Description

STEP (Standard for the Exchange of Product model data) is an international standard used for data exchange in the fields of computer-aided design (CAD) and computer-aided manufacturing (CAM). It defines a universal data format for describing and exchanging product model data.

STEP files adopt a neutral, platform independent representation method that allows for data exchange across different CAD software and systems. It uses an entity based data model, as well as a unified data structure and semantic rules, to ensure data consistency and reliability.

STEP files can contain rich product model information, such as geometric shape, topological relationships, material properties, assembly structure, dimensions and tolerances, and process information. It supports multiple geometric types of representations, including points, lines, curves, surfaces, volumes, etc., while also storing other non geometric attributes such as color, mass, material properties, etc.

There are many advantages to using STEP format for data exchange. Firstly, it allows seamless data interoperability between different CAD software, thereby avoiding issues of data conversion and information loss. Secondly, STEP files are text based, have good readability, and are easy to view and edit. In addition, as STEP is an international standard, it can promote global data exchange and cooperation.

In the fields of industrial manufacturing and engineering, STEP is widely used in product design, process planning, CNC machining, assembly analysis, virtual prototyping, and other links. It provides a standardized data exchange method, promotes the integration and collaborative work of design and manufacturing processes, and improves production efficiency and quality.

Description

The 3MF file is a modern 3D file format designed specifically for 3D printable models (additive manufacturing). It aims to be the successor to the popular traditional STL format (also a common format in 3D printing) to overcome its limitations.

The 3MF file format is based on XML and is compressed using standard Zip file compression to generate small, easy-to-transfer files. The format supports 3D meshes as well as all related materials and textures contained in the Zip file.
