# Your STEP model. Directly in the browser.

Quelle: <https://mvg-frankfurt.de/en/step-viewer>

> View, rotate and zoom STEP and STP files free of charge in the browser. The preview processes your file locally – regardless of manufacturability.

View CAD · understand the shape

Open, rotate and view from all sides. You do not need to choose a material for this. You can also view geometries that we cannot manufacture as a 3D model.

STEP / STP · up to 20 MB · processed locally in your browser. For the preview alone, your CAD file is not transferred to our server.

## A preview, not yet a production release.

The viewer shows readable STEP geometry. Whether we can make a laser-cut or bent part from it is checked separately in the calculation. Damaged files or very complex models can exceed the limits of the browser preview.
