Problems solved by technology

[0002] In the current engineering design project, the process design has the characteristics of huge drawings and a large amount of data, but the engineering project has requirements for design time, and additional entry of attribute tables will cause problems such as tight time, heavy tasks, low efficiency, and error-prone
[0003] Existing AutoCAD does not have the function of directly exporting block attributes, and the export performance of conventional plug-ins is poor, and this part of the function is weak or missing, such as only outputting txt without preview function, unable to verify, check code, and unable to export required columns etc.

Embodiment 1

[0037] In a design project, there are 27 process flow charts in total, and there are 7108 drawing block objects in total. Using the identification and export method of the present invention, the following data are obtained:

[0038] Designer: 1 person.

[0039] Open the AutoCAD program, load the DLL program, read in and open the project drawing, use the DLL package command to complete the frame selection of the drawing block, the computer will automatically complete the block data generation form of all drawings within 5 seconds, select the template and output it to the Excel file , the whole process takes about 1 minute in total, and there is no manual error or omission, which improves the work efficiency and accuracy of designers.

Embodiment 2

[0041] In a certain design project, there are 2 process flow charts in total, and there are 2,376 drawing block objects in total. Using the identification and export method of the present invention, the following data are obtained:

[0042] Designer: 1 person.

[0043] Open the AutoCAD program, load the DLL program, read in and open the project drawing, use the DLL package command to complete the frame selection of the drawing block, the computer will automatically complete the block data generation form of all drawings within 2 seconds, select the template and output it to the Excel file , the whole process takes about 1 minute in total, and there is no manual error or omission, which improves the work efficiency and accuracy of designers.

Embodiment 3

[0045] In a certain design project, there is a total of 1 process flow chart, and there are 439 drawing block objects in total. Using the identification and export method of the present invention, the following data are obtained:

[0046] Designer: 1 person.

[0047]Open the AutoCAD program, load the DLL program, read in and open the project drawing, use the DLL package command to complete the frame selection of the drawing block, the computer will automatically complete the block data generation form of all drawings within 1 second, click Edit Template, and only select "Inventory" Name" and "Specification Model" columns, and define a new template named "Equipment and Specification". After confirmation, it will automatically switch to the export column template, which can be previewed in the table of the export panel and output to an Excel file. The whole process is total It takes about 2 minutes and there is no human error or omission, which optimizes and simplifies the pract...

Abstract

The invention discloses a block attribute identification and export method based on AutoCAD. The method is characterized by specifically comprising the following steps: opening a drawing and selecting a preset area or totally selecting the preset area; judging whether a filtering block is needed and executing corresponding operation; traversing and acquiring attribute values of the blocks, judging whether rows with the same attributes exist or not, and executing corresponding operation; generating a specific attribute value table according to a template defined by a user or a default template, and placing the specific attribute value table into a table control; comparing the block name and the code with the standard code of the corresponding block and marking; and displaying an export panel with a preview table, and selecting, exporting and storing the export panel as an Excel file. According to the method, the block attributes in the process flow diagram are directly output to Excel, so that the workload of process designers is reduced, and the overall speed of design work related to flow diagram drawing is increased. Manual errors are reduced, and the problems caused by the manual errors can be avoided by means of the accuracy and the fatigue-free property of the working of the computer. According to the method, the process design accuracy is greatly improved.

Description

technical field [0001] The invention is applied to the secondary development field of Excel and AutoCAD, and is specifically an AutoCAD-based block attribute identification and export method. Background technique [0002] In the current engineering design project, the process design has the characteristics of huge drawings and a large amount of data, but the engineering project has requirements for design time, and additional entry of attribute tables will cause problems such as tight time, heavy tasks, low efficiency, and error-prone . [0003] Existing AutoCAD does not have the function of directly exporting block attributes, and the export performance of conventional plug-ins is poor, and this part of the function is weak or missing, such as only outputting txt without preview function, unable to verify, check code, and unable to export required columns etc. Therefore, it is necessary to adopt the block attribute identification and export method based on the secondary d...
