Description

Technical Field

[0001] The present invention mainly relates to the technical field of statistical engineering quantity of three-dimensional components, and in particular to a method for realizing rapid statistical engineering quantity of any three-dimensional component. Background Art

[0002] In traditional engineering design, the design of specialized components relies heavily on two-dimensional drawing techniques. This process not only requires manual component drawings, but also requires additional manual calculations of bills of quantities for various specialized components, such as process, civil engineering, and electrical engineering, during construction. However, manual calculations are particularly challenging when dealing with complex three-dimensional components (referred to as components).

[0003] In recent years, with the continuous development of Building Information Modeling (BIM) technology, its application in engineering design has become increasingly mature. Revit, a mainstream BIM 3D design software, has revolutionized engineering design and construction processes with its multiple advantages, including visualization, parameterization, digitization, collaboration, and simulation. Using Revit, designers from various disciplines can promptly identify and resolve overlaps between disciplines, more accurately calculate project quantities, and effectively achieve the goal of reducing costs and increasing efficiency.

[0004] Revit uses system components to draw major steel components such as stairs and railings, and system-loaded components to draw concrete components such as walls, floor slabs, and structural foundations. Externally loaded components are used to draw other steel and concrete components, complex-shaped components, and other specialized components. Nested components inevitably occur within system-loaded and externally loaded components. Because nested components within components may differ from the component type of the component itself, all Revit components (except system components) include a shared attribute. For loaded components with shared attributes, Revit's bill of materials function can independently calculate their project quantities, regardless of whether they are nested components within other components.

[0005] However, at different stages of construction, it's often necessary to count quantities for specific floor components or selected areas. Furthermore, Revit's schedule functionality is insufficient for counting quantities for any selected area, limiting its flexibility. Furthermore, because Revit doesn't recognize shared components nested within components within a selected area by default, without special processing, the quantity counts for some shared, nested components will be missing.

[0006] Therefore, in response to the above problems, it is necessary to improve and optimize the existing component engineering quantity statistics method. Summary of the Invention

[0007] Traditional engineering design has long suffered from the problem of relying on manual calculations for the quantities of various specialized components, resulting in a lack of guaranteed design efficiency and accuracy. In the practice of Building Information Modeling (BIM) design, the Revit bill of materials function can only count quantities by component category or specific attributes, and is unable to count the quantities of components in any selected area. Revit is unable to recognize shared components nested within components in a specific selected area by default, resulting in missing quantity statistics for some components. In view of this, and to address the problems of the prior art, the present invention provides a method for rapidly counting the quantities of any three-dimensional component, which can improve statistical efficiency, accuracy, and flexibility, while reducing operational complexity and improving ease of use.

[0008] To achieve the above object, the present invention provides a method for quickly calculating the engineering quantity of any three-dimensional component, comprising the following steps: Step 1: Create various models of the workshop in Revit, including system components, system loaded components, external loaded components, model groups, and parts, to form a 3D workshop model diagram. The model groups are composed of the same system components, the same system loaded components, or the same external loaded components, and the parts include one or more system components, system loaded components, and external loaded components. Step 2: In the 3D model diagram, select one or more models in any area; Step 3: Execute the program, which directly obtains the ID set of the selected system components, system loaded components, and externally loaded components; Step 4: The program obtains the component ID set contained in the selected model group and parts through processing; Step 5: Merge the component ID sets obtained in steps 1-4 to obtain any deeply shared nested component IDs contained in the components of the merged set; Step 6: Merge all acquired component ID sets, obtain component information through the IDs in the merged set, including component type, material, and volume information, and export it as a component bill of quantities.

[0009] Furthermore, the procedure of step 4 processes the method of obtaining the component ID set, including step 7: in Revit, obtaining the component IDs contained in the model group and the component by calling the getMemberID method.

[0010] Furthermore, in step 5, any shared nested components of any depth contained in any component in the merged set are obtained through a while loop method, which includes the following steps: S1: declare that the while loop method will collect all shared nested component sets contained in any component in the merged set and use them as the return value of the while loop method; S2: define any component in the merged set of step S1 as the first level, the next level of shared nested components as the second level, and traverse to define the next level of shared nested components as the Nth level; S3: Call GetSubComponentIds of the first level to obtain the shared nested component collection of the second level; S4: Using the while loop method, the first determination condition is whether the shared nested component set at the second level is empty. If it is empty, the loop terminates. If it is not empty, the shared nested components of the second level are collected into the shared nested component set of step S1; S5: Call GetSubComponentIds of the second level to obtain the shared nested component set of the third level; S6: Continue executing the while loop to determine whether the shared nested component set at the third level is empty. If it is empty, the loop stops. If it is not empty, the shared nested components of the third level are collected into the shared nested component set of step S1; S7: If the nesting level of the shared nested component is greater than or equal to 3, the while loop is traversed and executed until the judgment condition is empty.

