It should be noted that, the execution body of the method embodiment described below may be a connection piece placement or adjacency determination device, and the device may be implemented in a manner of software, hardware, or a combination of software and hardware, to be part or all of the computer device described above. The following method embodiments are described taking an execution subject as a computer device as an example.
Fig. 2 is a flow chart of a method for placing a connecting piece according to an embodiment. The embodiment relates to a specific process that computer equipment automatically sets connecting pieces between entity models to be connected. As shown in fig. 2, the method includes:
S11, screening a model to be connected from a model group according to model attribute information of the entity model; the model attribute information is used for representing whether the entity models are connected by adopting a connecting piece or not.
It should be noted that the model set is a large model, which may represent a building, a space inside a building, or a system of a building, such as a steel structure system, a pipeline system, etc. The solid model may be a subelement that constitutes the model set; in addition, the entity model can represent an entity in an actual building, such as a column of a cold-formed thin-wall light steel structure of the building. The model attribute information may include an identifier of the entity model, for example, a name, a code number, or a category, and may further include a label that whether the entity model and other entity models need to be connected by using a connector; optionally, the method further includes a tag of a type of a connection element used by the entity model in connection, which is not limited in this embodiment, and the model attribute information only needs to represent whether the entity models need to be connected by using the connection element.
Specifically, because the model attribute information can represent whether the entity models are connected by adopting the connecting piece, the computer equipment can screen the model to be connected, which is required to be connected by adopting the connecting piece, from the model group according to the model attribute information of each entity model in the model group.
S12, determining adjacent surfaces with adjacent relations on different models to be connected by adopting a preset adjacent algorithm according to the model surface information of each model to be connected; the adjacency algorithm is an algorithm for determining the adjacency relation between model surfaces according to the intersecting state after the model surfaces are extended.
It should be noted that each model to be connected may have a plurality of surfaces, each surface being characterized by corresponding model surface information. Alternatively, the model surface information may include, but is not limited to, the size, position, normal, etc. of each surface of the solid model. Specifically, the computer device adopts a preset adjacent algorithm, that is, each surface extends according to the model surface information of each model to be connected, and judges the adjacent relation between the models according to the intersecting state between the extended surface and other models, so as to generate an adjacent surface with the adjacent relation, and optionally, an adjacent model with the adjacent relation can also be generated. For example, if after extension intersects a surface, the computer device may determine that both are adjacent surfaces; if after extension it does not intersect a surface, it can be judged that both are not adjacent surfaces. Wherein each group of adjacent surfaces comprises two surfaces with adjacent relation, and the two surfaces are respectively positioned on different models to be connected.
S13, placing connecting pieces between the adjacent faces according to a preset connecting piece generation rule.
It should be noted that the rule for generating the connection piece may include a rule such as a distance between the connection pieces, a distance between two end points and other solid models, and optionally, a rule for reinforcing the connection pieces at two ends of the model to be connected, which is not limited in this implementation. The above-mentioned connector generation rule needs to meet the design standard of the connector in national standard and line standard; optionally, the connector design criteria in the enterprise criteria may also be met.
Specifically, the computer device may place the corresponding connection element on each determined set of adjacent surfaces according to the connection element generation rule. For example, taking a combined upright as an example, in the determined combined upright of two cold-formed thin-wall light steel structures, if the computer equipment is determined that the A face of the upright 1 and the A face of the upright 2 are adjacent faces, the computer equipment uniformly generates connecting pieces on the adjacent faces according to a specified interval, for example, an interval of 3 meters; optionally, it may also be checked whether the distance between the nearest connector at the two ends of the combined upright and the end point meets the design criteria, and if not, the adjustment is automatically performed according to the design criteria, or based on manual adjustment operations of the designer.
In this embodiment, since the model attribute information can characterize whether the entity models need to be connected by using the connecting piece, the computer device can automatically screen the model to be connected from the model group according to the model attribute information of the entity models, thereby screening out the entity models which do not need to be connected, reducing a large number of subsequent invalid calculations, making the pertinence of subsequent operations stronger, and the generating efficiency higher and more accurate.
