Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 1 As shown, a 3D part model version comparison system based on Creo software includes a system main control module, a source model reading module, a comparison model reading module, a model comparison module and a visualization module. Each module is described in detail below:

[0037] (1) System main control module

[0038] The main control module of the system is the user-system interaction module, which sends the source model file storage path information, the comparison model file storage path information and the comparison information type input by the user to the source model reading module and the comparison model reading module respectively , and at the same time, send the comparison information type and the comparison control instruction input by the user to the model comparison module. The source model file ...

Abstract

The invention discloses a three-dimensional-part-model version comparison system based on Creo software. The system includes a system main-control module, a source-model reading module, a comparison-model reading module, a model comparison module and a visualization module. The system main-control module is used for providing comparison information types and source-model and comparison-model storage paths, and sending control instructions and the like. The source-model and comparison-model reading modules read corresponding information of a source model and a comparison model, and send the same to the model comparison module. The model comparison module adopts a method of traversal to compare the corresponding information of the source model and the comparison model piece by piece according to a comparison information type. The visualization module adopts row-by-row pairing lists or a manner of three-dimensional visualization to carry out result difference display according to the comparison information type. According to the system, comparison efficiency of different design versions of three-dimensional rocket part models is improved, manpower operation burdens and error probability in a traditional-manual-manner comparison process are reduced, and a product development cycle is shortened.

Description

technical field [0001] The invention relates to a three-dimensional part model version comparison system based on Creo software, which belongs to the field of digital design and system simulation of aerospace products. Background technique [0002] At present, when designers use Creo software to carry out 3D model design of launch vehicle structural parts, they often need to compare the information of the current version of the 3D model (comparison model) with the information of the previous version of the 3D model (source model) to determine the changes. The information is notified to downstream manufacturers in a timely manner. Due to the long design cycle of rocket structural parts and many changes, the traditional manual method of comparing and checking item by item requires a lot of repetitive work, which requires a lot of time and energy, and is easy to miss items, resulting in low efficiency and error-prone problems. , which directly affects the product design cycle....
