From AC to STP file format
AC format files are file formats used for 3D model data storage, mainly used by AC3D software.
AC files use plain text format to store data of 3D models. The file content includes information such as vertices, surfaces, and materials.
Each .ac file can contain multiple objects, each with its own vertex and face definitions. With this structured text format, .ac files can effectively describe complex 3D models.
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.
