[0030] Embodiment 1

[0031] Figure 1 A flowchart of a drawing generation method is provided for the first embodiment of the present invention. This embodiment is applicable to vehicle equipment, such as the generation of assembly drawings of all-aluminum low-temperature radiators. The method can be executed by a drawing generation device, which can be implemented in the form of hardware and / or software, and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0032] S110. In response to the received assembly drawing generation instruction, a geometric graphics set is obtained, a target view direction is determined, and a target view set corresponding to the target view direction is searched in the geometric graphics set.

[0033] Among them, the geometry set can be understood as a collection of geometric figures with different view directions and dimensions. The geometric figures can be two-dimensional figures (such as circles, triangles, and polygons) or three-dimensional figures (such as cubes, spheres, and cylinders). The view set can be understood as a class for storing processing methods for generating the same view. The view direction can be understood as the direction of viewing the view, and the view direction can include at least one of the front view, top view, and side view.

[0034] Specifically, in response to the received assembly drawing generation instruction, a set of multiple geometric figures or a set of multiple geometric figures pre-generated by a graphics generation algorithm is obtained from a database, at least one target view direction is determined, and a target view set corresponding to each target view direction is searched in the geometric figure set.

[0035] Optionally, before obtaining the geometric graphics set, the method further includes: constructing a three-dimensional part digital model based on a pre-constructed part database and manually input part parameter values, wherein the three-dimensional part digital model stores a parameter selection-part type comparison table, a skeleton-part relationship comparison table and at least one geometric graphics set;

[0036] Specifically, by locating the location of the parts database in the package configuration file, copy the database to the path specified when creating a new project, rename the folder and its internal data, and then open the skeleton data. After manually entering the parameter value in the interface for confirmation, the system assembles the axis position and parameter value information of each parameter according to the skeleton data on the structure tree, quickly generates the digital model by unifying the parameter values ​​of the same-name parameters in the digital model of the required parts, and quickly instantiates and assembles the parts according to the parameter selection-part type, skeleton-part relationship comparison table.

[0037] Among them, skeleton data can be understood as the data of the internal structure and key supporting elements of the part. Skeleton data can include information such as the part's geometry, size, material properties, connection methods, and key supporting points.

[0038] The step of obtaining a geometric figure set includes: obtaining a geometric figure set from the three-dimensional part digital model.

[0039] In the embodiment of the present invention, by directly acquiring the geometric graphics set from the pre-established three-dimensional part digital model, the efficiency of acquiring the collective graphics set is greatly improved.

[0040] Optionally, the method also includes: when updating the three-dimensional part digital model, determining the part parameters to be changed and searching for a parameter set to be changed that includes the part parameters to be changed; and updating the three-dimensional part digital model by changing the part parameters to be changed and the parameters under the parameter set to be changed.

[0041] Specifically, when updating the three-dimensional part digital model, at least one part whose parameters need to be changed is selected, the parameters of the part to be changed are determined, and the parameter set to be changed that contains the parameters of the part to be changed is searched. After selecting the parameters under the parameter set to be changed, the three-dimensional part digital model is updated by assigning new parameter values ​​to the parameters of the part to be changed and the parameters under the parameter set to be changed. Among them, the parameter set to be changed that is the same as the identifier of the part parameter to be changed can be searched based on the identifier of the part parameter to be changed. It is also possible to search for the parameter set to be changed that has a pre-established association relationship with the part parameter to be changed.

[0042] Optionally, the method also includes: in response to a part replacement request for the three-dimensional part digital model, searching for a target geometric set matching the part to be replaced in the skeleton data of the first storage space according to the identification of the part to be replaced; and completing the part replacement by replacing the coordinate axes of the part to be replaced with the coordinate axes in the target geometric set and matching them with the coordinate axes in the skeleton of the part to be replaced.

[0043] The first storage space stores skeleton data of multiple parts.

[0044] Exemplarily, based on the part to be replaced selected by the user, determine whether it is a file of a preset file type. If so, traverse the geometric graphics set in the assembly, search for a target geometric graphics set that matches the part to be replaced in the skeleton data of the first storage space according to the identifier of the part to be replaced, search for a defined coordinate axis in the target geometric graphics set, replace the coordinate axis of the part to be replaced with the coordinate axis in the skeleton of the part to be replaced. If the file currently being processed is not of a preset file type or the target geometric graphics set is not found, check whether a coordinate axis with a preset identifier has been published in the part, read the position and direction information of the coordinate axis with the preset identifier, and align the coordinate axis with the coordinate axis in the skeleton to achieve the same position and direction as the skeleton coordinate axis.

