dwg files independently, a standard process is creating the 3D component model and converting the part to a drawing using the software. Drawing files (.dwg) are the digital format of a 2D component drawing.

However, while some file types may work in different environments, the accuracy in translating one file type to another software is not guaranteed. As a result, they are most accurate when used in their intended software. Native CAD files often contain more information than their neutral counterparts. As a result, the absolute dimensions and features of STEP and IGES files may not translate precisely as the native file specified.
STEP is a newer format and is popular due to its improved accuracy over IGES.Īlthough these file types can work with most software, the conversion from native to neutral can introduce errors in the file. p21) are neutral file types used for solid 3D models.
iges) convey surface models and can include gaps, misaligned orientations, or missing surfaces. There are two principal neutral CAD file types: IGES and STEP. Neutral file typesĮngineering teams can use these file types to communicate components in a customer assembly or convey design features to a contract manufacturer who would fabricate the part. The list of file types is not comprehensive, but it reflects common file types used in modern engineering design and manufacturing. Designers can use neutral file formats in any software, while native files contain information software designers optimized for their platform. native CAD formatsĬAD files exist in two primary formats: neutral and native.

3D files, and what happens when you export CAD to a PDF or TIFF file. In this article, we explain the pros and cons of native vs. This type of situation creates the need for a neutral file type, which can be opened by either system. For example, you might want to share CAD with a supplier, but your company uses one CAD system (say, Creo) and your supplier uses another (like SolidWorks). Sharing CAD is not always straightforward.
With the rise of remote work and international project teams, engineers must identify the best way to share CAD and collaborate virtually. They are the medium over which engineering teams collaborate to bring innovation and improvement to an industry. AutoCAD file extensions are .dwg (3D & 2D) & .dwf (3D & 2D)ĬAD Interop distributes several softwares to view, translate and validate AutoCAD files.Whatever the application, CAD files are essential to product design and development. AutoCAD supported native or neutral formats are IGES, DXF, DWG, ACIS. In summary, AutoCAD is a CAD software developed by Autodesk. AutoCAD Architecture, on the other hand, is a CAD software for architects and construction professionals, which allows them to create construction plans with specific functionalities such as the design of walls, doors and windows. For example, AutoCAD Mechanical is a mechanical CAD software based on AutoCAD, which allows users to create drawings of mechanical parts with specific features such as the design of gears, springs, screws and other mechanical elements. Recording and playback in ACIS format from or to an Autodesk product is achieved without conversion and therefore without interoperability problems at the geometry level.Īdditionally, Autodesk has also developed additional software solutions to improve interoperability with AutoCAD. For example, AutoCAD is compatible with industry standards such as IGES (Initial Graphics Exchange Specification), STEP (Standard for the Exchange of Product Model Data), and STL (Standard Tessellation Language).ĪCIS is the geometric engine of all software developed by Autodesk. Regarding CAD interoperability capabilities, AutoCAD has a wide variety of features to facilitate collaboration between different CAD software. These formats allow users to share their drawings with people who do not have access to AutoCAD, while preserving the quality and accuracy of the drawings. However, AutoCAD also supports exporting to other CAD file formats, such as DXF (Drawing Exchange Format) and DWF (Design Web Format). This means that files created in AutoCAD can only be opened in software that supports this format, such as AutoCAD itself or other CAD software that supports importing. Developed by Autodesk, AutoCAD helps create 2D and 3D drawings with high precision and efficiency.ĪutoCAD files have a ".dwg" (for "drawing") file extension, which is an Autodesk proprietary format. AutoCAD is computer-aided drafting (CAD) software widely used in the design and engineering industry.
