About STEP Format

STEP (Standard for the Exchange of Product Data) is an ISO standard (ISO 10303) for representing 3D objects. It's the most widely used neutral file format for sharing CAD models between different software systems while preserving geometry, topology, and product manufacturing information.

Why Convert to STEP?

  • Universal Compatibility: Works with virtually all professional CAD software
  • Data Integrity: Preserves complex geometry, assemblies, and metadata
  • Industry Standard: Widely accepted in aerospace, automotive, and manufacturing
  • Long-term Archival: ISO standard ensures future accessibility

Supported CAD Software

  • • SolidWorks (.sldprt, .sldasm)
  • • CATIA (.catpart, .catproduct)
  • • Autodesk Inventor (.ipt, .iam)
  • • PTC Creo (.prt, .asm)
  • • Siemens NX (.prt)
  • • Fusion 360
  • • Rhino 3D (.3dm)
  • • And many more...

Frequently Asked Questions

What is the difference between STEP and IGES?

STEP is a newer, more comprehensive standard that supports solid models, assemblies, and product data. IGES is older and primarily handles surface geometry. STEP is generally preferred for modern CAD data exchange.

Will my assembly structure be preserved?

Yes, STEP AP214 and AP203 formats preserve assembly structures, including part relationships and constraints, making it ideal for complex multi-part models.

Is the conversion process secure?

All conversions are processed locally in your browser for maximum security. Your CAD files never leave your computer, ensuring complete confidentiality of your designs.
