Abstract
Description
Technical Field
[0001] This invention belongs to the field of computer-aided design software information processing, and specifically relates to a method for batch modification of process equipment product drawing numbers in Catia software. Background Technology
[0002] Process equipment typically refers to equipment used in the production process for processing, inspecting, and transporting prepregs, parts, or components. It is widely used in aerospace, machinery, and automotive industries, and its types and quantities are rapidly increasing with product complexity. During the conceptual and preliminary design stages, because design requirements are not yet fully finalized, frequent changes to product information are often necessary. Drawing numbers, as one of the explicit characteristics of process equipment, are often used as unique identifiers and frequently need to be changed at this stage. Currently, due to the lack of effective methods for batch changing drawing numbers, process equipment designers often need to manually change the numbers and reference links of various sub-modules in the modeling tree, resulting in low efficiency and a high risk of errors. Summary of the Invention
[0003] The purpose of this invention is to address the problems of low efficiency and error-proneness in the process of changing process equipment drawing numbers using existing technologies. It proposes a method for batch changing process equipment product drawing numbers based on Catia secondary development, which can batch change the instance name, part number, and reference links of process equipment drawing numbers, thereby improving the efficiency of drawing number changes and further shortening the development cycle of the process equipment conceptual design stage.
[0004] To achieve the above objectives, the technical solution of the present invention includes the following steps: A method for batch changing the drawing numbers of process equipment products based on Catia secondary development includes the following: Step S1: Organize all process equipment products with drawing numbers to be changed, and open one of the process equipment products with drawing numbers to be changed in Catia. Step S2: Obtain the current active window document object of Catia. The current active window document object of Catia is the process equipment product document object with the drawing number to be changed that is currently open. Step S3: Determine whether the document object obtained in step S2 is empty. If it is empty, exit the implementation process to end. If it is not empty, proceed to step S4. Step S4: Obtain the root product object rootProduct from the process equipment product assembly tree; Step S5: Using the root product object rootProduct as the reference, recursively traverse the assembly tree, collect each product encountered, and obtain the collection container collectedProductItems containing all product objects. Step S6: Enter the name of the original drawing number and the name of the changed drawing number for the process equipment product whose drawing number is to be changed; Step S7: Determine whether the input content in step S6 is empty. If it is empty, exit the implementation process to end. If it is not empty, proceed to step S8. Step S8: Iterate through the product collection container collectedProductItems obtained in step S5. Based on the original drawing number name and the changed drawing number name mentioned in step S6, construct the product file after the change of each product through the file system object API. At the same time, collect the original product document object of each product to obtain the collection container deletedFileItems containing all product document objects to be deleted. Step S9: Traverse the collection container collectedProductItems described in step S5, and determine whether it is the root product node object. If it is the root product node object, skip the processing of the current product object. If it is not the root product node object, replace the reference links of the other product node objects in the assembly tree through the Catia secondary development interface. Step S10: Traverse the collection container collectedProductItems described in step S5, and determine whether it is a root product node object. If it is a root product node object, skip the processing of the current product object. If it is not a root product node object, obtain the instance name before the change through the Name property of the product node object, replace the instance name before the change with the original drawing number name and the changed drawing number name described in step S6, and bind the changed instance name to the product node object. Step S11: Traverse the collection container collectedProductItems described in step S5, obtain the part number before the change through the PartNumber property of the product node object, replace the part number before the change with the original drawing number name and the changed drawing number name described in step S6 as the basis, and bind the changed part number to the product node object. Determine if it is a root product node object. If it is, save the current product node. If it is not a root product node object, save the document objects of the current product node and its parent node, and complete the change of part number for each product node in the assembly tree. Step S12: Save and close the active window document object obtained in step S2; Step S13: For the collection container deletedFileItems containing the path information of the product documents to be deleted mentioned in step S8, delete each product document through the file system object API to complete the batch change of the process equipment product drawing number. Step S14: Open the next process equipment product with the drawing number to be changed in Catia; repeat S2-S13 to complete the drawing number change for all process equipment products with the drawing number to be changed.
[0005] Furthermore, in step S2, the document object of the currently active window is obtained, and the steps include the following: S2a, obtains the object instance catiaAppInstance of the Catia application's running process through the GetObject interface; S2b: Obtain the currently active window document object through the activeDocument property of the object instance catiaAppInstance described in step S2a; the root product object rootProduct mentioned in step S4 is obtained through the Product property of the currently active window document object described in step S2b.
[0006] Furthermore, in step S5, the collection container `collectedProductItems` containing all product objects is obtained. The implementation steps include the following: S5a, add the root product object rootProduct from step S4 to the collection container collectedProductItems; S5b: Obtain all child product object containers of the current product node through the Products property of the root product object rootProduct; traverse the child product object containers and add each item to the collection container collectedProductItems. S5c, taking each item of the sub-product object container described in step S5b as the current root node object, repeat steps S5a and S5b to collect all product node objects on the process equipment assembly tree, and obtain a collection container collectedProductItems containing all product objects.
