Description

A CAD drawing file batch processing system and method

Technical Field

The present invention relates to the technical field of CAD drawing file processing, and in particular to a CAD drawing file batch processing system and method thereof.

Background technique

Computer-aided design (CAD) technology is an indispensable tool in the modern design industry, which can significantly improve design efficiency and quality. CAD software is usually used to create and modify design data such as engineering drawings and 3D models. In the construction engineering industry, CAD files usually contain detailed design information and graphic representations. With the development of technology, the functions of CAD software are also constantly expanding to support more complex design and analysis tasks.

In practical applications, designers often need to process CAD files for printing. The need for batch processing of CAD file printing also arises, which can be achieved by using specialized CAD editor software. For example, Xunjie CAD Editor is a software that can realize batch printing of CAD drawings. Using this type of software, users can add multiple CAD files at one time, make print settings, and then print them out in batches, greatly improving work efficiency.

In addition, CAD files often need to be shared with others or archived, so converting CAD files to PDF format is also a common batch processing requirement. PDF format is favored because of its cross-platform, easy to view and share features.

For batch printing of engineering CAD files, factors such as printer settings, paper size, and print layout also need to be considered.

Currently, some batch processing programs on the market, such as "BatchPlot.VLX", "Easy to Draw" and other professional CAD software, provide the function of automatically searching and printing multiple drawings, which simplifies the operation process of batch printing to a certain extent, but there are more or less problems such as complicated and cumbersome operation, repetitive settings, complex settings, and poor versatility.

Therefore, it is necessary to provide a batch processing system and method for CAD files to make the design work more efficient and convenient.

Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a CAD drawing file batch processing system and method. The present invention can effectively simplify the printing operation process. It only needs to set the configuration parameters of the device according to the current environment in advance. Batch printing can be achieved with simple operations for different CAD drawings, which greatly simplifies the operation process and avoids repeated settings. At the same time, it does not rely on the local CAD software version and has good versatility.

To achieve the above object, a method for batch processing of CAD drawing files designed by the present invention comprises the following steps:

S1: Link the CAD drawing file through COM technology, match it with the preset print frame block of the program, and filter to obtain the print frame block actually used in this CAD drawing file;

S2: pre-processing the frame block to be printed, obtaining the position coordinates of the object to be identified in the frame block to be printed, and saving them through the data saving module as a proprietary database of this drawing;

S3: The user selects the frame of the drawing to be printed in the current CAD drawing through the user interface module, and obtains a list of the frames to be printed in the entire drawing file;

S4: Read the proprietary database, apply it to each frame block in the list of frames to be printed, find the object whose information needs to be identified in the drawing by identifying the position of the object, and obtain the relevant information corresponding to each drawing;

S5: After the user confirms that the information is correct, the printer in the CAD software program is called to output the PDF format files of the printed drawings one by one to the file path where the drawings are located.

As a preferred implementation method, in step S1, the CAD drawing file is linked through COM technology to form an effective data transmission channel, and the transmitted data is converted through a data conversion module. After the channel is established, all blocks in the block manager of this CAD drawing file are obtained, matched with the program preset frame blocks to be printed, and filtered to obtain the printing frame blocks actually used in this CAD drawing file.

As a preferred implementation, in step S2, the frame block to be printed is a pre-set block with the drawing printing range as the boundary, and is defined as different frame blocks according to the size of the printing range. Each frame block contains a range box of the object to be identified.

As a preferred implementation, in step S2, the position coordinates of the object to be identified in the frame block to be printed are obtained, including the drawing name, drawing number, and the position coordinates of the drawing sheet.

As a preferred implementation, in step S3, the preset name of the frame block to be printed is used as the frame block selection filter, and the selection method can be a method of scanning the entire image objects one by one or allowing the user to select the object.

As a preferred implementation, in step S4, the CAD operation identification module reads the generated drawing-specific database from the data storage module, applies it to each frame block in the list of frames to be printed, finds the object whose information needs to be identified in the drawing by identifying the position of the object, and obtains the relevant information corresponding to each drawing.

As a preferred implementation, in step S4, relevant information corresponding to each drawing including drawing name, drawing number, and specific content of the drawing is obtained, and this information is then transmitted back to the CAD operation identification module through the data transmission conversion module for processing and displayed on the user interface.

As a preferred implementation, in step S5, the user can customize the naming method of the file name by setting keywords to specify the drawing name, drawing number, and drawing size, and use the combination of drawing information that can be identified by the proprietary database as the output print file name.

As a preferred implementation, in step S5, the drawing information identified by the proprietary database is sorted in the natural order of the drawing numbers, and the printed drawing information is output in an Excel file format as a drawing catalog.

The present invention also provides a system for implementing the above-mentioned CAD drawing file batch processing method, comprising: a data transmission conversion module, used for performing data transmission between an operating system and a CAD software program, and the transmitted data is converted into a data form recognizable by the operating system through the module, so that the operating system and the CAD software program can recognize each other;

There is no need to repeatedly set the relevant parameters of the system, which simplifies the printing workflow.

Secondly, the CAD drawing file batch processing method of the present invention pre-processes the linked CAD current file and saves the relevant coordinate information as a proprietary database of the drawing. There is no need to set the drawing configuration each time, which further simplifies the user operation process.

Thirdly, the CAD drawing file batch processing method of the present invention saves the specific coordinate position of the drawing frame to be printed in the space system, the drawing name, drawing number and other information, and generates a print file name corresponding to the drawing name. The user does not need to modify the file name after printing, which further simplifies the printing workflow, standardizes the file naming method, and facilitates file archiving.

Fourthly, the CAD drawing file batch processing method of the present invention can output the printed drawing information in Excel format, which simplifies the manual writing of the drawing catalog and improves the writing efficiency.

