Now, how can you view a 3D model present in the .stp/ .step file on your Windows 10 PC? The native 3D apps like 3D Viewer or Paint 3D don’t let you open a STEP file.

3D Viewer is the default 3D file viewer app that you get in Windows 10. It lets you view 3D models of different formats such as STL, FBX, GLTF, OBJ, and other files.
