[0002] With the continuous development of computer technology, computer-aided design has been increasingly used in daily graphic design. Sketches are an important part of the design process, especially in the field of mechanical design.

[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0056] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0057] As mentioned in the background technology, see Figure 1As shown, taking the geometric object as a rectangle and the chamfer operation as a rounding operation as an example, in the related technology, after the rectangle is rounded, the two edges related to the rounding are clipped, so that the constraints based on the two edges are lost, causing the rectangle to change from a fully constrained state to an under-constrained state, that is, the constraint state of the geometric object is changed, and at the same time, the two ends of the dimension marking also move with the clipping of the edges, from 98.15 to 84.23, which makes the dimension marking of the rectangle unreasonable, and the diagram is wrong, resulting in poor design quality of the geometric object, which in turn affects the user experience.
[0058] Based on the above-mentioned defects, the present application provides a chamfer function optimization method, which determines the reference point through two target edges, provides data benchmark information for subsequent constraint replacement operations, and obtains constraint information subject to all external constraints, so as to more accurately determine the target object other than the target edge in the graphics to be processed before chamfering, so as to quickly find the missing constraints outside the chamfer, and then replace the constraints between the target object and the target edge with the constraints between the reference point and the target object, thereby automatically creating equivalent constraints corresponding to the target object according to the existing constraints, ensuring that the graphics to be processed are still in a fully constrained state after chamfering, and when the chamfering is completed, the original dimension annotation information is promptly corrected to the target dimension annotation information, so as to obtain the correct annotation, thereby improving the design quality and efficiency, and making the effect presented by the chamfering function more in line with the user's drawing habits, thereby improving the user experience.
[0059] The chamfering function optimization method provided in the embodiment of the present application can be applied to Figure 2In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be set up separately, or it can be integrated on the server 104, or it can be placed on the cloud or other servers. The terminal 102 can send the graphics to be processed in the sketch environment to the server 104. After the server 104 receives the graphics to be processed, for the graphics to be processed, two target edges to be chamfered are obtained, and the reference point is determined based on the two target edges. Then, for each target edge, the constraint information of all external constraints on the target edge at each endpoint is obtained, and the target object in the graphics to be processed is determined based on the constraint information, and then the constraint between the target object and the target edge is replaced with the constraint between the reference point and the target object. Then, when the chamfering operation is completed on the target edge, the original dimension annotation information of the target edge is corrected and processed into the target dimension annotation information, thereby providing feedback to the terminal 102. In addition, in some embodiments, the chamfer function optimization method can also be implemented independently by the server 104 or the terminal 102. For example, the terminal 102 can directly perform chamfer function optimization processing on the graphics to be processed, or the server 104 can obtain the graphics to be processed from the data storage system and perform chamfer function optimization processing on the graphics to be processed.
[0060] The terminal 102 may be, but is not limited to, various desktop computers, laptop computers, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The server 104 may be implemented as an independent server or a server cluster consisting of multiple servers, or may be a cloud server.
[0061] In an exemplary embodiment, Figure 3 As shown, a chamfer function optimization method is provided, which is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, the method is applied to Figure 2 The server 104 in the example is used as an example to illustrate the method, which includes the following steps S201 to S205. Among them:
[0062] Step S201, obtaining two target edges to be chamfered in the graphics to be processed in a sketch environment, and determining reference points based on the two target edges.
[0063] It should be noted that the graphics to be processed are graphics that need to be chamfered, and the target edges are two edges in the graphics to be processed that need to be chamfered. The chamfering may include rounding and beveling. The sketch environment refers to an environment for creating and editing graphics, such as a CAD environment or a SolidWorks environment.
[0064] Specifically, the computer device may first obtain the graphics to be processed in the sketch environment, and determine two target edges to be chamfered in the graphics to be processed. For example, when the graphics to be processed is a rectangle, the two target edges may be a long edge and an adjacent short edge. After determining the two target edges to be chamfered, a reference point may be determined based on the two target edges. The reference point is a data reference point for subsequent constraint supplementation.
