Autodesk 123DX, which was initially released in 2009 whose native file format was 123DX, was an easy to use Computer Aided Design (CAD) application aimed at home/hobbyist users for creating 3D models.
The 123DX application was retired in 2016 with users moving on to the more advanced Fusion 360 application from Autodesk.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.
There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.
First click the "Upload..." button, select your 123DX file to upload. Your 123DX file will be uploaded to our servers. When the 123DX to STL conversion has completed, you can download your STL file straight away.
We aim to process all 123DX to STL conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development with new features being added every week.