In addition, the computer equipment automatically determines adjacent surfaces with adjacent relations on different models to be connected by adopting a preset adjacent algorithm according to the model surface information of each model to be connected, and further automatically determines the models to be connected which need to be connected, so that the problems of misjudgment and omission possibly caused by manually and subjectively judging the adjacent surfaces are avoided, and the adjacent surfaces determined by the method are high in efficiency and high in accuracy. Moreover, the adjacent algorithm is an algorithm for determining the adjacent relation according to the intersecting state after the model surface is extended, so that the adjacent relation is judged and converted into the intersecting relation, and the method is easier to realize in computer software and has high accuracy. Finally, the computer equipment automatically generates the connecting piece between the adjacent surfaces according to a preset connecting piece generation rule, so that the automatic generation of the connecting piece between the models to be connected is completed, a designer is not required to manually place the connecting piece, the problems of human operation errors and low efficiency are avoided, and the generating efficiency and the accuracy of the connecting piece are improved. The method provided by the embodiment can automatically place the connecting piece through the computer equipment, so that the problems of errors and low efficiency possibly caused by manual design of a designer are avoided.
Optionally, on the basis of the embodiment shown in fig. 2, the model attribute information includes a model identifier, and a correspondence relationship exists between the model identifier and the connection attribute. Specifically, the model attribute information may include a model identifier of the entity model, for example, a name, a serial number, an ID, or a category of the entity model. The model identifier of the entity model has a corresponding relation with the connection attribute, and the connection relation can comprise an attribute of whether connection is needed or not or an attribute of what kind of connection piece is needed to be used for connection. For example, the model name is 'columns of cold-formed thin-walled light steel structures', which correspond to the connection properties required for connection, and optionally also to flat steel strip connectors. In this embodiment, since the model attribute information includes the model identifier and the corresponding relationship exists between the model identifier and the connection attribute, the computer device can screen the model to be connected from the multiple entity models of the model group through the model attribute information.
Optionally, on the basis of the foregoing embodiment, a possible implementation manner of S12 may further be as shown in fig. 3, including:
S121, generating corresponding virtual entities along the normal direction of each model surface; the size of the virtual entity is the same as that of the corresponding model surface, and the thickness of the virtual entity is used for representing the judgment threshold value of the adjacent relation.
In particular, the computer device may generate a virtual entity corresponding to each model surface along a normal direction to the model surface. The virtual entity and the corresponding model surface are the same in size and shape. The virtual entity has a thickness, and the setting of the thickness can be a judging threshold value of the adjacent relation. For example, if setting the distance between two objects to be less than or equal to 3 mm can be considered to be adjacent, the thickness of the virtual entity can be set to 3 mm; if the distance between two objects is greater than 3 mm, then it is considered that the two are not adjacent. Alternatively, the virtual entity may be transparent in the model set, and have properties (such as intersection, collision, etc.) of the entity model, while not affecting the presentation of other entity models.
S122, acquiring an intersecting state between the virtual entity and the surface of the model to be judged; the model surface to be judged is the model surface of other models to be connected, and the other models to be connected are entity models except the models to be connected corresponding to the virtual entity.
Specifically, the computer device may determine whether the virtual entities intersect with the model surfaces to be determined, thereby obtaining an intersection state between each virtual entity and each model surface to be determined. The intersection status may include intersecting or non-intersecting. It should be noted that the model surface to be determined is a model surface of another model to be connected except the model to be connected to which the virtual entity belongs. Each virtual entity does not need to judge the intersecting state with the model to be connected to which the virtual entity belongs.
S123, determining the adjacent surface according to the intersecting state between the virtual entity and the surface of the model to be judged.
Specifically, the computer device determines an adjacent surface having an adjacent relationship according to the intersecting state between the virtual entity and the surface of the model to be judged.
