What is a STEP file?
STEP (Standard for the Exchange of Product model data) is a widely adopted ISO standard (ISO 10303) for exchanging 3D CAD data between different software systems. It stores precise geometric and product structure information.
STEP files are ideal for sharing designs in engineering, manufacturing, and prototyping. They are compatible with most major CAD programs and ensure consistent model quality across platforms.
How to open STEP files
STEP files are supported by almost every CAD program, including SolidWorks, CATIA, Fusion 360, FreeCAD, and more. They are ideal for interoperability between platforms.
Use AnyConv to convert STEP files into STL, IGES, or other formats needed for 3D printing or further design.
