Detailed Description
The following describes the embodiments of the present invention in detail with reference to examples, but they are not to be construed as limiting the invention. While at the same time becoming clearer and more readily understood by way of illustration of the advantages of the present invention.
The CAD drawing file batch processing system shown in FIG. 1 comprises: the data transmission conversion module is used for carrying out data transmission through the operating system and the CAD software program, and the transmitted data is converted into a data form which can be identified by the operating system through the module so as to enable the operating system and the CAD software program to be mutually identified; the CAD operation identification module is used for processing operation instructions of CAD in the program, including object identification, related attribute acquisition, printing operation and logic operation; the data storage module is used for storing the internal operation parameters and related setting parameters of the device and recording predefined frame block information; and the user interface module is used for the interaction platform of the user and the program interface.
The CAD drawing file batch processing method as shown in FIG. 2 comprises the following steps:
S1: in the data transmission conversion module, CAD drawing files are linked through a COM technology to form an effective data transmission channel, after the channel is established, all blocks in a block manager in the CAD file are obtained, the blocks are matched with a program preset drawing block to be printed (the block name attribute can be passed), and the printing drawing block actually used in the CAD drawing file is obtained through filtering. It should be noted that, the data transmitted by these programs and CAD files are all converted by the data transmission conversion module. The data conversion is because the operating system cannot identify the internal data structure of the program by applying the COM technology, and the data needs to be converted into a data form which can be identified by the system.
In the CAD operation recognition module, the data transmission conversion module and the CAD drawing file are not as fast as possible to form effective transmission because the program operation is too fast, so that the data transmission conversion module is required to judge whether the data is legal or not, if the data is legal, the data is directly converted to the CAD operation recognition module, if the data is illegal, the data is connected with the CAD drawing file for transmission after waiting for corresponding time until the data is judged to be legal, and if the data is still judged to be illegal after the set time is exceeded, the transmission is failed.
The COM technology, component object model (Component Object Model), is a set of software component specifications and interface standards developed by microsoft corporation. It mainly defines how the software components interact and communicate with each other, regardless of the programming language in which they are implemented, on what operating system they run, and whether they are on different machines in the same process or network. In COM technology, components interact through interfaces. An interface is a series of predefined methods so that a component can provide functionality to the outside world without exposing its internal implementation details. COM technology has language independence and platform independence, meaning components written in different programming languages can interoperate through COM implementations, and COM components can run on different operating system platforms. This capability makes COM an important technological base for achieving software reuse, system integration, and network communication.
CAD, autoCAD, is a piece of computer-aided design (CAD) software developed by Autodesk, inc. in the United states, and is widely used in the fields of two-dimensional drawing, detailed drawing, design documentation, basic three-dimensional design, etc. The software provides a powerful design platform for users, enabling designers to more efficiently complete a series of tasks from conceptual design to construction drawing.
S2: the CAD operation identification module preprocesses the frame blocks to be printed, obtains the positions (such as drawing names, drawing numbers, drawing frame and the like coordinates of drawings) of relevant information to be identified in the frame blocks to be printed, generally, the positions of objects to be identified relative to the frames are relatively fixed, the position information of the objects to be identified in each block in the frame blocks to be printed is obtained, and the information is stored through the data storage module to be used as a proprietary database of the drawing.
The to-be-printed frame blocks are preset, blocks with drawing printing ranges as boundaries are defined according to different printing ranges, the blocks contain specific ranges of objects to be identified, and optionally, a line object can be used as a range frame of the identification object.
S3: and the user selects a frame of the to-be-processed printing drawing in the CAD drawing through the user interface module, and a list of the to-be-printed frames in the full-drawing paper file is obtained. The frame name can be used as a block filter when selecting, and the selecting mode can be a mode of scanning full-image objects one by one or selecting objects by a user frame, and no matter what mode is adopted, the preset frame block name to be printed is preferably adopted as the frame block selecting filter.
The user interface is a platform or interface for the user to interact with the system. The purpose of the user interface is to provide an intuitive, easy-to-use, efficient way for the user to understand and manipulate the product or service, thereby obtaining a good experience. As shown in fig. 3, an example of a user interface is provided.
S4: the CAD operation identification module reads the generated special database (generated in step S2) of the drawing from the data storage module, applies the special database to each frame block in the to-be-printed frame list, finds out the object needing to be identified in the drawing through identifying the position of the object, acquires the relevant information corresponding to each drawing, acquires the relevant information including but not limited to the drawing name, drawing number and specific content of the drawing, and then transmits the information to the CAD operation identification module for processing through the data transmission conversion module and displays the information to the user interface. The position information of the object to be identified in each block in the frame block to be printed is in an intra-block coordinate system and is required to be converted into a current drawing coordinate system.
S5: the user confirms whether the information is correct and provides the possibility to modify the relevant information. And after confirming the error, calling a printer in the CAD software program parent body, and outputting PDF format files of the printing drawings one by one to the file path where the drawings are located. The invention can define the naming mode of the file name by self, and define the combination mode of drawing information identified by the proprietary databases such as drawing names, drawing numbers, drawings and the like by setting the keyword form, and the combination mode is used as the output printing file name.
