Description

Method and device for processing data of geometric modeling in computer aided design

Technical Field

The invention relates to the field of computers, in particular to a data processing method and device for geometric modeling in computer-aided design.

Background

At present, in geometric modeling of computer aided design, a process of combining a plurality of components together into a product is often included. For example, multiple parts and components are combined together to form a larger assembly. The components may be three-dimensional or two-dimensional geometric structures, which may be represented in various forms, such as a three-dimensional geometric structure represented by a solid object, a polyhedron, or a set of point clouds. These components may be simple components or may be more complex components that have a hierarchical structure. One part is a simple component and one assembly is a complex component, which itself is composed of parts and components having a hierarchical structure.

In CAD geometry, the rule used is to consider only one level of tie points when considering tie points that may form a pair. It is first determined which nodes are selected for use at a particular level, and then based on the relevant information stored at the nodes, relationships are automatically generated or follow-up actions are automatically performed. For example, a vehicle is a product assembly, which includes four wheel subassemblies in many subassemblies, each of which includes a tire, rim, bolt, nut, etc. any one or more of the wheel subassemblies or any one of the wheel subassemblies may have one or more associated attachment points, and when considering the attachment points that may form a pair, the rules used only consider that the attachment points at a particular level are insufficient to generate geometric relationships or perform subsequent actions on complex components, which limits the geometric modeling functionality of computer aided design.

In geometric modeling of computer-aided design, only geometric modeling operations between entities are limited, and geometric modeling operations of a component represented by a polyhedron or a group of point clouds cannot be realized, so that the geometric modeling function of computer-aided design is relatively limited.

In the geometric modeling of the computer aided design, rules used for determining the connecting points forming the pairing and control instructions influencing intelligent behaviors are only limited to be stored locally in a computer, so that the storage, updating and application efficiency of the rules and information required by the computer in the geometric modeling process is reduced, and the geometric modeling function of the computer aided design is influenced.

In the geometric modeling of computer aided design, the control rules and information related to the geometric modeling behavior of the component stored in the connecting point are only limited to the position, direction and size, or the information related to the purchase, the stock and the delivery time, so that the geometric modeling function of computer aided design is limited.

In the geometric modeling of the computer aided design, when a plurality of possible connecting points are matched, a designer is not allowed to change the selection of the matching through an interactive interface, so that the designer cannot artificially select a new method which is prior to the existing rules of a computer, the geometric modeling function of the computer aided design is limited, and the optimal effect of the geometric modeling of the computer aided design cannot be achieved.

In the geometric modeling of the computer aided design, certain intelligent behaviors can be triggered only when one component is dragged and moved to be combined with another component, and the pairing of connecting points cannot be triggered when the moving component is dragged and moved to a target component to be combined with each other through any interface, or when a geometric model of the moving component is modified through a pull rod or any other interface function and geometric data of the target component is referred to, and related geometric operations cannot be automatically executed according to rules and information on the paired connecting points, so that the geometric modeling function of the computer aided design is relatively limited.

Aiming at the problem that the geometric modeling function of computer aided design in the related art is relatively limited, no effective solution is provided at present.

The embodiment of the invention provides a data processing method of geometric modeling in computer aided design.

FIG. 1 is a flow chart of a method for processing data of geometric figure in computer aided design according to an embodiment of the invention. As shown in fig. 1, the flow chart of the data processing method for geometric modeling in computer aided design includes the following steps:

and step S101, determining a first component and a second component which have a matching relationship according to the matching model.

And determining a first component and a second component having a matching relationship according to the matching model, wherein the matching model is a model which is pre-established in computer aided design and is used for matching the first component and the second component, and the matching model is executable by the computing equipment, and the first component and the second component are components used for computer aided design. The component is a design member for designing a product by computer-aided design, and includes a process of combining a plurality of components together into a product. For example, multiple parts and components of a mechanical structure are combined to form a larger assembly. The components may be three-dimensional or two-dimensional geometric components, which may be represented in various forms, and optionally, a three-dimensional component may be represented by a solid, polyhedron, or a group of point clouds. The component may be a simple member or a more complex member having a hierarchical structure. One part is a simple component, while an assembly is a complex component, which itself is composed of parts and components having a hierarchical structure. A first component may be specified in a matching model executable on at least one computing device by specifying at least one second component in the matching model that is matchable to the first component.

When the first component and the second component have a matching relationship, such as when the first component and the second component are grouped, a geometric relationship, an engineering relationship, a manufacturing relationship, a material relationship, or other relationship may be automatically established between the two components. These relationships also need to be maintained in subsequent design changes.

