It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method for processing the DXF file information can be applied to an application environment diagram shown in figure 1, a user classifies and divides a plurality of graphic elements in a DXF file of a finished building process drawing, then uploads the DXF drawing after the classification processing to a terminal, the terminal can be a client terminal and a service terminal, the terminal is used for reading the graphic element information of the DXF drawing, when the terminal receives the DXF file, the terminal starts to read the drawing information of the DXF file (the drawing information comprises the attribute information and the graphic element information of a frame block, and the graphic element information comprises a plurality of tables), then the graphic element information is divided into a plurality of areas according to the attribute information of the frame block and the size data of a preset frame block, then the graphic element information of each area is read in a circulating mode, the graphic element information of each area is classified to obtain classification data, and further, the data belonging to the same table in the classification data are collected, and preserving the sequence among the data to obtain the integrated primitive information of each area.
The client terminal 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices; the service terminal 104 may be implemented as an independent service terminal or a service terminal cluster composed of a plurality of service terminals. Wherein the data information can be transmitted between the client terminal and the service terminal.
In one embodiment, as shown in fig. 2, a DXF file information processing method is provided, which is described by taking an example that the method is applied to a service terminal, and includes the following steps:
step S200, when the DXF file is received, drawing information of the DXF file is read, wherein the drawing information comprises attribute information and graphic element information of the graphic block, and the graphic element information comprises a plurality of tables.
The DXF file is an AutoCAD (Drawing Exchange Format or Drawing Exchange Format) Drawing Exchange file, and a complete DXF file structure comprises six file segments and an end of Edge (EOF) flag. The six file segments include: the head segment, the class segment, the table segment, the block segment, the entity segment and the object segment respectively store the version number and the system variable, the class information of the system definition, the system table information, the graphic block information and all the non-geometric entity information of other graphic files (the file segments are defined in the drawing design stage). In this embodiment, the primitive information includes a text, multiple texts, a point, a straight line segment, a curve, multiple line segments, an arc, an elliptic arc, an ellipse, a circle, a B-spline curve, a combined block of the primitive, a layer attribute, and a table composed of multiple straight line segments and multiple pieces of text information, where the frame block refers to a rectangular box marked in the DXF file by a user, and reading the drawing information of the DXF file refers to caching all the primitive information of the drawing, including information such as a position coordinate, a length, a color, a layer, and a name.
In step S400, the primitive information is divided into a plurality of regions according to the attribute information of the frame block and the size data of the preset frame block.
In practical application, a drawing designer classifies a plurality of single drawings in a DXF file, and uses a rectangular box (a drawing block) to divide the primitive information belonging to the same category into the same area, thereby completing area division of all the primitive information. Specifically, the AutoCAD system provides an absolute coordinate system, namely a world coordinate system, coordinates of the world coordinate system cannot be changed, but a drawing designer can define a plurality of coordinates according to the world coordinate system, so that the drawing design is facilitated. In this embodiment, a reference area of the DXF drawing is determined by using a relative coordinate system, and then a range area is set according to a reference point of a frame block (a frame block of an area is marked by manual instruction software, that is, a rectangular frame, each frame is marked, and the size of each defined rectangular frame is the same), so that area division is completed for all primitive information of the DXF file. It will be appreciated that in other embodiments, the frame blocks may or may not be the same size.
And step S600, circularly reading the primitive information of each area, and classifying the primitive information of each area to obtain classified data.
After the area division of the primitive information is completed, firstly, the primitive information of a single area can be circularly read by adopting a recursive loop algorithm until the primitive information of all the areas is completely read. And then obtaining the coordinates of the primitive information of the single area, analyzing the primitive information of each area according to the coordinates of the primitive information, and classifying the primitive information of each area according to the coordinates of the primitive information and the reference origin coordinates of the frame block where the primitive information is located to obtain classified data. The classification processing includes marking the picture frame blocks corresponding to the read graphic element information. It is understood that in other embodiments, the data reading mode can be other data extraction algorithms.
Step S800, collecting the data belonging to the same table in the classification data, and keeping the sequence among the data to obtain the integrated primitive information of each area.