[0065] In this embodiment, in the process of determining the reference point based on the two target edges, the endpoint coordinates and original size information of the two target edges can be first obtained, and the intersection of the two target edges can be calculated based on the endpoint coordinates and the original size annotation information, and then the intersection is used as the reference point.
[0066] For example, taking the figure to be processed as a rectangle as an example, see Figure 4 As shown, Figure 4 The schematic diagram of the structure for creating a reference point shows that the two target edges to be chamfered in the figure to be processed are A and B. The figure above is a diagram of the figure to be processed before chamfering, and the figure below is a diagram of the figure to be processed after chamfering. By obtaining the coordinates of the two endpoints of the target edge A and the target edge B and their respective original dimensioning information, the intersection of the two target edges is calculated and a real point C is created at the intersection, which is used as the reference point.
[0067] In this embodiment, two target edges to be chamfered in the graphics to be processed in the sketch environment are obtained, and reference points are determined based on the two target edges, so as to accurately determine the reference points for subsequent constraints, thereby facilitating subsequent constraint replacement operations.
[0068] Step S202: for each target edge, obtain constraint information of all external constraints on the target edge at each endpoint; the constraint information includes: the number of constraints, constraint objects, and constraint categories.
[0069] Specifically, after obtaining two target edges, constraint supplementation may be performed on each target edge, and constraint information may be obtained for each target edge, for example, constraint information of all external constraints imposed on the target edge at each endpoint may be obtained.
[0070] It should be noted that the above number of constraints refers to the total number of constraints directly associated with the target edge. For example, if there is a vertical constraint and a horizontal constraint at each end of the target edge, the number of constraints for this line segment is 2. The constraint object may be a line segment, a point, etc. The constraint category refers to the specific type of constraint. Common constraint categories include but are not limited to: geometric constraints, dimensional constraints, and position constraints. Geometric constraints can include parallel, vertical, concentric, and collinear, etc.; dimensional constraints can include fixed length, fixed angle, fixed radius, etc.; position constraints include fixed points, symmetry, etc.
[0071] As an optional implementation, in the process of obtaining constraint information, the user can click a preset control in the sketch environment, and display it through the status bar, property window or pop-up information box, so as to obtain the constraint information of all external constraints on the target edge at each endpoint. As another optional implementation, the constraint information can be imported from an external device or obtained by real-time detection.
[0072] For example, taking the two target edges as straight line A and straight line B, for the first target edge straight line A, the two endpoints of the first target edge straight line A can be determined first, and then by calling the preset interface, the input of the preset interface is set as the two endpoints of the first target edge A, and the output is the number of constraints, constraint objects and constraint list of the two endpoints of the first target edge straight line A.
[0073] Step S203, determining the target object in the to-be-processed graphic according to the constraint information; the target object is the geometric object except the target edge before the chamfering process.
[0074] It is understandable that the target object is a geometric object other than the target edge in the graphics to be processed before chamfering. After obtaining the constraint information of the target edge, the graphics to be processed can be analyzed according to the constraint type, constraint object and constraint number, so as to determine the target object in the graphics to be processed.
[0075] Alternatively, if Figure 5 As shown, the above step S203 is replaced by the following steps S301 to S304:
[0076] Step S301, judging whether the external constraint belongs to a preset constraint category according to the constraint category, the preset constraint category includes at least one of the following: coincidence constraint, point-on-line constraint, horizontal alignment constraint, vertical alignment constraint, intersection constraint.
[0077] Step S302: when it belongs to a preset constraint category, obtain a geometric object related to the constraint category.
[0078] Step S303, comparing the geometric object with the target edge to obtain a comparison result; the comparison result is used to indicate whether the geometric object is consistent with the target edge.
[0079] Step S304: when the comparison result indicates that the geometric object is inconsistent with the target edge, the geometric object with inconsistent comparison is determined as the target object.
