Description

Engineering drawing batch printing method based on CATIA V6

Technical Field

The invention relates to a CATIA V6-based engineering drawing batch printing method, and belongs to the field of engineering drawing printing.

Background

The CATIA V6 is CAD/CAE/CAM integrated software released by Dasuo corporation, and is widely applied in aerospace, automobile manufacturing, ship building, machinery manufacturing, electronic/electric appliances, mechanical design and consumer goods industries.

The CATIA engineering drawing module (Drafting) enables designers to obtain a two-dimensional engineering drawing completely related to the three-dimensional solid model, and the engineering drawing can also be sent to a printer to be printed. An engineering Drawing is called a Drawing, a plurality of Sheet nodes are divided under a Drawing general node, the Sheet nodes are equivalent to a piece of white paper and contain various views, and generally the Sheet nodes provide layout ranges for the views, as shown in fig. 1. At present, in engineering application, a two-dimensional engineering drawing is indispensable, and as an important technical document material, the engineering drawing must meet certain specifications and standards. The drawing frame is an indispensable drawing element in the engineering drawing and contains a great deal of engineering information such as drawing size, designer, proofreader, product name, proportion and the like.

CAA is a powerful tool for daxol product expansion and secondary development by customers. The CAA is realized by providing a Rapid Application Development Environment (RADE) and different API interface programs. RADE is a visual, integrated development environment that provides a complete set of programming tools. In fact, RADE takes Visual Studio as a vector, and the development tool of CAA is increased in the C + + environment. The API provides methods, tools, and interfaces for manipulating various objects. The user can extend the CATIA V6 by developing a CAA plug-in of the user.

The 2D part is a set of reusable geometric figures and labels. This part is located in the drawing and can be edited as a view. The 2D part may be instantiated multiple times and each instance may provide a particular direction, position, and scale.

The CATIA native print function interface is shown in FIG. 3. Its print area selection provides 4 ways: (1) printing the complete Sheet; (2) print screen visible Sheet range; (3) printing the selected area; and (4) printing the predefined area. It can be seen that the native function does not provide a batch printing function, and printing of only a single area can be performed. Often, dozens or even hundreds of drawings in the engineering drawings need to be printed, and the output efficiency is very low due to a large number of repeated operations. In addition, if a single printing method is adopted, the problems of error printing range, less printing, missing printing and repeated printing are easy to occur. Due to low plotting efficiency, under the condition of a certain design period, the time for other design links is relatively short, and the design quality is influenced.

The printing range of the engineering drawing is often in units of frames, but the CATIA native function frames are in the range of Sheet boundaries, namely one Sheet is an engineering drawing. In addition, in the actual drawing process, multiple views (such as a cut-away View, a detail View and the like) exist in one Sheet, and all the views need respective frames, so that multiple frames need to exist in one Sheet. As shown in fig. 4, it can be seen that the frame generation function of the native function cannot meet the actual printing requirement of the enterprise.

The currently published patent applications and papers on CATIA technology are:

the invention patent application with the publication number of CN 101364172A discloses an implementation method for automatically generating an engineering drawing frame in Catia V5 software. As the CATIA V6 and the CATIA V5 complete the upgrade, replacement, and deletion of the original functions on the engineering drawing module, the technical method disclosed in the patent application falls behind, and a user cannot realize the generation of a drawing frame in the CATIA V6 by using the patent method.

In the document, "engineering drawing jigsaw printing management system based on CATIA", all views in a drawing are fully spliced in a Sheet according to a certain rule by a CAA means, and batch printing is not realized or single Sheet printing is realized.

The native function method used in the literature "engineering drawing frame, title bar and detail bar fast generation technology based on CATIA" is used for generating the drawing frame, the limitation of Sheet on the drawing frame is not broken through, and batch printing in one Sheet cannot be realized.