In practical application, each table in the primitive information comprises attributes of header names, after the primitive information of all the areas is classified, the primitive information is grouped according to the attributes of the header names, then the data with the same header names are collected together, and the original sequence among the data in the same table is kept, so that the integrated primitive information of each area is obtained after the data in all the tables are extracted.
According to the DXF file information processing method, the read primitive information in the DXF file is divided into a plurality of areas through the attribute information of the picture frame blocks and the size data of the preset picture frame blocks, the primitive information of the complex drawing data can be extracted by taking the areas as units, the reading efficiency of the primitive information is improved, the primitive information is classified, the error rate of data reading can be reduced, in addition, the obtained classified data is further subjected to collection processing, in conclusion, the area division, the classification processing and the collection processing are carried out on the primitive information based on the scheme, and therefore effective information management on the information in the drawing can be achieved.
As shown in fig. 3, in one embodiment, dividing the meta information into a plurality of areas according to the attribute information of the frame block includes: step S420, counting the number of the frame blocks, and acquiring coordinate values of a reference origin in the attribute information of the frame blocks, wherein the reference origin is an offset coordinate origin relative to the world coordinate system origin of the frame blocks; dividing the primitive information into a plurality of areas according to the coordinate value of the reference origin and the preset picture frame block size data, and adding marks to each divided area, wherein the number of the areas is equal to the number of the picture frame blocks obtained through statistics.
The attribute information of the frame block includes coordinate values of a reference origin of the frame block, and the size data of the frame block is set in advance as known data. Since the Area of the DXF drawing to be read is determined by the number of frame blocks (divided manually) inside the drawing itself, when the content of the DXF drawing is read, the number of frame blocks is counted by itself, then coordinate values of the reference origin of each frame block are obtained, as shown in the drawing frame diagram of fig. 4, the reference origin is an offset coordinate origin from the world coordinate system origin, the reference point is located at the lower left corner of each frame block, then all primitive information is divided into a plurality of areas according to the preset size data of the frame block, i.e., the size of the length and the width, and the size of the reference origin and the size of the length and the width of the frame block, and marks are added to each Area while dividing the Area, for example, the marks may be Area01, Area02, Area03 …, and the number of the divided areas is equal to the number of the counted frame blocks. It is understood that the manner in which the regions are marked is merely an example, and in other embodiments, the manner in which the regions are marked may be other manners. In the embodiment, a drawing designer divides the area by designing the relative coordinate system through the world coordinate system, so that the division of the primitive data is facilitated.
In one embodiment, cyclically reading the primitive information of each zone, and classifying the primitive information of each zone includes: and step S620, circularly reading the primitive information of each area by adopting a recursive circular algorithm, obtaining the coordinate value of each primitive information, filing and classifying the primitive information of each area according to the coordinate value of each primitive information, the coordinate value of the reference origin and the preset data of the sizes of the picture frames to obtain classified data, wherein the classified data carries the mark of the area to which the classified data belongs.
After the primitive information is divided into regions, the primitive information in each region is also disordered, so that the primitive information in each region needs to be classified and archived. Specifically, firstly, taking a single area as a unit, sequentially reading the content of the single area by adopting a recursive cyclic algorithm, then obtaining data information for circularly sorting the areas, namely obtaining coordinate values of primitive information in the areas, filing and classifying each primitive information in the same area according to the coordinate values of the primitive information, the coordinate values of a reference origin of a frame block and preset size data of the frame block, filing and classifying the primitive information in the area, and filing the primitive information in the area to obtain classified data, in the classifying process, identifying a mark of each read area (frame block), and adding an area mark to each primitive information in the area for marking the area from which the data of the primitive information comes. In this embodiment, by filing and classifying the primitive information in each area, it is convenient for the follow-up manual problem troubleshooting and data checking.
In one embodiment, the method further comprises the following steps: when reading that a certain area contains a plurality of tables, adding a mark index for the primitive information of the area, wherein the mark index is used for distinguishing the primitive information of other areas.
After the division of the areas of the primitive information is completed, the primitive information content of a single area is much simpler compared with the whole drawing, the primitive information of each area can be sequentially read by adopting a recursive loop algorithm, in the process of circularly reading the primitive information of each area of the area, when a plurality of table contents are still nested in a certain area, the area is further divided by adopting a recursive mode, and an index mark is added to the data in the area. In this embodiment, the recursive loop algorithm may also be considered to read the contents of multiple tables. By adding a mark index to table data of an area including a plurality of tables, data in the table can be distinguished from primitive information of other areas.