[0080] Specifically, for each target edge, after obtaining the constraint category, it can be determined whether the external constraint belongs to one of the coincidence constraint, point-on-line constraint, horizontal alignment constraint, vertical alignment constraint or intersection constraint according to the constraint category. When it belongs to the preset constraint category, the geometric object related to the constraint category is obtained.
[0081] It can be understood that the point-on-line constraint, horizontal alignment constraint, vertical alignment constraint, and intersection constraint are additional constraints parallel to the coincidence constraint. Among them, each constraint category corresponds to an application scenario. For the coincidence constraint, for example, a coincidence constraint is created between the starting point of line A and the starting point of line B. Then, no matter how lines A and B are dragged in the software view interface, the starting point of line A and the starting point of line B always remain coincident; for the horizontal alignment constraint, for example, a horizontal alignment constraint is created between the starting point of line A and the starting point of line B. Then, no matter how lines A and B are dragged in the software view interface, the starting point of line A and the starting point of line B always remain horizontally aligned. For the vertical alignment constraint, for example, a vertical alignment constraint is created between the starting point of line A and the starting point of line B. Then, no matter how lines A and B are dragged in the software view interface, the starting point of line A and the starting point of line B always remain vertically aligned. For the point-up constraint, for example, a point-on-line constraint is created between the starting point C of line A and line B. Then, no matter how lines A and B are dragged in the software view interface, the starting point C of line A always moves on line B.
[0082] Exemplarily, when the external constraint belongs to a preset constraint category, a geometric object related to the constraint category is obtained, where the geometric object refers to the object constrained by the constraint object. Assuming that there is a coincidence constraint of a preset constraint category between the starting point of straight line A and the end point of another straight line B, the constraint object of the coincidence constraint to which straight line A is subject can be obtained through the interface, and the two geometric objects of this constraint can be determined from the constraint object of the coincidence constraint as the starting point of straight line A and the end point of straight line B.
[0083] It is understandable that because the premise of constraint supplementation is that the constraints outside the chamfer are lost, it is necessary to determine the geometric objects other than the target edges in the graphics to be processed, which may include one or more geometric objects. After obtaining the geometric objects related to the constraint category, it is necessary to exclude the geometric objects themselves, that is, the two target edges related to the chamfering process. The first geometric object can be used as the current geometric object, and then the obtained current geometric object is compared with the target edges related to the chamfering process. If the current geometric object is consistent with any one of the two target edges, the current geometric object is skipped, and the next geometric object is judged, and it is further compared with the target edge to obtain the comparison result. The geometric object with inconsistent comparison is determined as the target object, thereby traversing all geometric objects, and then determining all target objects from the geometric objects.
[0084] In this embodiment, it is determined whether the external constraint belongs to the preset constraint category based on the constraint category. When it belongs to the preset constraint category, the relevant geometric object is obtained, and the geometric object is compared with the target edge, so as to quickly and accurately find the target object outside the chamfer's own target edge, which is convenient for subsequent corresponding constraint replacement.
[0085] Step S204: Replace the constraint between the target object and the target edge with the constraint between the reference point and the target object.
[0086] Specifically, after obtaining the target object, the location where the constraint corresponding to the target object occurs can be found, and it can be determined whether the location where the constraint corresponding to the target object occurs coincides with the chamfer position in the graphics to be processed. If they coincide, the constraint between the target object and the target edge is replaced with the constraint between the reference point and the target object. If they do not coincide, it is marked that the current endpoint of the current target edge does not have a chamfer operation, that is, the current endpoint is not a point of interest and can be ignored.
[0087] It should be noted that in the software system environment, there is no separate point object. A point is represented by a structure of a straight line + index. For example, straight line A + index0 represents the starting point of straight line A, and straight line A + index1 represents the end point of straight line A. In the above steps, the target object other than the two chamfer-related edges in the graphics to be processed has been found. The target object can be understood as a structure. Through this structure, not only the geometric object straight line A can be obtained, but also which specific endpoint of straight line A is subject to the constraint, and the coordinate position of the endpoint of the constrained straight line A can be obtained. Then, the coordinates of the endpoint of this straight line A and the coordinates of the reference points of the two target edges related to the chamfer are compared. When the comparison is consistent, it indicates that a chamfer operation has occurred on this endpoint of the current straight line A; when the comparison is inconsistent, it indicates that no chamfer operation has occurred on this endpoint of the current straight line A.