[0007] Furthermore, in step S8, the modified product document is constructed through the file system object API, and the collection container `deletedFileItems` containing the path information of all product documents to be deleted is obtained. The implementation steps include the following: S8a, obtain the absolute position of the root product object in the resource manager, rootProductPath, through the ReferenceProduct.Parent.FullName property of the root product object rootProduct described in step S4; S8b, based on the absolute location rootProductPath described in step S8a, obtain the file directory where the process equipment product is located through the GetDirectoryName interface; S8c: Iterate through the collection container collectedProductItems described in step S5c. For each product item, obtain the document name before the change through the ReferenceProduct.Parent.Name property. Based on the original drawing number name and the changed drawing number name described in step S6, replace the document name before the change with the Replace interface. Concatenate the file directory and the changed document name described in step S8b through the Combine interface to obtain the absolute position of the changed product in the resource manager. Iterate through all file items in the file directory described in step S8b, find the file item object with the same document name as described in S8c, and obtain the document object of the product before the change. With the absolute position of the changed product as input, construct the document of the changed product through the Copy method of the file item object. S8d, add the document object of each product before the change as described in step S8c to the deletedFileItems container described in step S8, thereby collecting all document objects of products to be deleted.
[0008] Furthermore, the determination of whether the current product is the root product object mentioned in steps S9-S11 is obtained by obtaining the corresponding instance name and part number through the Name and PartNumber properties of the current product object. When the two values are the same, the current product node is regarded as the root product object.
[0009] Furthermore, step S9 involves modifying the reference links of the product node objects. The steps include the following: S9a, the document name of the parent node of the current product item can be obtained through the Parent.Parent.ReferenceProduct.Parent.Name property; S9b, obtain the Catia document set object through the Documents property of the object instance catiaAppInstance described in step S2a; S9c, taking the document name of the parent node product of the current product item as described in step S9a as input, obtain the document object of the parent node product of the current product item through the Item method of the Catia document set object described in step S9b, and obtain all the product sets of the parent node product document object of the current product item through the Product.Products property; S9d, taking the absolute positions of the current product and the modified product in the resource manager as input, uses the ReplaceComponent method of all product sets of the parent node product document object of the current product item as described in step S9c to change the reference link of the product node object.
[0010] Furthermore, in step S10, the product object instance name is changed and the changed instance name is rebound to the product node object. The implementation steps include the following: S10a, obtain the instance name of the product object before the change through the Name property of the current product object; S10b: Using the original drawing number name and the changed drawing number name described in step S6 as input, the instance name of the changed product is obtained through the Replace method of the product instance name before the change described in step S10a; S10c, rebind the changed product instance name described in step S10b to the Name property of the current product object to realize the change of the product instance name.
[0011] Furthermore, in step S11, the part number of the product object is changed and the changed part number is rebound to the product node object. The steps to achieve this include the following: S11a, obtain the part number of the product object before the change through the PartNumber property of the current product object; S11b, using the original drawing number name and the changed drawing number name as described in step S6 as input, the part number of the changed product is obtained through the Replace method of the part number before the change described in step S11a; S11c, Rebind the part number of the changed product described in step S11b to the PartNumber property of the current product object to realize the change of the product part number; The saving of the current product node mentioned in step S11 is achieved through the Save method of the current product node object. The saving of the document object of its parent node mentioned in step S11 is achieved through the Save method of the product document object of the parent node of the current product item as described in step S9c.
[0012] Furthermore, the saving and closing of the active window document object mentioned in step S12 is achieved through the Save and Close methods of the active window document object described in step S2b.
[0013] Furthermore, in step S13, each item in the collection container deletedFileItems, which contains all product document objects to be deleted, is deleted using the file system object API. The steps include the following: S13a, Traverse the collection container deletedFileItems described in step S8d to obtain each document object to be deleted; S13b: By using the Delete method of each document object to be deleted as described in step S13a, the deletion operation of all product document objects to be deleted is realized.
[0014] Compared with existing technologies, the present invention has the following advantages: First, the efficiency and accuracy of changing process equipment drawing numbers are high.
[0015] The method of this invention uses the instance names of each product node in the process equipment modeling tree as a reference benchmark. Based on the Catia secondary development interface, it modifies the drawing number and reference link of each product node, ensuring that all nodes in the modeling tree are processed accurately and efficiently, and improving the efficiency and accuracy of process equipment drawing number changes.
[0016] Second, the reference links for changes to process equipment drawing numbers are stable.
[0017] The method of this invention, in the process of processing the reference links of each product node on the process equipment modeling tree, first constructs and replaces the modified product documents to ensure that the reference links of each product node are rebound, and then deletes the product documents before the change. This ensures that the modified reference links are correctly mounted on the corresponding product nodes, and improves the stability of reference links when the process equipment drawing number is changed.