In one embodiment, the archiving and classifying the primitive information of each area according to the coordinate value of each primitive information, the coordinate value of the reference origin, and the preset block size data comprises: and calculating the difference value between the coordinate value of each primitive information and the coordinate value of the reference origin, comparing the size relation between the difference value and the preset drawing frame block size data, and filing and classifying the primitive information of each area according to the size relation and the preset drawing specification standard.
In this embodiment, the classification and archiving of the primitive information in each area is performed according to the difference range between the coordinate value of the primitive information itself and the reference origin of the frame block. Specifically, as in the previous embodiment, the drawing area of the architectural art drawing is scribedThe world coordinates of the frame blocks of the drawing content are taken as reference, the reference origin is located at the lower left corner of the frame blocks, as shown in a single-region coordinate schematic diagram shown in fig. 5, the frame blocks are rectangular regions in a two-dimensional coordinate system shown in fig. 5, the difference value between the coordinate value of each primitive information in the rectangular regions and the coordinate value of the reference origin is calculated, the size relationship between the difference value and the preset frame block size data is compared, and the primitive information of each region is filed and classified according to the preset drawing specification standard according to the size relationship. For example, the Area01 is set to have a width M, a height N, and the coordinates of the primitive information A in the Area01 are set to be (X)1,Y1) Reference origin O of picture frame block1Is (X)0,Y0) Then the primitive information A and the frame block reference origin O1The coordinate difference of (a) is: Δ X ═ X1-X0、ΔY＝Y1-Y0If Δ X is less than or equal to M and Δ Y is less than or equal to N, determining that the primitive information a is located in the Area01, and dividing the primitive information a into the Area01, thereby completing classification and archiving of all primitive information, and simultaneously classifying and archiving the primitive information according to a preset drawing specification standard, for example, labeling data to two bits after decimal point. In this embodiment, the classification filing mode may be to extract all the integrated classification data into a form to obtain DXF drawing form data. It can be understood that, in other embodiments, after the area division is completed, the primitive information is integrated according to the difference between the primitive information coordinates and the reference origin, so that the method is simple, convenient and effective, and the error rate in the later data export process can be reduced.
As shown in fig. 3, in one embodiment, after obtaining the primitive information of each integrated area, the method further includes: and step S900, displaying the integrated primitive information of each area.
As described in the foregoing embodiment, after obtaining the integrated primitive information, the integrated primitive information of each area is displayed, specifically, the displaying of the integrated primitive information of each area is represented by sending a display instruction to the client terminal 102 at the service terminal 104, and after receiving the display instruction, the client terminal 102 displays the DXF drawing table data obtained after integrating the primitive information on the screen, where the table data may refer to fig. 6, where fig. 6 shows a part of the content of the table data obtained after reading the frame content of a single area, and a user can view and check the integrated primitive data on the display interface. In this embodiment, by displaying the integrated primitive information of each region, a user can check and check the primitive information conveniently.
As shown in fig. 3, in one embodiment, after obtaining the primitive information of each integrated area, the method further includes: step S950, storing the integrated primitive information of each region in a text file, or storing the integrated primitive information of each region in a table form to a preset database.
In this embodiment, the text file is a CSV (Comma-Separated Values) file, which is sometimes also referred to as a character separation value because the separation character may not be a Comma, and the file stores table data (numbers and text) in a plain text form. After the primitive information of each area is integrated, the integrated drawing data can be exported for use in order to facilitate subsequent use of the integrated drawing data. In this embodiment, the integrated primitive information is saved by using a text file, or the integrated primitive information is saved in a preset database, such as MySQL, Oracle or other databases. In this embodiment, the text file is a CSV (Comma-Separated Values) file, which is sometimes also referred to as a character separation value because the separation character may not be a Comma, and the file stores table data (numbers and text) in a plain text form. In the embodiment, the integrated primitive information is stored persistently in a file CSV file or database mode, so that the data of the integrated drawing can be checked and used anytime and anywhere.
