Introduction

With the digital transformation of various industries, 3D models have become the core tools for product expression and data transmission.

It is collectively referred to as three-dimensional product data. It not only provides an intuitive and vivid display method for design and manufacturing information, but also helps to improve the content of data.

However, the native formats of design and simulation are often limited by specific software and its implementation mechanism, and the formats are complex and varied.

With the deepening of digital transformation, the demand for product data full life cycle management and application is increasing.

It is no longer limited to the design and simulation stage, but runs through multiple links such as production, marketing, operation and maintenance, and even destruction, showing a significant cross-industry With the characteristics of cross-industry, cross-domain, cross-organization and cross-platform, the demand for interoperability of product data has expanded dramatically. In order to resolve this contradiction, we urgently need A unified 3D product data format that is independent of any specific software to ensure broad versatility in product representation and content data Efficient interoperability.

To this end, this document specifies a 3D product data format based on visualization and lightweight content, with the following characteristics.

- High compression rate. Only the result data of modeling or simulation is retained, and the converted file size is small by using redundancy elimination and compression.

The native format is significantly smaller;

- Support calculation. Use BRep model to store geometric and topological information to better support application requirements such as quantity calculation and assembly;

- Efficient reading and writing. Product data is stored in blocks according to different types and associated through indexes to facilitate random access and efficient computing;

- High security. supports the definition of data access rights;

- Scalability. Supports user-defined data.

The format is designed to support the reuse of product data at multiple stages, from manufacturing/construction, marketing, operation and maintenance to recycling, to fully meet the needs of product data from design to production.

Different roles, such as 3D product data visualization and related applications, include. Use demand.

3D product data visualization application format

1 Scope