[0088] The geometric object may include multiple endpoints. The first endpoint is determined and used as the current endpoint. When the coordinates of the current endpoint and the reference point are compared and consistent, it indicates that the current endpoint coincides with the reference point and a chamfering operation has occurred. When the comparison is inconsistent, it indicates that the current endpoint does not coincide with the reference point and no chamfering operation has occurred. Then, the next endpoint is compared, so that when the position where the corresponding constraint of the target object occurs coincides with the chamfering position in the graphics to be processed, the constraint between the target object and the target edge is replaced with the constraint between the reference point and the target object.
[0089] Exemplarily, taking the case where two target edges are straight line A and straight line B, the intersection point between the two target edges is reference point C, and the target object is D, when it is determined that the position where the constraint corresponding to straight line A occurs coincides with the chamfer position in the graphics to be processed, the constraint between straight line A and target object D is replaced with the constraint between straight line A and reference point C. By replacing the constraint between straight line A and target object D with the constraint between straight line A and reference point C, even if straight line A is clipped after the chamfering process, resulting in the disappearance of the original constraint between target object D and straight line A, since a new constraint between straight line A and reference point C is created, it is possible to ensure that the graphics to be processed after the chamfering process is still in a fully constrained state.
[0090] In this embodiment, by replacing the constraint between the target object and the target edge with the reference point and the target object, a new constraint relationship can be created to equivalently replace the constraint relationship before the chamfering process, so that the constraint relationship of the processed graphics before and after the chamfering process remains unchanged and is still in a fully constrained state.
[0091] Step S205: After the chamfering operation is completed on the two target edges, the original dimensioning information of each target edge is corrected and processed into the target dimensioning information.
[0092] It should be noted that the original dimensioning information refers to the dimensioning information corresponding to the two target edges in the graphics to be processed when it is in an under-constrained state after chamfering, and the target dimensioning information refers to the dimensioning information corresponding to the two target edges in the graphics to be processed after chamfering.
[0093] After performing the chamfering operation on the two target edges, it can be checked whether there is original dimensioning information on each target edge. When the original dimensioning information exists, the original dimensioning information can be corrected to obtain the target dimensioning information; when the original dimensioning information does not exist, it is not processed.
[0094] The chamfering function optimization method provided in the embodiment of the present application obtains two target edges to be chamfered in the graphics to be processed in a sketch environment, and determines the reference point based on the two target edges. For each target edge, the constraint information of all external constraints imposed on the target edge at each endpoint is obtained, and then the target object in the graphics to be processed is determined based on the constraint information, and the constraint between the target object and the target edge is replaced with the constraint between the reference point and the target object. After the chamfering operation is completed on the two target edges, the original dimension annotation information of each target edge is corrected and processed into the target dimension annotation information. Compared with the prior art, this technical solution determines the reference point through two target edges, provides data reference information for subsequent constraint replacement operations, and obtains constraint information subject to all external constraints, thereby more accurately determining the target object other than the target edge in the graphics to be processed before chamfering, so as to find the missing constraints outside the chamfer, and then replace the constraint between the target object and the target edge with the constraint between the reference point and the target object, thereby automatically creating equivalent constraints corresponding to the target object according to the existing constraints, ensuring that the graphics to be processed are still in a fully constrained state after chamfering, and when the chamfering is completed, the original dimension annotation information is promptly corrected to the target dimension annotation information, so as to obtain correct annotation, thereby improving the design quality and efficiency, and making the effect presented by the chamfering function more in line with the user's drawing habits, thereby improving the user experience.
[0095] In another exemplary embodiment of the present application, in order to accurately annotate the graphics to be processed and improve the design quality and efficiency, the original dimension annotation information of each target edge can be corrected and processed into the target dimension annotation information, such as Figure 6 As shown, the above step S205 is replaced by the following steps S401 to S404:
[0096] Step S401: Create an intersection constraint between two target edges and a reference point.
