SOLIDWORKS is a proprietary format, used by the SOLIDWORKS software, a professional 3D CAD software application. It utilizes the file extensions ".sldprt" for part files and ".sldasm" for assembly files. In this format, all the necessary geometric information, features, dimensions, constraints, and other design data are stored to represent and document a 3D model.
CAD Exchanger can read files from version 2004 to version 2023. Such support includes:

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.
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 file you want to open. Then select it 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.
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.
The JT format is a widely used lightweight 3D data format designed for efficient visualization, collaboration, and sharing of complex 3D models and assemblies. JT files retain the fidelity of the original 3D models while minimizing file size, enabling fast loading and efficient data transmission. The format supports features like precise geometry, polygonal meshes, product structure, PMI, and animations.
CAD Exchanger can import files compliant with the JT formats from 8.0 to 10.5 and ISO14306:2012 and export files compliant with the JT formats 9.5 and ISO14306:2012. Such support includes:

Advanced compression and economical data representations
This file format employs advanced compression techniques to reduce file sizes without compromising the quality of the content. This enables efficient transmission and storage of 3D models and other visual data.
In addition to compression, JT excels in economical data representations. The format is structured in such a way that it is relatively easy to read in a selective manner. Files typically have smaller file sizes than STEP files with comparable geometry. This is achieved by efficiently representing mesh data through topological compression algorithms, which take advantage of the connectedness between mesh patches. Despite the economical representation, JT files maintain their integrity and provide a comprehensive visualization of the original content.
The format is designed to handle complex 3D mesh data efficiently, making it ideal for applications that require high-quality mesh representation. JT allows for the precise encoding of mesh data, including vertex positions, normals, texture coordinates, and more. It supports both triangular and polygonal meshes, enabling the representation of intricate geometric shapes with smooth surfaces.
Moreover, JT provides robust support for mesh attributes and properties. This means that additional information, such as material properties, colors, and transparency, can be associated with individual mesh elements or the entire mesh.
While the ISO standardization brought greater openness and interoperability to this format, the legacy of its proprietary history can still be observed in certain cases. It's worth noting that the specifications for JT 7.x and earlier versions were not publicly accessible, and the format was essentially proprietary, so there were difficulties in reading and writing this format in other CAD software. Fortunately, these versions of files are not used much these days.
Implementing full-fledged JT support can be a demanding task. It requires a deep understanding of the intricacies of the format's specifications and algorithms. This can be a barrier for smaller software developers or independent implementers who may not have the resources or expertise to fully grasp and implement the complexities of the format. As a result, the quality of JT support can vary significantly.
Another consequence of the proprietary nature of the JT format is its lack of openness. The latest JT precise geometry representation is based upon the Siemens PARASOLID, which means a high-quality implementation of the format must also be able to read and write this format.
Yes, it is. The JT Open Program, an industry consortium dedicated to promoting the widespread use of JT as a 3D data format, provides the JT file format specification to the public. It offers various resources, including technical documentation, whitepapers, and specifications related to the JT format. These resources can be accessed on the official JT Open Program website.
The JT format typically uses the file extension ".jt" to denote JT files. It is worth noting that alternative file extensions may also be used in certain cases, depending on the software or system. However, ".jt" remains the most commonly used and recognized extension for JT files across different platforms and applications.
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 .jt 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.
The JT format, also known as Jupiter Tessellation, has a long history that traces its origins back to the 1990s. It was developed by Engineering Animation Inc., a company specializing in computer graphics and visualization software. EAI created the JT format as a lightweight and versatile solution for visualizing and sharing 3D data in industries such as manufacturing and engineering.
In 2001, EAI was acquired by UGS Corporation, which later became Siemens Digital Industries Software. Siemens recognized the potential of the JT format and continued its development, expanding its capabilities and promoting its adoption in various industries. Over the years, Siemens has worked to enhance the format, improve its compression techniques, and ensure compatibility with a wide range of software applications.
The JT format gained further recognition and acceptance when it was standardized by the International Organization for Standardization in 2012 as ISO 14306. This ISO standardization solidified the JT format's position as a reliable and widely supported file format for 3D visualization and data exchange. Today, the JT format continues to evolve and is utilized by numerous companies and industries worldwide for effective collaboration, efficient data sharing, and immersive 3D visualization.