[0011] Furthermore, in step 6, the volume of each component is calculated by first obtaining the material volume through the GetMaterialIds method. If the component is not assigned a material, the volume of its geometric shape is obtained using the GetInstanceGeometry method.

[0012] Beneficial effects: The present invention provides a method for realizing rapid quantity statistics of arbitrary three-dimensional components. Through the secondary development technology of Revit, rapid quantity statistics of three-dimensional components in a specific selected area or an arbitrary selected area are realized, thereby avoiding the low efficiency and error problems of traditional manual calculations and improving design efficiency and accuracy. The present invention can quickly identify and obtain quantity information of shared nested components nested at any depth inside other components in the selected area without creating a Revit bill of materials, thereby simplifying the process of quantity statistics, reducing operation complexity and improving usability, and ensuring the integrity and flexibility of quantity statistics. The present invention uses a loop method to obtain shared nested components of any depth, making the quantity statistics of complex components simpler and more efficient. The present invention innovatively uses the method of obtaining geometric shapes to obtain the volume of components, thereby realizing quantity statistics of components without material assignment, solving the problem that the existing method cannot count the quantity of components without material assignment, and ensuring the accuracy and comprehensiveness of quantity calculation.

DETAILED DESCRIPTION

[0014] like Figures 1 to 5 As shown, the present invention provides a method for quickly calculating the engineering quantity of any three-dimensional component. Example 1

[0015] A method for quickly calculating the engineering quantity of any three-dimensional component comprises the following steps: Step 1: Create various models of the workshop in Revit, including system components, system loaded components, external loaded components, model groups, and parts, to form a 3D workshop model diagram. The model groups are composed of the same system components, the same system loaded components, or the same external loaded components, and the parts include one or more system components, system loaded components, and external loaded components. Step 2: In the 3D model diagram, select one or more models in any area; Step 3: Execute the program, which directly obtains the ID set of the selected system components, system loaded components, and externally loaded components; Step 4: The program obtains the component ID set contained in the selected model group and parts through processing; In Revit, get the member ID contained in the model group and component by calling the getMemberID method; Step 5: Merge the component ID sets obtained in steps 1-4 to obtain any deeply shared nested component IDs contained in the components of the merged set; In step 5, the shared nested components of any depth contained in any component in the merged set are obtained through a while loop method, which includes the following steps: S1: declare that the while loop method will collect all shared nested component sets contained in any component in the merged set and use them as the return value of the while loop method; S2: define any component in the merged set of step S1 as the first level, the next level of shared nested components as the second level, and traverse to define the next level of shared nested components as the Nth level; S3: Call GetSubComponentIds of the first level to obtain the shared nested component collection of the second level; S4: Using the while loop method, the first determination condition is whether the shared nested component set at the second level is empty. If it is empty, the loop terminates. If it is not empty, the shared nested components of the second level are collected into the shared nested component set of step S1; S5: Call GetSubComponentIds of the second level to obtain the shared nested component set of the third level; S6: Continue executing the while loop to determine whether the shared nested component set at the third level is empty. If it is empty, the loop stops. If it is not empty, the shared nested components of the third level are collected into the shared nested component set of step S1; S7: If the nesting level of the shared nested component is greater than or equal to 3, then the while loop is executed until the judgment condition is empty; Step 6: Merge all acquired component ID sets, obtain component information through the IDs in the merged set, including component type, material, and volume information, and export it as a component bill of quantities; The calculation of the volume of various components first obtains the material volume through the GetMaterialIds method. If the component is not assigned a material, the GetInstanceGeometry method is used to obtain the volume of its geometric shape. Example 2

[0016] like Figure 1 As shown, a method for quickly calculating the engineering quantity of any three-dimensional component includes the following steps: Create various components of the cement factory kiln workshop in Revit to form a three-dimensional model of the workshop, such as Figure 1 As shown; In the 3D model, select all components of the foundation and ground floor, such as Figure 2 As shown; Execute the program, and the program directly obtains the ID sets of the selected structural column components, structural foundation components, chimney components, etc. The pile foundation components are in the model group, such as Figure 3 As shown, the material is "concrete, cast in place - C30". The program obtains the component ID and related information of the pile foundation in the selected model group by calling the getMemberID method, such as Figure 5 As shown in row 2; Merge the component ID sets obtained in the above steps, where the spiral ladder of the chimney component shares the nested component, such as Figure 4 As shown in the figure, the program obtains the spiral ladder shared nested component ID and related information by calling the GetSubComponentIds method of the chimney component. Since the spiral ladder component 3D model has no material assigned, the GetInstanceGeometry method is used to obtain the volume of its geometric shape, and the material information is replaced with its component name information, as shown in the figure. Figure 5 As shown in line 25; Merge all acquired component ID sets, obtain component type, material, volume and other information through the ID in the set, and export it as a component bill of quantities, such as Figure 5 shown.
