Open 123D File

File extensions are essential for defining a file's purpose, letting both the user and the operating system know the type of content within. One such file extension is 123D, which is associated with Autodesk 123D applications - a suite of impressive 3D design tools. However, there are multiple file formats and ways to open and use files with 123D extensions. In this article, we will discuss several methods and applications to help you access and work with 123D files.

Autodesk 123D Suite Applications

Autodesk 123D is a suite of powerful computer-aided design (CAD) applications, targeted towards hobbyists, students, and professionals looking to create 3D models. These applications include:

  • 123D Design for creating 3D models and prototypes
  • 123D Catch for transforming photos into realistic 3D models
  • 123D Make for turning 3D models into physical objects by cutting patterns
  • 123D Sculpt+ for intuitive sculpting of 3D models on touchscreen devices

Users can now generally create 123D files using these Autodesk applications and save them in different formats, such as .123dx, .stp, .obj, .dwg, and more. Therefore, varying according to the specific software used, the 123D file may require a different approach when attempting to open and use the file.

Opening and Editing .123DX Files

The primary file extension associated with Autodesk 123D Design is .123dx. This is the default file format that saves the 3D models, sketches, and part assemblies. To open and edit .123dx files, you will need access to 123D Design, which can be downloaded from the official 123D Design website.

Alternatively, you can use Autodesk Fusion 360, a cloud-based 3D modeling software that has gradually taken over 123D Design since its discontinuation in 2016. Fusion 360 supports importing .123dx files directly, allowing you to edit, design, or export to other CAD formats seamlessly. To access Autodesk Fusion 360, visit their official webpage.

Opening 123D .STP, .OBJ, and .DWG Files

Other commonly used file formats within the Autodesk 123D suite include .stp, .obj, and .dwg. The 123D applications typically offer the option to export your design in these formats to enable compatibility with other CAD software.

To open .stp and .obj files, you can use Autodesk Fusion 360 or other popular CAD software like FreeCAD, Blender, or Solid Edge. For .dwg files, Autodesk provides dedicated DWG viewing and editing software called DWG TrueView and AutoCAD respectively.

123D File Conversion

In some cases, you may need to convert your 123D files to different formats to ensure compatibility with other professional CAD software, like SolidWorks or NX. To do this, you can use the built-in file export feature in Autodesk 123D applications, or rely on third-party conversion tools like AnyConv or ConvertCADFiles.

123D File Important Information

Keep in mind that, while there are multiple ways to open and use 123D files, Autodesk 123D applications have been discontinued since March 31, 2017. Autodesk now mainly uses Fusion 360 as its primary cloud-based design application. However, you may still find previous 123D applications using their archived links.

Working with 123D files may require a variety of software depending on the specific format of the file. Make sure to check the file extension and use the appropriate software for each case. Finally, remember to always backup your CAD files in multiple formats to ensure compatibility across different design platforms and future-proof your work.
