Open STEP files (also .stp) — free, in your browser
STEP (.step or .stp) is the standard for exchanging CAD models in mechanical engineering and industry (ISO 10303). SolidWorks, Inventor, Fusion 360, CATIA and Creo read and write it; it stores the true shapes, not just triangles.
With the free downloadlink viewer you open a .step / .stp file directly in your browser. Nothing is installed, and without an account nothing is uploaded either — when you are logged in, the viewer keeps your file in My files.

What the viewer does with STEP files
You rotate, zoom and pan the model, hide parts, measure distances with snapping to corners and edges, and make a section.
Good to know
The viewer shows the shape, not the design history or the parameters from the CAD program.
