Batch sequential printing method and device for CAD drawings

Abstract

The invention discloses a method for CAD drawing batch printing in sequence. The method comprises steps: S01, starting AutoCAD software, connecting the software with a printing device; S02, reading a printing object; S03, establishing a printing sequence array; S04, setting a drawing format; S05, starting the printing device to print. The invention also discloses a device for CAD drawing batch printing in sequence. The device comprises a file reading module, a printing sequence processing module, a drawing format setting module, and a printing device. The file reading module is used to read a printing object. The printing sequence processing module is used to establish a printing sequence array. The drawing format setting module is used to read drawing file primitives and a drawing list file, to obtain printing drawing format setting. The printing device is used to print each CAD drawing in sequence according to the printing drawing format setting. The method and the device for CAD drawing printing are advantaged in that operation is simple, batch printing of the CAD drawings in sequence is realized, and printing efficiency is improved.

Description

technical field [0001] The invention mainly relates to the technical field of printing, in particular to a batch sequential printing method and device for CAD drawings. Background technique [0002] Based on the advantages of AutoCAD, such as high efficiency, accuracy, and easy management, most design industries currently use AutoCAD to draw engineering drawings, and the number of engineering drawings in many industries is hundreds or thousands. However, due to the characteristics of the software itself, traditional CAD The printing of drawings (output as paper documents or other format files) can only be done manually one by one, not batch, continuous, automatic printing, let alone batch printing in the specified order. Among them, printing a single drawing, the main steps are as follows: [0003] (1) Open the drawing file (it takes a lot of time to search when there are many files in the drawing folder); [0004] (2) Select the printing device; [0005] (3) Select the p...

AI Technical Summary

Problems solved by technology

Even if some CAD plug-ins can automatically set the printing, they cannot print in the order of the catalog. After the drawing is printed, the designer must manually organize the drawing, which will waste a lot of time for the designer.

[0014] 2. It is easy to have the problem of underplaying, missing and replaying

[0015] There are a lot of engineering drawings in many industries, and the corresponding folders are also large, which makes it time-consuming to find and open drawing files, and it is easy to have problems of under-typing, missing, and re-typing

[0016] 3. Restrict design efficiency and affect design quality

[0019] 1. The frame recognition (that is, to determine the printing boundary) ability is poor, and it cannot recognize non-standard frame (not a block, or there is an error between the border size of the frame and the size of the standard drawing)

[0020] 2. The identification method is single, and the printing efficiency is low; at present, these small plug-in recognition frame either recognize the block frame, or read the coordinates of the maximum boundary point. In comparison, the first method is faster but adapts to the range It is very small, and it cannot be recognized when the frame is not a standard block; the second type has a wide range of adaptation, but the reading speed is very slow, because it is necessary to read the endpoint coordinates of many primitives, and then compare them one by one to determine the maximum boundary

[0021] 3. The drawing size cannot be automatically configured. For a set of engineering drawings, each drawing file is not necessarily the same. For example, the general assembly may be A0, and the small parts may be A4. The current program is based on the unified drawing set before sending the printing command. When a set of engineering drawings contains multiple drawing sizes, it is necessary to distinguish the size of each drawing file, and then print in batches, the printing efficiency is low

[0022] 4. It cannot be printed in the order of the catalog. After the drawings are printed, the designer must manually organize the drawings, especially when there are a lot of drawings, which will waste a lot of time for the designer