For example, when a bolt and a nut are combined, the relative position, orientation and size of the bolt and the nut must satisfy the matching relationship when matching, so that the bolt and the nut can be reasonably combined together. The designer may choose to maintain these matching relationships for design purposes or as a design constraint between the two components. In addition, a cantilever beam welded to a post has not only a geometric relationship but also an engineering relationship representing the welding boundary conditions where the beam meets the post, which affects the physical behavior between the two components, especially when engineering simulations are performed, such as finite element analysis, are critical information.

When moving one member (moving member) to another member (target member) to be combined with each other using an interface instruction, or when referring to the geometric data of the other member (target member) when modifying the geometry of one member (moving member), a certain relationship between the two members may be automatically established or some subsequent action may be performed. The two components may be represented in various forms, such as three-dimensional components representing geometry using entities (typically generated by CAD software), polyhedrons (most 3D models that are downloadable over a network), point clouds (the result of laser scanning a 3D object), or other forms. The moving member and the target member may be represented in different forms, so that there may be intelligently designed behavior between either precise or approximate representations.

Step S102, determining the connection point of the first component according to the matching model and the component hierarchical structure.

The connection point of the first component is determined from the matching model and a component hierarchy, wherein the component hierarchy is established in the computer-aided design by at least a plurality of different levels of the first component and the second component. One or more connection points on the first component are determined in the matching model according to matching rules between the components.

The first and second assemblies may be a moving member and a target member, respectively. The first component and the second component may have a hierarchical structure, and the connection point may exist at any one of the hierarchies. One common hierarchy may be composed of product assemblies, sub-assemblies, and parts. The vehicle is a product assembly that includes a plurality of sub-assemblies including four wheel sub-assemblies, each of which includes a tire, rim, bolt, nut, and the like. A vehicle is formed by a hierarchy of vehicles, wheel subassemblies, or any component that may have one or more points of attachment associated therewith. When determining the connecting points which may form a pair, the rule used may be the relative priorities between the connecting points of different levels and the connecting points of different levels, so as to determine which pair of connecting points is selected, and then automatically generate a design relationship or execute a subsequent step of constructing a geometric model according to the information on the pair of connecting points, thereby avoiding automatically generating a design relationship or executing a subsequent step of constructing a geometric model through the connecting points on a specific level.

And step S103, determining the connection point of the second component matched with the connection point of the first component according to the matching model and the component hierarchical structure.

And determining the connection point of the second component matched with the connection point of the first component according to the matching model and the component hierarchy. A multivariate hierarchy of components having connection points can be determined from the hierarchy of the components by a hierarchical model in a CAD geometry model system executable on at least one computing device. And determining a second component matched with the first component through the hierarchical model according to the hierarchical rule and the diversified hierarchy of the components, and determining one or more connection points on the second component according to the matching model and the matching rule.

And step S104, matching the first component and the second component through the connection point of the first component and the connection point of the second component according to a preset matching rule to obtain matching data, and generating a matching component according to the matching data.

And matching the first assembly and the second assembly according to a preset matching rule through the connection point of the first assembly and the connection point of the second assembly to obtain matching data, and generating a matching assembly according to the matching data. According to a preset matching rule, matching the connection point of the first assembly with the connection point of the second assembly, so that the first assembly and the second assembly are matched to generate matching data, and then forming a matched assembly according to the matching data.

Step S105, a control instruction is received.

And matching the first assembly and the second assembly according to a preset matching rule through the connection point of the first assembly and the connection point of the second assembly to obtain matching data, and receiving a control instruction after generating a matching assembly according to the matching data. The control instruction is an intelligent rule for controlling the intelligent behavior of the paired components, and control information influencing the intelligent behavior of the components. The intelligent behaviors include engineering applications, manufacturing, materials, various general customized behaviors, and the like, and control instructions for achieving relevant design of position, direction, geometry, procurement, and the like of the entity by using the connection point. The intelligent rules for intelligent behavior of the paired components include geometric data rules, procurement data rules, engineering and processing rules, business rules, manufacturing and assembly rules, manufacturing process information, material rules, and any other customized rules and information.

And S106, executing operation on the pairing component according to the control instruction to obtain geometric data for constructing a geometric model.

And executing operation on the paired components according to the control instruction to obtain the geometric data for constructing the geometric model, wherein the control instruction is information for performing geometric modeling on the paired components, namely, applying intelligent behaviors on the paired components according to the intelligent rules to obtain the geometric data for constructing the geometric model.
