically adsorbed, they are aligned based on the same spatial coordinate system principle and the origin position coincidence calculation is performed based on the origins of the two reference coordinate systems to calculate the movement data in the canvas. Based on the movement data, the dragged 3D component element is moved so that it coincides with the reference coordinate system origin at a certain junction point of the target 3D component element.

[0035] For example, the origin, x, y, and z axis vectors of the reference coordinate systems of all elements in the combined view are traversed. When a reference coordinate system on a three-dimensional component element is selected and dragged toward the target element, the system automatically identifies and determines the relative distance between the coordinate system selected by the dragged element and the origin of the coordinate system of the target element. When the relative distance is less than 10 mm, the automatic adsorption function is triggered, and the origin of the reference coordinate system and the origin of the target element coordinate system are calculated to coincide with each other, and the dragged element is moved to keep the two origins coincident. Furthermore, the x-axis vectors of the coordinate systems of the dragged element and the target element are determined to be consistent. If they are inconsistent, the dragged element is rotated around the coincident origin and the x-axis vectors are kept coincident. After the x-axis vectors are consistent, the y-axis vector is determined. If the y-axis is inconsistent, the dragged element is rotated around the origin and the x-axis to keep the y-axis vector coincident. According to the principle of the same spatial coordinate system, when the origin, x-axis vector, and y-axis vector of the two coordinate systems coincide, the z-axis vector is automatically in a coincident state, and only the coincidence needs to be verified.

[0036] It should be understood that when achieving automatic adsorption, the origins of the two reference coordinate systems may be aligned first, and then the axis vectors of the two reference coordinate systems may be aligned, or the axis vectors may be aligned first, and then the origins of the coordinate systems may be aligned. The order of executing the steps is not limited here.

[0037] As an optional implementation method of this embodiment, when the dragged position reaches the preset position, the dragged any three-dimensional component element and the target three-dimensional component element are automatically adsorbed, including: if any three-dimensional component element has multiple reference coordinate systems at the same junction point, detecting whether the reference coordinate system switching operation at the same junction point is triggered; if the switching operation is triggered, detecting the third reference coordinate system of the any three-dimensional component element currently at the junction point; detecting the second reference coordinate system preset at the junction point of the target three-dimensional component element; when being dragged, detecting the distance between the origin of the third reference coordinate system and the origin of the second reference coordinate system; if the distance is less than the preset threshold, aligning the third reference coordinate system and the second reference coordinate system to complete automatic adsorption.

[0038] In this optional implementation, in the coordinate system at the junction point of each three-dimensional component element, the same origin position can be preset with multiple coordinate systems with different vectors. In this case, when performing automatic adsorption, a program pop-up window can be displayed on the page to prompt the user to make a selection, and automatic adsorption is performed based on the coordinate system selected by the user. The adsorption process is the same as mentioned above and will not be repeated here.

[0039] By setting up coordinate systems with different vectors at the same origin, a variety of combinations can be achieved at a single location, rather than being limited to alignment with the same central axis as in related technologies. This allows for a diverse range of 3D model combinations.

[0040] As an optional implementation of this embodiment, after the automatic adsorption is completed or before the automatic adsorption is completed, the method further includes: if it is detected that a custom adsorption operation is triggered for any of the three-dimensional component elements, adsorbing the any three-dimensional component element and the target three-dimensional component element based on the position of the target three-dimensional component element and the custom parameters indicated by the custom adsorption operation.

[0041] In this optional implementation, if the result of automatic dynamic adsorption is not what the user needs, or custom adsorption is performed before automatic adsorption, the target three-dimensional component element coordinate system can be used to perform vector reverse adsorption and rotate a given angle around a coordinate axis to adjust the adsorption.

[0042] As an optional implementation method of this embodiment, if it is detected that any of the three-dimensional component elements is triggered by the reverse adsorption operation, the reference coordinate system preset at the combination point of the target three-dimensional component element is used as a reference to rotate the any three-dimensional component element 180° to complete the adsorption.

[0043] In this optional implementation, if the custom operation indicates reverse adsorption, reverse adsorption can be performed based on the coordinate axis selected by the user. For example, if the x-axis vector reverse fit is selected, the dragged 3D component element rotates 180 degrees around the origin and the z-axis; for example, if the y-axis vector reverse fit is selected, the dragged 3D component element rotates 180 degrees around the origin and the x-axis; for example, if the z-axis vector reverse fit is selected, the dragged 3D component element rotates 180 degrees around the origin and the x-axis.

[0044] As an optional implementation method of this embodiment, if it is detected that any of the three-dimensional component elements is triggered to be adjusted at a given angle, the reference coordinate system preset at the combination point of the target three-dimensional component element is used as a reference, and the adsorption of any of the three-dimensional component elements is completed by rotating at the given angle.

[0045] In this optional implementation, when adjusting at a given angle, it can include adjusting with x-axis rotation: the dragged three-dimensional component element rotates around the origin and the x-axis at a given angle; adjusting with y-axis rotation: the dragged element rotates around the origin and the y-axis at a given angle; adjusting with z-axis rotation: the dragged element rotates around the origin and the z-axis at a given angle.

[0046] Through customized adsorption, 3D models can be constructed in a personalized and flexible manner.

[0047] By using the above-mentioned automatic adsorption and custom adsorption methods, the combination of three-dimensional component elements is not restricted by shape and position constraints. Alignment can be achieved based on the coordinate system data at the junction point. Because the junction points are preset, the number and position of junction points can be added as needed. The flexibility of the junction points enables the three-dimensional component elements to adapt to complex and changeable combination forms, which is not possible in related technologies.

[0048] As an optional implementation of this embodiment, the method further includes: after detecting that a modification operation of the combined three-dimensional model is triggered, updating the three-dimensional component element to be modified based on the modification content indicated by the modification request.

[0049] In this optional implementation, the combined three-dimensional component model can adjust the position, modify the value, adjust the color and text direction, and show and hide the annotations of the size parameters of each three-dimensional component element that constitutes the three-dimensional component model in the 3D state. When the size parameter value is modified, the system will automatically update the corresponding 3D model and perform lightweight compression to obtain a lightweight 3D model to improve loading speed and smoothness of operation. The combined components can set different material properties for each element to obtain the corresponding display effect to achieve what you see is what you get. Materials can be called from the preset part material library, which contains data such as material type, material, surface color, surface treatment, and material ball library, such as steel, iron, copper, aluminum, plastic, etc., to achieve various display effect editing configurations of the 3D model.
