Description

Batch creation custom labeling method based on CATIA V6 engineering drawing

Technical Field

The invention relates to an engineering icon annotation method, in particular to a batch creation custom annotation method based on CATIA V6 engineering drawings.

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 EKL is native embedded script language of CATIA V6 platform. The use is very flexible and convenient, and the learning cost is relatively low. The user can not only operate through Knowledge engineering tools such as formulas, rules, checks, design tables, knowledge engineering arrays, behaviors and the like which are used conventionally, but also call a large number of Knowledge packets packaged in the Knowledge Package, and the efficiency of design and development can be greatly improved. The CATIA V6 engineering drawing module (Drafting) allows designers to obtain two-dimensional engineering drawings that are fully related to three-dimensional solid models. Native functionality of the CATIA V6 provides simple dimensioning (length, radius, angle, etc.), textbox labeling (which may be custom text content, or may be associated with some attribute), tolerance labeling, and notation labeling.

The labels used in the engineering drawing are a set of reusable geometric figures and labels. In CATIA V6, a 2D part reference (2D Component) or other tag may be used to create a tag template, which is then reused to create the required number of tag instances. After the label instance is created, there is no link between the label instance and the label template. Thus, modifications made to the tag template properties or annotation properties in the tag template are not reflected in the tag instance at the time of creation of the tag instance.

The ship design engineering drawing is taken as an embodiment, and a large number of labels needing to be customized exist in the drawing, as shown in fig. 1. Currently, two methods are commonly used to create such annotations:

the first method comprises the following steps: the label is created in a non-label (label) form, and a text box label, a sketch tool and a combination form are required to be used, so that a great deal of operation time is consumed for designers.

The second method comprises the following steps: the label is created in the form of label (Lable), so that a designer needs to judge the type of a pattern to be labeled firstly, then selects a matched label template from a label (Lable) library and instantiates the label template in an engineering drawing, and finally endows correct labeling content in the instantiated label.

The second method has certain efficiency compared with the first method, but manual operation is still required, and the drawing efficiency is very low due to a large number of repeated operations. It should be noted that the manual labeling method is prone to problems of labeling error, label loss, label missing, and repeated labeling, and thus the design quality is affected. In addition, if the marked content is changed, the marked content cannot be updated in time.

The technical contents disclosed in the prior art patents, such as patent application publication No. CN 111696174A, patent application publication No. CN 114398507A, patent application publication No. CN 114462111A, etc., include: (1) a custom annotation style target that is not in line with the present application; (2) not applicable to ship design engineering drawing examples; (3) failure to implement in CATIA V6.
