Description

TECHNICAL FIELD

[0001] The application belongs to the field of engineering design drawing, and particularly discloses a method and system for batch generating AutoCAD drawing layout with automatically updated title bar. BACKGROUND

[0002] In the fields of building engineering, civil engineering and mechanical manufacturing, AutoCAD is a general software for engineering design in these industries, but after the completion of graphic drawing by AutoCAD, the process of adding drawing frame, manually filling or modifying drawing title bar information and completing printing of drawings is very tedious, and the following several conventional operations are often used in actual production:

[0003] Method one: without using AutoCAD layout function, all contents are directly drawn in model view, and drawing frame is manually placed, title bar information in each drawing frame such as drawing name, drawing number and printing date is manually written, and the built-in printing prompt window is used to frame the outer line of drawing frame, select printer or plotter, select printing style and print each drawing represented by the drawing frame one by one. This method needs manual operation for printing of each drawing, and the steps are very tedious and the efficiency is very low.

[0004] Method two: model view and layout view are mixedly used, a part of graphic drawing is completed in model view, a default drawing layout page is generated by AutoCAD, one or more drawing frames are manually drawn in the page, title bar information of the drawing frame is manually filled or modified, and viewport linking a certain area in model view is manually placed in the inner line of each drawing frame. This method does not use layout range printing, and still needs to frame each drawing frame range in layout to determine the printing range of each time (each drawing) and manually configure printing parameters in each printing process, so this method is similar to method one, the steps are very tedious and the efficiency is very low.

[0005] Method three, on the basis of method one and method two, using the function of AutoCAD general block, making the frame as a general block, and then using the secondary development technology to write the plug-in of batch printing function, finding the aforementioned frame general block reference object in the model view or layout view, using the program to complete the printing of drawings in batches, and the printing range of each drawing is set by the program as the outer edge line of the frame general block, and all the printing processes use the same printer / drawing instrument and the same printing style. There are many batch printing plug-ins on the market, most of which are developed based on method three. Although this method has certain efficiency improvement, it still has many limitations. First of all, when a project needs to be printed, all the graphic files still need to be opened manually, and the batch printing command needs to be run for each opened graphic file. This process often takes a lot of time. Secondly, this method cannot generate a single virtual printing file at one time, such as a single dwf or a single pdf file. Thirdly, this method uses general blocks to realize the positioning of the drawing printing range, but the title bar information of the drawing still needs to be filled in manually. In actual production process, the content of the drawing and the title bar are modified frequently, and the printing operation after modification is also very frequent. When there are a large number of graphic files in the project, it takes a lot of work and time to open, modify and print each file. Finally, such batch printing plug-ins usually cannot select part of the frame content for printing after scanning all the frames, and the flexibility of selection is not enough, which cannot meet the printing needs of users.

[0040] In order to make the purpose, technical scheme and advantages of the embodiment of the present application more clear, the technical scheme in the embodiment of the present application will be described below in combination with the drawings in the embodiment of the present application, and the described embodiment is a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without making innovative labor are within the protection scope of the present application.

[0041] In combination with the drawings in the specification, an embodiment of the method for batch generating the AutoCAD drawing layout with automatically updated title bar is as follows: the specific steps of the technical scheme are as follows:

[0042] A drawing frame dynamic block containing a title bar is made in AutoCAD, and the dynamic block contains two basic contents: frame inner and outer lines and the title bar. Taking the water conservancy and hydropower engineering industry as an example, the dynamic block style made is as shown in Figure 1 , wherein the blue annotations are the dynamic block parameters used; the query parameter list made is as shown in Figure 2 ; one of the title bars made is as shown in Figure 3 , wherein the red circled text is the "block attribute", which is also the dynamic field mentioned in the present application, and these attributes all have hyperlink properties, such as the "project name 1" which is linked to the current drawing set self-defined property "project name 1" (as shown in Figure 4 ), so that when the value of "project name 1" in the drawing set is modified, the value of "project name 1" of the drawing frame block in the drawing layout will also be automatically updated and displayed; other block attributes in the title bar are similar to be made, and will not be described herein.

[0043] By using the AutoCAD plug-in development technology, including but not limited to using AutoLisp, objecARX,.net API, Javascript API and other tools, a functional plug-in is developed, and the plug-in is loaded in AutoCAD by using plug-in loading commands such as appload, netload, script and the like.

[0044] In the model view drawing interface of AutoCAD, according to actual needs, one or more dynamic blocks with any scaling ratio and any rotation angle are inserted. For the convenience of illustration, the application inserts four picture frame dynamic blocks made in the S1 step in the AutoCAD model view, and selects the sizes of the picture frames as A3, A2, A1 and A0 respectively, adjusts the global scale of the dynamic blocks to 100, and sets the rotation angles of the A3, A2 and A1 dynamic blocks to 15° to match the contents to be printed into pictures, and after completion, as shown in Figure 5 .

[0045] After loading the plug-in developed in the foregoing steps, the command of batch generating picture layouts can be executed, according to the command prompt, after selecting any one of the picture frame dynamic blocks, the plug-in program automatically searches all dynamic blocks of the same type in the model view, obtains four picture frame dynamic block reference objects, finds the page setting parameters matching the picture frame dynamic block map in the preset page setting table (as shown in Figure 6 ), and automatically generates four picture layouts according to these parameters, wherein each picture layout corresponds to one page of picture to be printed / published in the model view. After opening one of the generated picture layouts, the software interface is as shown in Figure 7 . The page setting interface of the picture layout is opened, as shown in Figure 8 , it can be seen that the printer / drawing instrument name, picture size and print style table of the picture layout are consistent with the A3 size shown in Figure 6 . And the print area (print range) has been set to “layout”, which indicates that the picture layout can already be executed for automatic printing / publishing.

[0046] Using the AutoCAD self-function command, a new picture set is created, and all custom properties required by the dynamic block title bar attribute are added to the picture set, and then the custom properties are assigned values. A typical picture set custom property example is shown in Figure 9 . Using the AutoCAD self-function command, the picture layout is selected and added to the newly created picture set, and AutoCAD software will automatically update the title bar information in the picture layout frame. The frame title bar of the picture layout before and after being added to the picture set is as shown in Figure 10 . Before being added to the picture set, “####” in the title bar indicates that it is not linked to the corresponding property value, and after being added to the picture set, the dynamic block attribute in the title bar is updated to the corresponding property value in the picture set. If the picture set properties need to be modified later, the picture set manager of AutoCAD can be used to modify the custom property values, and after modification, the frame title bar in the picture layout will be automatically updated.

[0047] Using the built-in function of AutoCAD's drawing set, the drawing layout in it is added. All the drawing layouts added in the drawing set are displayed as drawing lists, and one or more of these list items can be selected at the same time. The selected drawing layout is directly published by the drawing set function to complete the batch printing / publishing of drawings.
