Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] In this embodiment, the specific steps of the basic data management method for the assembly design of the three-dimensional model are illustrated by taking the tower top suspenders as an example:

[0027] Step 1: Add the type of tower top davit in the type tree, set the name of this type as tower top davit, import a picture as the icon of tower top davit, set the rule string and other basic properties of the tower top davit; figure 1 shown.

[0028] Step 2, define the seed part of the tower top davit, set its label, add an example picture, add a model file, import the associated size table, and set the size specification of the part; for example figure 2 shown.

[0029] Step 3, set the assembly rules of the tower top suspenders, and add custom assembly relationships according to requirements; for example image 3 shown.

Abstract

The invention discloses a basic data management system for three-dimensional model assembly design. The basic data management system comprises a type management module, a seed management module, an assembly rule management module, an attribute management module and a positioning mode management module. The invention also discloses a basic data management method for the three-dimensional model assembly design, and the method comprises the steps: carrying out the selection or building of a new model in a type tree according to the type of a needed three-dimensional model, and setting the basic attributes of the type; setting attributes of the seed parts under the type; setting an assembly rule of the type; setting other attributes of the type; and setting a positioning rule of the type. Themethod has the advantages that a designer does not need to calculate the part size according to the national standard and repeatedly and mechanically set the parameters and attributes of the three-dimensional model, the labor cost is greatly reduced, and the efficiency of three-dimensional model assembly design is improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional model assembly design in mechanical engineering, and more specifically, relates to a basic data management system and method for three-dimensional model assembly design. Background technique [0002] The assembly design workload of complex 3D models in mechanical engineering is very demanding, especially the basic data of the 3D model needs to be set according to national standards and its design parameters should be generated. The design efficiency is low, the error rate is high, and a large number of talents and human resources are required. Very wasteful. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a basic data management system and method for 3D model assembly design with high design efficiency, high accuracy and low maintenance cost. [0004] In order to achieve the above object, technical solution of the present in...