[0097] Step S402: for each target edge, determine whether there is original dimensioning information.
[0098] Step S403, when the original dimensioning information exists, the original dimensioning information is deleted and the target endpoint of the target edge is determined; the target endpoint is the endpoint of the target edge where no clipping operation occurs.
[0099] Step S404: Create target dimensioning information according to the target endpoint and the reference point.
[0100] Specifically, after replacing the constraint between the target object and the target edge with the constraint between the reference point and the target object, and performing a chamfering operation on the two target edges, when the chamfering operation is completed, you can find "constraint" or "relationship" related tools in the drawing software, and then select the two target edges to which the constraint needs to be applied, and select the point as the reference point. Then, in the interface of the drawing software, a context menu may appear on the interface, which may include various options of the constraint category that needs to be selected, and select the "intersect" option from the menu to add it between the two target edges and the reference point, thereby completing the creation of the intersection constraint.
[0101] After the intersection constraint between the two target edges and the reference point is created, it can be determined for each target edge whether there is original dimension annotation information. When the original dimension annotation information does not exist, it is not processed; when the original dimension annotation information exists, the original dimension annotation information is deleted and the target endpoint of the target edge is determined. By obtaining the endpoint coordinates of each endpoint of the target edge and comparing the endpoint coordinates with the reference point coordinates, the endpoint corresponding to the endpoint coordinates that are consistent with the comparison is determined as the endpoint where the clipping operation occurs, and the endpoint other than the endpoint where the clipping operation occurs is determined as the target endpoint.
[0102] For example, see Figure 7 and Figure 8 As shown, Figure 7 The schematic diagram of the rounding process is shown in Figure 2. Figure 8 Schematic diagram of the structure of the chamfer processing process. Take the two target edges including straight line A and straight line B, and the reference point C as an example. For the first target edge straight line A, first determine whether straight line A has original dimensioning information, which can be 98.12. When straight line A does not have original dimensioning information, it is not processed; when straight line A has original dimensioning information, the target endpoint of the clipping operation of straight line A is determined, by first calculating the starting point coordinates and the end point coordinates of straight line A, and then comparing the starting point coordinates and the end point coordinates of straight line A with the reference point coordinates of reference point C respectively. If the starting point coordinates of straight line A are the same as the reference point coordinates, it indicates that the starting point coordinates of straight line A have undergone a chamfer clipping operation; if the end point coordinates of straight line A are the same as the reference point coordinates, it indicates that the end point coordinates of straight line A have undergone a chamfer clipping operation.
[0103] Optionally, when the starting point coordinates of straight line A have undergone a chamfering operation, the end point coordinates of straight line A that do not undergo a chamfering operation can be used to determine the end point corresponding to the end point coordinates of straight line A as the target endpoint of straight line A; when the end point coordinates of straight line A have undergone a chamfering operation, the starting point coordinates of straight line A that do not undergo a chamfering operation can be used to determine the end point corresponding to the starting point coordinates of straight line A as the target endpoint.
[0104] When the target endpoint is determined, the target endpoint coordinates corresponding to the target endpoint and the reference point coordinates corresponding to the reference point C are determined, and the first distance between the two is calculated based on the target endpoint coordinates and the reference point coordinates. The first distance is used as the target dimension annotation information of the straight line A, and the target dimension annotation information can be 121.24.
[0105] Similarly, for the second target edge straight line B, first determine whether there is original dimension annotation information for straight line B. When there is original dimension annotation information for straight line B, delete the original dimension annotation information and determine the target endpoint of straight line B in the same way as the above straight line A. Then, based on the target endpoint coordinates of the target endpoint of straight line B and the reference point coordinates of reference point C, calculate the second distance between the two, and use the second distance as the target dimension annotation information for straight line B.