Alternatively, one possible implementation of this step may include: if the virtual entity intersects with the model surface to be judged, determining the model surface corresponding to the virtual entity and the model surface to be judged as the adjacent surfaces; and if the virtual entity is not intersected with the surface of the model to be judged, determining that the surface of the model corresponding to the virtual entity and the surface of the model to be judged are not adjacent surfaces. Specifically, if the virtual entity intersects with the surface of the model to be judged, determining that the surface of the model corresponding to the virtual entity and the surface of the model to be judged are adjacent surfaces; otherwise, if the virtual entity does not intersect with the surface of the model to be judged, it is determined that the surface of the model corresponding to the virtual entity is not adjacent to the surface of the model to be judged and does not belong to an adjacent surface. In the implementation manner, the computer equipment determines that the model surface corresponding to the virtual entity and the model surface to be judged are adjacent surfaces and not adjacent surfaces respectively when the virtual entity and the model surface to be judged are intersected and not intersected respectively, so that adjacent surfaces with adjacent relation can be accurately determined in a plurality of model surfaces, and the method is easy to realize and high in accuracy.
In this embodiment, the computer device generates a corresponding virtual entity along the normal direction of each model surface, and because the size of the virtual entity is the same as that of the corresponding model surface, the thickness of the virtual entity is used to represent the judgment threshold of the adjacent relationship, so that the computer device can obtain the intersection state between the virtual entity and the model surface to be judged, and then determine the adjacent surface with the adjacent relationship according to the intersection state between the virtual entity and the model surface to be judged.
Alternatively, on the basis of the foregoing embodiments, one possible implementation manner of the foregoing S13 may include: determining the generation position of the connecting piece on the adjacent surface according to the generation rule; the connector is deployed in the generating position. It should be noted that, each solid model may be expanded in the model group according to its own coordinate system by a reference point or a reference line, so as to implement placement of the solid model. Thus, the computer device may determine the generation position of the connection piece on the adjacent surface according to the generation rule, the generation position may be the position of the reference point of the connection piece or the position of the reference line, and then the computer device expands the connection piece on the generation position according to the self coordinate system of the connection piece, thereby completing the automatic placement of the connection piece. Optionally, the specific description of the above generation rule may be referred to the description in the embodiment of fig. 2, which is not repeated here. In this embodiment, the computer device determines the generating position of the connecting piece on the adjacent surface according to the generating rule, and expands the connecting piece on the generating position, thereby completing automatic placement of the connecting piece, avoiding the problems of errors and low efficiency possibly caused by manual placement, and improving the placement efficiency and accuracy of the connecting piece.
The foregoing embodiments describe in detail how the computer device automatically places the connector based on the adjacent face, and how the computer device automatically recognizes the adjacent face based on the information of the solid model will be described below.
Fig. 4 is a flowchart of a method for determining an adjacency according to an embodiment. The present embodiment relates to a specific process in which a computer device automatically determines an adjacency based on model surface information. As shown in fig. 4, includes:
s21, obtaining model surface information of the target entity model.
It should be noted that each model to be connected has a plurality of surfaces, each surface being characterized by corresponding model surface information. Alternatively, the model surface information may include, but is not limited to, size, location, thickness, normal, etc. of each surface of the solid model. The computer device may read model surface information of the target solid model stored in the memory.
S22, extending the surface of the target model according to the model surface information of the target entity model, and judging the intersection state between the extended surface of the target model and the model surfaces of other entity models.
Specifically, the computer device may extend the surface of the target model according to the model surface information of the target solid model, and determine the intersection state between the extended surface of the target model and each model surface of the other solid models one by one. The intersection status may include intersecting or non-intersecting. It should be noted that the other solid model is a solid model in the same model group as the target solid model, except for the target solid model. The target model surface is a surface which is selected on the target entity model and needs to judge the adjacent relation. If the adjacent relation of a plurality of surfaces on the target entity model needs to be judged, the method provided by the embodiment can be executed one by one.
S23, according to the intersecting state, determining the adjacent relation between the target model surface which is not extended and each model surface of other solid models.
