The STEP format is a neutral file format used for the exchange of data in the field of CAD. It can contain data, such as 3D geometry, product structure, attributes, tolerances, and materials.
Below you can find all the specific types of STEP files that CAD Exchanger supports:
AP203 focuses on mechanical design. It is used to exchange 3D models and associated information for product design and manufacturing processes.
Also known as the Automotive Design Standards, AP214 is used in the automotive industry. It includes additional features to represent complex assemblies and automotive-specific information.
AP242 is an advanced STEP version that supports the exchange of product information throughout the product lifecycle, including manufacturing, assembly, and maintenance.

Since STEP is a neutral file format, it is not tied to any specific CAD software vendor. Almost any software that works with CAD data, and many programs that work with 3D data, can read or write this format.
STEP files are capable of representing complex 3D geometry, including curves, surfaces, and solids. They also store additional information, such as product structure, attributes, and metadata. This ensures that the integrity of the design is maintained during the exchange process, reducing the risk of data loss or conversion errors.
STEP files are widely recognized as a stable and reliable format for long-term data archiving. Their standardization ensures that the files will remain accessible and usable in the future.
Due to their comprehensive nature, STEP files tend to contain a large amount of data, resulting in larger file sizes compared to other file formats. This can pose challenges when it comes to storage, sharing, and transferring files, particularly in cases where limited storage space or bandwidth is a concern.
The larger file sizes can also impact processing and loading times, especially when dealing with complex assemblies or intricate geometries. It may take longer to open, potentially affecting productivity.
The majority of STEP files are written as text files. While it allows for human readability and easy interpretation, it can introduce potential round-off errors in numerical values. These rounding errors may be negligible in most cases, but they can accumulate and impact the accuracy of the model, especially in situations where high precision is crucial.P
STEP files offer interoperability, preserve geometry and associated data, are platform-independent, and are suitable for long-term archiving.
To open this file, you will need a compatible software application, for example, CAD Exchanger Lab. Launch the software and navigate to the 'New file' option. Browse your computer's directories and locate the STEP file you want to open. Then select the file and click "Open". Once the import process is complete, the file should be loaded into the software, allowing you to view and interact with the 3D model and associated data.
Yes, STEP files are widely supported by various CAD software applications. They are designed to facilitate interoperability between different programs. See the full list in the 'STEP format is supported by' section.
The history of this format dates back to the late 1970s when the need for a standardized method of exchanging product data between various CAD systems became apparent. To address this challenge, the International Organization for Standardization formed a committee, ISO TC 184/SC 4, dedicated to developing a universal format.
After years of collaborative effort from experts and industry stakeholders, the first version of the STEP standard, known as AP203, was released in 1994. It aimed to enable the exchange of data for mechanical and electrical designs. Over time, additional versions of the STEP standard were introduced, such as AP214 for automotive design and AP242 for complete product lifecycle information. These versions expanded the capabilities of STEP, accommodating various industry requirements and advancements in technology.
Today, the STEP file format is widely adopted and recognized as a reliable means of exchanging 3D models and associated data between different CAD systems. It has streamlined collaboration, enhanced interoperability, and improved efficiency across industries like automotive, aerospace, and manufacturing.
The FBX format, also known as FilmBox, is a flexible file format that finds extensive use in the entertainment industry for storing 3D models, animations, and associated digital assets. Created by Autodesk, it is commonly employed in video games, movies, and VR applications. FBX files act as comprehensive repositories, preserving essential details such as 3D shapes, textures, animations, and more.
CAD Exchanger can import any FBX files and export FBX files of version 7.2, 7.4, and 7.5 in Binary and ASCII format. Such support includes:

One of the major advantages of this format is its versatility and compatibility. FBX files can be easily shared and utilized across various softwares, making it convenient for collaboration between designers and game developers. FBX guarantees effortless transfer and utilization of 3D models and animations across diverse software environments.
FBX files store a wide range of information related to 3D assets, providing a comprehensive solution for content creators. This format allows you to store geometry, textures, animations, lighting, materials, and more in a single file. This comprehensive data storage capability simplifies asset management, ensuring that all the necessary components are packaged together and can be easily accessed or modified as needed.
One of the drawbacks of FBX is that it is a proprietary file format owned by Autodesk. This means that the specifications of the format are not publicly available, making it more challenging for third-party developers to create software that fully supports FBX. While Autodesk provides an SDK for FBX, the closed nature of the format can sometimes limit interoperability with certain software applications.
FBX files can sometimes be quite large, especially when they contain complex geometry, high-resolution textures, or numerous animations. This can pose challenges when it comes to file storage and transfer, particularly for projects with limited bandwidth or storage capacity. Files may require additional time and resources for processing, potentially impacting workflow efficiency.
While the complete specification is not publicly available, Autodesk provides an SDK Programmer's Guide that allows developers to work with FBX files and access the necessary information.
This file format itself does not require any specific sub-extensions, as the ".fbx" extension alone is sufficient to identify the file as an FBX file.
To open this file, you will need a compatible software application, for example, CAD Exchanger Lab. Launch the software and navigate to the 'New file' option. Browse your computer's directories and locate the .fbx file you want to open. Then select it and click "Open". Once the import process is complete, the .obj file should be loaded into the software, allowing you to view and interact with the 3D model and associated data.
FBX was initially developed by Kaydara, a Canadian software company, in the late 1990s. The purpose behind creating FBX was to provide a universal file format that could facilitate the exchange of 3D content.
In 2006, Autodesk, a leading software company, acquired Kaydara and took ownership of this format. Autodesk continued to develop and enhance this format, expanding its capabilities and compatibility with their various software applications such as Autodesk Maya and MotionBuilder. With Autodesk's support and resources, FBX gained even more traction and became widely adopted in the industry.
Throughout its evolution, FBX has expanded its capabilities to encompass an extensive array of features. These include geometry, textures, animations, cameras, lights, materials, and more. As a result, it has emerged as a widely accepted format for exchanging 3D assets, not just within Autodesk software, but also across diverse software applications from different vendors.
