A common question our community asks us is: can you import STEP files into Fusion 360? The answer is, yes you can! Are you hoping to import a STEP file into Fusion 360? We’ve got you covered with this quick tutorial.

What is a STEP File?

The STEP file format is a standard 3D model format that makes it easy to transfer 3D models between different users and different computer-aided design (CAD) and computer-aided manufacturing (CAM) programs.

The majority of STEP files are saved with the .stp file extension, however, some files may be saved with the.STEP extension. In either case, the files contain plain text data that a CAD or CAM tool uses to load a 3D model.

How to Import a .stp file into Fusion 360

Do you have a .stp file you need to import into Fusion 360? The easiest way to get a .stp file into a Fusion 360 document is to use the Upload command in the Data Panel.

Once you’ve selected Upload, choose the .stp file you want to use and select Open. Next, you’ll see your selected file on the Upload dialog, so you can now select Upload. After you select Upload, the file converts from a .stp file to a Fusion 360 file. The end result is a Fusion 360 file with the same name as the .stp file you uploaded.

After your file finishes uploading, you can insert it into an assembly by simply clicking and dragging the part into the assembly. You now have a normal Fusion 360 file with the ability to move and join the part to other parts in your assembly.