Specifically, the computer device determines whether the original target model surface is adjacent to other model surfaces according to the intersection state of the extended target model surface and the other model surfaces. For example, if the extended object model surface intersects a surface, the computer device may determine that the two have an adjacent relationship; if the extended object model surface does not intersect with one surface, it can be determined that there is no adjacent relationship between the two. The adjacent relationship is used to define a relationship between different solid models. Alternatively, the adjacency relation may be a relation that characterizes whether two model surfaces are adjacent or not, or may be a relation that characterizes whether two entity models to which the two model surfaces belong are adjacent or not.
In this embodiment, the computer device obtains the model surface information of the target solid model, and extends the target model surface according to the model surface information of the target solid model, then determines an intersecting state between the extended target model surface and each model surface of the other solid models, and finally determines an adjacent relationship between the target model surface before extension and each model surface of the other solid models according to the intersecting state.
Alternatively, on the basis of the embodiment shown in fig. 4, one possible implementation manner of the step S22 may be as shown in fig. 5, including:
s221, generating corresponding virtual entities along the normal direction of the surface of each target model; the size of the virtual entity is the same as that of the surface of the target model, and the thickness of the virtual entity is used for representing a judging threshold value of the adjacent relation.
In particular, the computer device may generate the corresponding virtual entity normal to the target model surface. The size and shape of the virtual entity and the target model surface are the same. The virtual entity has a thickness, and the thickness may be set to be a value of a judgment threshold of the adjacent relationship. For example, if setting the distance between two objects to be less than or equal to 3 mm can be considered to be adjacent, the thickness of the virtual entity can be set to 3 mm; if the distance between two objects is greater than 3 mm, then it is considered that the two are not adjacent. Alternatively, the virtual entity may be transparent in the model set, and while possessing the attributes of the entity (such as intersection and collision, etc.), the presentation of other entity models is not affected.
S222, determining the adjacent relation between the target model surface and the model surface to be judged according to the intersecting state between each virtual entity and the model surface to be judged; the model surface to be judged is the model surface of the other entity models.
Specifically, the computer device may determine whether the virtual entity intersects with the model surface to be determined, thereby obtaining an intersection state between the virtual entity and the model surface to be determined. The intersection status may include intersecting or non-intersecting. It should be noted that, the model surface to be determined is a model surface of a physical model other than the target physical model, that is, the virtual physical surface does not need to determine an intersecting state with the model surface of the target physical model to which the virtual physical surface belongs. Specifically, the computer device determines whether the target model surface and the model surface to be judged have an adjacent relationship and whether the target entity model and other entity models have an adjacent relationship according to the intersecting state between the virtual entity and the model surface to be judged.
Alternatively, one possible implementation of this step may include: if the virtual entity intersects with the surface of the model to be judged, determining that the target model surface is adjacent to the surface of the model to be judged; and if the virtual entity is not intersected with the surface of the model to be judged, determining that the surface of the target model is not adjacent to the surface of the model to be judged. Specifically, if the virtual entity intersects with the surface of the model to be judged, determining that the target model surface corresponding to the virtual entity and the surface of the model to be judged have an adjacent relationship, are adjacent surfaces, and have an adjacent relationship between the target entity model and the entity model to which the surface of the model to be judged belongs; otherwise, if the virtual entity does not intersect with the surface of the model to be judged, it is determined that the model surface corresponding to the virtual entity does not have an adjacent relationship with the surface of the model to be judged, the model does not belong to an adjacent surface, and the target entity model and the entity model to which the surface of the model to be judged belongs do not have an adjacent relationship. In the implementation manner, the computer equipment determines that the target model surface and the model surface to be judged are adjacent surfaces and not adjacent surfaces respectively when the virtual entity and the model surface to be judged are intersected and not intersected respectively, so that the model surface and the entity model with adjacent relation can be accurately determined in a plurality of model surfaces.
In this embodiment, since the surface of the model to be determined is a model surface of another solid model other than the target solid model, and the size of the virtual entity is the same as that of the target model surface, and the thickness of the virtual entity can represent the determination threshold of the adjacent relationship, the computer device generates a corresponding virtual entity along the normal direction of each target model surface, and determines the adjacent relationship between the target model surface and the surface of the model to be determined according to the intersecting state between each virtual entity and the surface of the model to be determined.