Fifth, the CAD drawing file batch processing method of the present invention simplifies the user's tedious drawing printing and directory writing operations, greatly improving work efficiency.

Detailed ways

The following is a detailed description of the implementation of the present invention in conjunction with the implementation cases, but they do not constitute a limitation of the present invention and are only given as examples. At the same time, the advantages of the present invention will become clearer and easier to understand through the description.

A CAD drawing file batch processing system as shown in Figure 1 includes: a data transmission conversion module, which is used to transmit data between the operating system and the CAD software program, and the transmitted data is converted into a data form recognizable by the operating system through the module, so that the operating system and the CAD software program can recognize each other; a CAD operation recognition module, which is used to process the CAD operation instructions in the program, including object recognition and related attribute acquisition, printing operation, and logical operation; a data storage module, which is used to save the internal operating parameters and related setting parameters of the device, and record predefined frame block information; a user interface module, which is used for the user and program interface interaction platform.

A method for batch processing of CAD drawing files as shown in FIG2 includes the following steps:

S1: In the data transmission conversion module, the CAD drawing file is linked through COM technology to form an effective data transmission channel. After the channel is established, all blocks in the block manager of this CAD file are obtained, matched with the program preset frame blocks to be printed (through the block name attribute), and the printing frame blocks actually used in this CAD drawing file are filtered. It should be pointed out that the data transmitted between these programs and CAD files must be converted through the data transmission conversion module. Data conversion is because the operating system cannot recognize the internal data structure of the program when applying COM technology, and the data needs to be converted into a data form that the system can recognize.

In the CAD operation identification module, the program operation may be too fast, and the data transmission conversion module and the CAD drawing file may not have enough time to form an effective transmission. Therefore, the data transmission conversion module is needed to identify whether the data is legal. If the data is legal, it will be directly converted to the CAD operation identification module. If the data is illegal, it will wait for a certain period of time and then connect to the CAD drawing file for transmission until the data is judged to be legal. If the data is still judged to be illegal after the set time, the transmission fails.

Among them, COM technology, namely Component Object Model, is a set of software component specifications and interface standards developed by Microsoft. It mainly defines how software components interact and communicate with each other, regardless of what programming language these components are implemented in, what operating system they run on, and whether they are in the same process or on different machines in the network. In COM technology, components interact through interfaces. An interface is a series of predefined methods that allow components to provide functions to the outside world without exposing their internal implementation details. COM technology is language-independent and platform-independent, which means that components written in different programming languages can interoperate through COM, and COM components can run on different operating system platforms. This capability makes COM an important technical foundation for realizing software reuse, system integration, and network communication.

CAD, or AutoCAD, is a computer-aided design (CAD) software developed by Autodesk, an American company. It is widely used in the fields of 2D drawing, detailed drawing, design documentation and basic 3D design. The software provides users with a powerful design platform, enabling designers to complete a series of tasks from conceptual design to construction drawing more efficiently.

S2: The CAD operation recognition module pre-processes the frame block to be printed, and obtains the position of the relevant information to be recognized in the frame block to be printed (such as the drawing name, drawing number, drawing size and other position coordinates of the drawing). Generally, the position of the object to be recognized relative to the frame is relatively fixed, and the position information of the object to be recognized in each block of the frame block to be printed is obtained. This information is saved through the data saving module as a proprietary database for this drawing.

The drawing frame block to be printed is a pre-set block with the drawing printing range as the boundary. Different blocks are defined according to the size of the printing range. The block contains the specific range of the object to be identified. Optionally, a Spline object can be used as the range box of the identification object.

S3: The user selects the frame of the drawing to be printed in the current CAD drawing through the user interface module, and obtains the list of frames to be printed in the entire drawing file. The frame name can be used as a block filter during selection, and the selection method can be to scan the entire drawing objects one by one or to select the objects by the user. Regardless of which method is used, the preset frame block name to be printed is preferably used as the frame block selection filter.

The user interface is a platform or interface for users to interact with the system. The purpose of the user interface is to provide an intuitive, easy-to-use, and efficient way for users to understand and operate products or services, thereby obtaining a good experience. As shown in FIG3 , an example of a user interface is provided.

S4: The CAD operation recognition module reads the proprietary database generated by the drawing (generated in step S2) from the data storage module, applies it to each frame block in the list of frames to be printed, finds the object to be identified in the drawing by identifying the position of the object, obtains the relevant information corresponding to each drawing, and obtains the relevant information including but not limited to the drawing name, drawing number, and specific content of the drawing, and then transmits this information back to the CAD operation recognition module through the data transmission conversion module for processing and displaying it to the user interface. The position information of the object to be identified in each block of the frame block to be printed is in the block coordinate system and needs to be converted to the current drawing coordinate system.

S5: The user confirms whether the information is correct and provides the possibility of modifying the relevant information. After confirmation, the printer in the CAD software program matrix is called to output the PDF format files of the printed drawings one by one to the file path where the drawings are located. The present invention can customize the naming method of the file name, and by setting the keyword form, clarify the combination of drawing information identified by the proprietary database such as drawing name, drawing number, and drawing size as the output print file name. The present invention can also output the drawing catalog in the form of a file through the drawing information identified by the proprietary database. The content of the drawing catalog is also the relevant information identified in the drawing. Optionally, the drawing information identified by the proprietary database (generated in step S2) can be sorted in the natural order of the drawing number, and the printed drawing information can be output in excel file format as a drawing catalog.

The above are only specific embodiments of the present invention. It should be pointed out that any changes or substitutions that can be easily thought of by any technician familiar with the field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention, and the rest not described in detail belong to the prior art.