[0045] In the embodiment of the present invention, the parts to be replaced are replaced by searching for matching graphic sets or coordinate axes with preset identifiers, thereby improving the efficiency of parts replacement.

[0046] S120. Read the graphic elements and graphic element attribute information in the target view set, and output the graphic elements as view annotation information based on the graphic element attribute information, wherein the graphic element attribute information includes multiple types of dimension annotation information, benchmark standard information and annotation annotation information.

[0047] Among them, graphic elements include point elements, line elements and surface elements, etc. All graphic elements need to be loaded and read from the target view set. Graphic element attribute information includes position attribute information, length attribute information, color attribute information and width attribute information.

[0048] Optionally, each graphic element has a graphic element identifier, which includes the position and size information of the element in the view. The graphic element can be output as view annotation information according to the graphic element identifier.

[0049] Specifically, all graphic elements are loaded and read from the target view set. Each graphic element has its position and size information in the view. Graphic element attribute information of the graphic element is parsed, and based on the parsed graphic element attribute information and according to the graphic element identifier, the graphic element is output as multiple types of dimensioning information, benchmark standard information and annotation information.

[0050] Optionally, the target view set includes a skeleton view set, and the graphic element attribute information includes skeleton element attribute information; accordingly, reading the graphic elements and graphic element attribute information in the target view set, and outputting the graphic elements as view annotation information based on the graphic element attribute information, includes: reading the point elements, line elements and the skeleton element attribute information in the skeleton view set, and outputting the point elements and the line elements as different types of skeleton dimension annotation information and skeleton reference annotation information based on the skeleton element attribute information, wherein the skeleton view set is used to store the graphic elements for constructing a sub-view framework, and the point elements and line elements in the skeleton view set are used to map to the sub-view based on preset mapping rules to annotate the sub-view framework.

[0051] Specifically, the view direction is determined by the direction of the three coordinate axes, the point elements and line elements in the skeleton view set corresponding to the view direction are read, and the point elements and line elements are output as different types of skeleton dimension annotation information and skeleton reference annotation information based on the skeleton element attribute information.

[0052] Optionally, the target view set includes a part graphics set, and the graphic element attribute information includes skeleton element attribute information; accordingly, reading the graphic elements and graphic element attribute information in the target view set, and outputting the graphic elements as view annotation information based on the graphic element attribute information, includes: reading the point elements, line elements and part element attribute information in the part graphics set, and outputting the point elements and the line elements as different types of part dimension annotation information based on the part element attribute information, wherein the part graphics set is used to store graphic elements for constructing sub-view parts, and the point elements and line elements in the part graphics set are used to map to the sub-view based on preset mapping rules to annotate the parts of the sub-view.

[0053] In the embodiment of the present invention, the skeleton and part annotation information of the sub-view are obtained based on the graphic elements in the skeleton view set and the part graphic set, respectively, so as to facilitate the rapid construction of sub-views in multiple viewing directions.

[0054] S130. Annotate the view annotation information to the view corresponding to it to obtain at least one sub-view, and integrate at least one of the sub-views into the drawing to generate the assembly drawing.

[0055] Specifically, the view annotation information is respectively annotated to the corresponding views to obtain at least one sub-view, and the sub-views in multiple directions are integrated into the drawing to generate the assembly drawing.

[0056] In the embodiment of the present invention, the efficiency of sub-view annotation is improved, errors caused by manual annotation are avoided, and the automation level of sub-view construction is improved.

[0057] Optionally, after generating the assembly drawing, the method further includes:

[0059] The associated parameters can be understood as parameters that are associated with the parameters in the three-dimensional part digital model, for example, parameters with the same identifier.

[0060] Specifically, the update of the assembly drawing is achieved by checking the parameter values ​​in the 3D part digital model and assigning them to the associated parameters in the 2D assembly drawing file.

At least one of the subviews is placed in the target position in the drawing in sequence according to the preset layout rules, and the subviews are adjusted during the placement process to ensure that all subviews comply with the layout rules and the relationship between each other is clear. After all subviews are placed, final adjustments and optimizations are made to obtain the target view. For example: check the spacing and alignment between subviews of the annotation information, optimize the overall layout of the drawing, etc.
