Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of engineering digitization, and in particular, to a parametric component modeling method and system across engineering stages. BACKGROUND

[0002] Parametric components are widely used in BIM software, and mainstream BIM platforms (such as BIMBase, Revit, and Microstation) have their own parametric component modeling tools. These tools usually calculate a geometric model based on a series of parameters and can well establish a model in a single scenario.

[0003] However, for buildings, there are multiple stages of surveying, design, construction, and operation and maintenance in the civil engineering industry. The same component object may have different geometric expressions and expression accuracies in different stages. The current parametric components do not consider the stage element, and when crossing stages, they often cannot efficiently utilize the design achievements of the previous stage. For example, in the construction stage, the component model in the design stage often needs to be divided into segments for construction. At present, the most common solution is to reestablish the construction model or use a segmentation tool to segment the geometric model, which results in inefficient data and model transmission across different stages and increases the labor cost and time cost. Therefore, there is an urgent need for a new method of managing and using parametric components across stages. SUMMARY

These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure by any means, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0034] The present disclosure will be further described below in conjunction with the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present disclosure, and cannot limit the protection scope of the present disclosure.

[0035] Term explanation:

[0036] CSG (Constructive Solid Geometry, geometric construction entity method): a modeling technology for building a three-dimensional entity model. Its core idea is: a complex three-dimensional shape can be obtained by combining a series of simple three-dimensional geometric primitives (called "voxels" or "primitives") through stretching, sweeping, rotating, Boolean operation (union, difference, intersection) and other ways. It converts the complex geometric creation process into a geometric logical expression that can be explicitly described, stored and reused.

[0037] As shown in Figure 1 The first embodiment of the present disclosure provides a cross-engineering stage parameterized component modeling method, which includes the following steps:

[0038] S1, defining attribute data of the component in multiple engineering stages, the attribute data including common attributes shared by all engineering stages and private attributes of each engineering stage; the specific steps are as follows:

[0039] S11, defining multiple engineering stages of the component, the engineering stages including at least a design stage, a construction stage and a maintenance stage;

[0040] The different stages (such as the design stage, the construction stage, the maintenance stage, etc.) that the component may exist in the future are defined, and each stage has different modeling requirements.

[0041] S12, defining common attributes shared by all engineering stages;

[0042] As Figure 2 shown, common attributes are defined for components of each stage, such as component type, name, number, etc., which can be kept consistent in all stages to ensure data consistency between different stages.

[0043] S13, define private attributes of each engineering stage;

[0044] According to the special needs of each stage, define stage private attributes for each stage.

[0045] For example, the design stage considers geometric properties, material properties, functional properties, structural properties, environmental impact properties, etc. For example, geometric properties include size, layout, structural form, material properties include material specification, material type, functional properties include use function, spatial distribution, service facilities, structural properties include load, seismic performance, compressive strength, corrosion resistance, environmental impact properties include energy consumption, carbon emissions, wind resistance, water level, etc.

[0046] The construction stage considers construction technology, material management, etc. For example, construction technology includes cutting distance, construction steps, construction progress, etc., and material management includes material quality, material testing, etc.

[0047] The operation and maintenance stage considers vendor information, safety monitoring, energy efficiency management, environmental impact, etc. Vendors include suppliers, production date, expiration date, appearance size, etc., safety monitoring includes cracks and settlement, electrical inspection, etc., energy efficiency management includes electricity, gas, water, etc., and environmental impact includes noise monitoring, water quality monitoring, etc.

[0048] Referring to Figure 2 shown, the private attributes of different stages can also be set to have inheritance relationships, such as different stages paying attention to size information, and subsequent stages inheriting size-related attributes of previous stages to ensure the uniqueness of information.

[0049] S2, create corresponding parametric component templates for each engineering stage, wherein the parametric component templates of subsequent stages are formed by inheriting the common attributes, private attributes and geometric logical expressions of the parametric component templates of previous stages, and making modifications to adapt to the needs of the current stage; the specific steps are as follows:

[0050] S21, call modeling tools of different stages to create corresponding parametric component templates for each engineering stage; when creating a template for a subsequent stage and selecting an existing previous stage component as a basis, the system will automatically load the common attributes, private attributes and geometric logical expressions of the previous stage template based on the inheritance relationship, and then the system will automatically extend the geometric logical expressions and add attributes specific to the subsequent stage, thereby forming a parametric component template that adapts to the needs of the subsequent stage.

[0051] It can be understood that the geometric modeling model of each stage is different. For example, the component in the design stage needs overall high-precision and detailed geometric expression, and the construction stage is concerned about how to build the building, and there is a segmentation and segmentation construction segmentation requirement. Therefore, when building the model, different geometric logic is defined according to the stage, and different modeling tools are provided.

[0052] The modeling tool is a command directly operated by the user on the software interface. The software provides different mode buttons or toolbars such as "design stage modeling", "construction stage modeling", "operation and maintenance stage modeling", etc. Each tool is encapsulated with a set of predefined geometric logic bound to the stage.

[0053] Taking a bridge pier component as an example, when the user selects an existing design stage bridge pier component, the system will automatically load the properties and geometric logic of the design stage bridge pier template based on the inheritance relationship. Then, the user selects the segmentation tool of "construction stage modeling", and extends the parameters specific to this stage, that is, defines new parameters of the construction stage, such as segmentation distance d1 and segmentation distance d2.

[0054] At the same time, on the basis of the inherited geometric logic expression, "processing" logic is added, such as Boolean operation (especially difference set for cutting), array operation, etc. to meet the segmentation and block requirements. For example:

[0055] Complete pier = Inherited design stage pier / / Get the inherited complete component;

[0056] Cutting plane 1 = CreatePlane (Height = d1) / / Create a virtual cutting plane at height d1;

[0057] Cutting plane 2 = CreatePlane (Height = d2) / / Create another virtual cutting plane at height d2;

[0058] [Section 1, Section 2, Section 3] = SplitByPlanes (complete pier, [cutting plane 1, cutting plane 2]) / / Cut the complete pier into three sections.

[0059] S22, store the parametric component template of each stage to form a parametric component template library.

[0060] According to the concept of CSG geometric construction, the geometric logic expression is extracted, which is stored in a custom file after being binary, such as "design-pier.comp", "construction-pier.comp", "operation and maintenance-pier.comp", etc. Form a parametric component template, and gradually form a parametric component template library.

[0061] S3, according to the current stage of the engineering project, calling the corresponding parameterized component template and inputting instance parameters to generate a staged instance component model; when the engineering stage is switched, automatically triggering a component model updating event and updating the instance component model based on the parameterized component template corresponding to the current stage.

[0062] Specifically, the current stage is set in the engineering environment, and according to the current engineering stage, it is determined which component to use, the parameterized component model is established using the parameterized component template stored in step S2, and the actual value input by the user is used.

[0063] When the engineering project enters a new stage, the system automatically identifies the current stage, triggers a model updating event, automatically switches the geometric form of the component model, and can be parameterized and edited again to update the instance model.

[0064] As shown in Figure 3 The second embodiment of the present disclosure provides a parameterized component modeling system 100 across engineering stages for running each step of the above-mentioned parameterized component modeling method across engineering stages, and the system comprises:
