Open STEP on Phone

STEP is an engineering CAD exchange format used for precise product and mechanical models.

• STEP needs CAD-grade geometry parsing.
• Useful geometry viewing often requires a full engineering model kernel.
• A structure summary is safer and lighter than rebuilding precise CAD geometry in a browser.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.

• model/step
• application/step
• application/octet-stream

• Choose the STEP file on the home page.
• OpenOnPhone reads header metadata, product names, and entity counts locally.
• Use a CAD tool when you need geometry, measurements, conversion, or editing.