[0106] In this embodiment, an intersection constraint is created between two target edges and a reference point, and for each target edge, it is determined whether there is original dimension annotation information, so as to determine whether correction processing is required based on the result, and then the target endpoint of the target edge is determined, and then the target dimension annotation information is accurately created based on the target endpoint and the reference point, thereby improving the design quality and efficiency, making the effect presented by the chamfering function more in line with the user's drawing habits, and thus improving the user experience.
[0107] The present application also provides an application scenario, which applies the above-mentioned chamfering function optimization method. Specifically: The chamfering function optimization method provided in this embodiment can be applied in a picture drawing scene in a sketch environment. The computer device obtains two target edges to be chamfered in the graphics to be processed in a color image environment, and determines the reference point based on the two target edges, and then obtains the constraint information of the target edge at each endpoint, and determines the target object in the graphics to be processed according to the constraint information, and replaces the constraint between the target object and the target edge with the constraint between the reference point and the target object, and then after the chamfering operation is completed on the two target edges, the original dimension annotation information of each target edge is corrected and processed into the target dimension annotation information. The chamfering function optimization method provided in this embodiment may include a chamfering processing link or a chamfering processing link for the graphics, and can automatically calculate the appropriate fillet radius and bevel parameters according to the existing constraints, thereby reducing user participation and improving design quality and efficiency.
[0108] Based on the same inventive concept, the embodiment of the present application also provides a chamfering function optimization device for implementing the chamfering function optimization method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more chamfering function optimization device embodiments provided below can refer to the limitations of the chamfering function optimization method above, and will not be repeated here.

[0112] The object determination module 730 is used to determine the target object in the graphics to be processed according to the constraint information; the target object is the geometric object other than the target edge before the fillet processing;
[0113] A constraint replacement module 740, for replacing the constraint between the target object and the target edge with the constraint between the reference point and the target object;
[0114] The annotation correction module 750 is used to correct the original dimension annotation information of each target edge into the target dimension annotation information after the chamfering operation is completed on the two target edges.
[0115] As an optional implementation, the object determination module 730 is specifically configured to:
[0116] Determining whether the external constraint belongs to a preset constraint category according to the constraint category, where the preset constraint category includes at least one of the following: coincidence constraint, point-on-line constraint, horizontal alignment constraint, vertical alignment constraint, and intersection constraint;
[0117] When it belongs to the preset constraint category, obtain the geometric object related to the constraint category;
[0118] Compare the geometric object with the target edge to obtain a comparison result; the comparison result is used to indicate whether the geometric object is consistent with the target edge;
[0119] When the comparison result represents that the geometric object is inconsistent with the target edge, the geometric object with inconsistent comparison is determined as the target object.
[0120] As an optional implementation, the constraint replacement module 740 is specifically configured to:
[0121] Find the location where the corresponding constraint of the target object occurs;
[0122] Determine whether the position where the corresponding constraint of the target object occurs coincides with the chamfer position in the graphics to be processed;
[0123] If they are coincident, the constraint between the target object and the target edge is replaced by the constraint between the reference point and the target object.
[0124] As an optional implementation, the annotation correction module 750 is specifically configured to:
[0125] Create an intersection constraint between the two target edges and the reference point;
[0126] For each target edge, determine whether there is original dimensioning information;

[0128] Create target dimensioning information based on the target endpoint and reference point.

[0137] Among them, by implementing this implementation method, the chamfering function optimization device determines the reference point through two target edges, provides data reference information for subsequent constraint replacement operations, and obtains constraint information subject to all external constraints, thereby more accurately determining the target object other than the target edge in the graphics to be processed before chamfering, so as to find the missing constraints outside the chamfer, and then replace the constraint between the target object and the target edge with the constraint between the reference point and the target object, thereby automatically creating equivalent constraints corresponding to the target object according to the existing constraints, ensuring that the graphics to be processed are still in a fully constrained state after chamfering, and when the chamfering is completed, timely correcting the original dimension annotation information to the target dimension annotation information, thereby obtaining correct annotation, improving design quality and efficiency, and making the effect presented by the chamfering function more in line with the user's drawing habits, thereby improving user experience.
