Example Embodiment

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0029] like figure 1 As shown, a template-based engineering drawing generation method; including the following steps:

[0030] 1) Construction of drawing template

[0031] Through CAD composition software, use the basic composition unit command to draw a three-dimensional diagram representing a single type and mark the three-dimensional diagram. The single type here, such as triangle, rectangle, rectangle with an arc edge, etc., and then in the form of a CAD file Save to disk as a CAD drawing template for recall;

[0032] Or select the drawing files used in previous projects, and save these drawing files to the disk in the form of CAD drawing templates; a drawing file represents the engineering drawings required for a type of workpiece, and generally the name of the workpiece type that needs to us...

Abstract

An engineering drawing generation method based on a template comprises the steps that firstly, the CAD drawing template is constructed; secondly, modeling is conducted on all entities on rhinoceros software, then selection and classification are conducted on all the entities which are subjected to modeling, representative models of each type of model are automatically selected and configured, and the representative models obtained after configuration are picked up and input into a system; thirdly, a CAD file is opened; fourthly, the file which is modeled and configured through the rhinoceros software in the second step is converted into a transfer file, the file path of the file is input into the system, and the system inserts the file path into a model space of the CAD file newly built in the third step; fifthly, a picture frame built-in block is inserted; sixthly, picture frame data is inserted; seventhly, the CAD drawing template is inserted; eighthly, attached table data is inserted, each class of workpiece parameter data obtained when all the entities are selected in the step (4-1) is input in a tree data form, and a data table corresponding to the drawing is generated under the drawing. The working intensity of workers is reduced, and constraints of production time are broken.

Description

technical field [0001] The invention relates to the method field of parameter modeling, in particular to a template-based engineering drawing generation method. Background technique [0002] In the manufacturing industry, engineering drawings are a necessary production link for workers to produce workpieces. The quality and speed of engineering drawings often determine the efficiency and effectiveness of production. The traditional engineering drawing generation is mainly to manually carry out 3D modeling and labeling of the production workpiece in the model space of the CAD software, then switch to the CAD layout space to construct the drawing frame and construct the viewport, so that the viewport corresponds to the model space model, and finally Layout space engineering drawings for printing. However, manual use of CAD software to build models and mark them will cause a large workload during production, and the accumulated engineering drawings will not be reused, which is...
