How to open a STEP file online

STEP (.step, .stp) is the format CAD systems use to exchange models. You do not need SolidWorks or any other CAD to look at one: Beenokle Model opens STEP right in your browser, free and without signing up.

Free, no sign-up. The file is not uploaded anywhere: the model opens on your own computer.

How to open it

  1. Open model.beenokle.ru — nothing to install. On Windows you can install the app instead.
  2. Drag the .step or .stp file into the Model window, or pick it on your computer.
  3. The assembly opens with its tree, part names and colours from CAD.

What you can do next

  • Find your way around the assembly: the tree follows the CAD structure, and a part can be found by name, hidden or isolated.
  • Measure exactly: radius, diameter, length, area and volume of faces and edges come from the exact geometry in the file, not from a triangle mesh.
  • Look inside with a section along an axis, a box or any plane.
  • Explode the assembly, build a parts list and lay out a drawing to ISO or GOST.

Good to know

  • Model works with finished geometry: you cannot edit a part and save the STEP back. It is not a CAD editor.
  • The file is read on your computer, so a large assembly takes a moment to open.
