The SOLIDWORKS format contains comprehensive design information. It includes not only the 3D geometry of the part or assembly but also feature history, dimensions, constraints, materials, and other design parameters. This level of detail allows for easy modification, analysis, and collaboration within the SOLIDWORKS ecosystem.
SOLIDWORKS is a widely adopted CAD software, and its proprietary format is supported by various CAD tools, engineering applications, and manufacturing processes. This compatibility ensures seamless data exchange and collaboration between different stakeholders, such as designers, engineers, and manufacturers. Using the SOLIDWORKS format facilitates effective communication and streamlines the workflow throughout the product development lifecycle.
The SOLIDWORKS format is proprietary, meaning it is owned and controlled by Dassault Systèmes, the company behind SolidWorks. As we wrote above, this format is widely used in engineering and manufacturing, but there are still softwares and tools that do not support SOLIDWORKS, due to its proprietary nature. While SolidWorks does provide options to export to various standard formats like STEP or IGES, the main challenge is that neutral formats do not contain all the design information, but only the final result of the design process. Also, there may be challenges in maintaining full fidelity and compatibility when working with other CAD systems.
Managing a large number of files when working with complex models can become challenging, especially when it comes to transferring data. Some files can be lost or deliberately hidden. Without all the files together, the user only has an approximate model geometry in the form of a polygonal mesh, but all design information, including the exact geometry, is missing.
The file extension ".sldprt" is used for SOLIDWORKS part files. They are the building blocks of assemblies and are created and modified within the SOLIDWORKS environment.
For assembly files, SOLIDWORKS uses the ".sldasm" extension. Assembly files represent the coming together of multiple parts into a larger, functional unit. They are essential for visualizing and analyzing the interaction between different components.
Drawing files in SOLIDWORKS have the ".slddrw" extension. These files contain 2D representations of parts or assemblies. They enable the generation of design documentation suitable for further usage in product lifecycle, in particular they serve as blueprints for creating physical parts.
SOLIDWORKS also utilizes template files for creating new documents. Template files have the extensions ".prtdot" for part templates and ".asmdot" for assembly templates. These files define the default settings, styles, formats, and other parameters for creating a new part or assembly documents.
Additionally, SOLIDWORKS features a library feature functionality that allows users to create reusable design elements. Feature files for library features use the ".sldlfp" extension. These files define specific features that can be applied to parts or assemblies, saving time and effort by enabling the reuse of complex or commonly used design elements.

The SOLIDWORKS format history dates back to the early 1990s when SolidWorks brand was founded by Jon Hirschtick. The goal was to create a user-friendly, parametric 3D modeling software that would revolutionize the CAD industry.
In 1995, the first version of SOLIDWORKS was released, introducing a groundbreaking approach to 3D modeling. As SOLIDWORKS gained popularity, it expanded its capabilities and introduced new features with each subsequent release. The software focused on improving design efficiency, accuracy, and collaboration.
In 1997, Dassault Systèmes, a renowned software company, acquired SolidWorks Corporation, bringing SOLIDWORKS into its product portfolio. The SOLIDWORKS format has become a standard in the CAD industry.
Today, SOLIDWORKS remains one of the most widely used CAD software packages, serving millions of users worldwide. Its continuous development, integration with other technologies, and commitment to user-friendly design have solidified its position as a leading CAD solution in the industry.

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.
