Questions & Answers
STEP files: Frequently Asked Questions
What are STEP files?
STEP (Standard for the Exchange of Product model data) is a file format used for 3D CAD (computer-aided design) data exchange. It is an ISO standard and is widely used in the manufacturing industry for exchanging information between different CAD software systems. STEP files can store information about geometry, topology, and attributes of 3D models. They can also include information about materials, textures, and other properties. The format is designed to be platform-independent and can be used on a variety of operating systems and software applications. STEP files are commonly used for sharing and collaboration between different engineering and design teams.
Can reaConverter open STEP files?
reaConverter fully supports the STEP file format – open, edit, and export STEP files to any other popular file format with ease.
Do I need 3D or CAD software to convert STEP files?
No. reaConverter reads STEP files on its own, so the conversion needs no SolidWorks, Fusion or other CAD seat. It runs offline on your PC and handles whole folders at once, which suits model libraries, supplier deliveries and product ranges that have to reach people working in other software.
How do I change STEP to another format?
reaConverter is a user-friendly tool for converting STEP files. Once installed on your computer, it allows you to convert all your .step files at once with just a few clicks. You can even convert STEP models directly from Windows Explorer using the right-click menu — fast and convenient.
Can I convert STEP online?
If you only want to convert a few STEP files, you are welcome to try our free online STEP converter.
How can I turn STEP files on my computer to another format?
The best way to convert STEP files on your PC is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch files conversions, including conversion from STEP.
