Various workflows are now able to come from a single source of truth.įor design, this is interoperability between different design systems (CAD to CAD or CAD to CAE).įor manufacturing, this is the transmission of product definition into manufacturing/measurement software (CAD to CAM or CAD to CMM). STEP AP 242 also includes PMI ( product manufacturing information) such as GD&T, BOM, and other meta-notes & notes for building and measuring the part or assembly. More importantly, as companies move towards model-based definition and away from traditional paper-based workflows, STEP, specifically AP 242, has been the most popular file format for CAD interoperability downstream with departments, suppliers, subcontractors, and customers. Native CAD file formats from CAD software like CATIA and SolidWorks are proprietary and cannot directly be translated nor converted to another proprietary CAD system.īy exporting into a neutral CAD format like STEP, it allows for interoperability downstream. In this article we address AP 203, AP 214, and AP 242 pertaining to mechanical CAD design, 3D dimensional geometry, and product information. It is detailed into numerous Application Protocols (APs).

STEP is an ISO-standard ( ISO 10303-242:2020) written using the EXPRESS modeling language. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.STEP (Standard for the Exchange of Product Data) is a popular neutral 3D CAD file format that is interoperable among various CAD programs such as CATIA, Creo, SolidWorks, NX, Inventor, and others. Although you can use an Ad Blocker, if you like our STEP conversion tool please consider white-listing our site. What if I am using an Ad Blocker, will that affect things? No specialist software is needed to run any of our conversion tools.

Yes! Our STEP to STL tool will run on any system with a modern web browser. Can I convert STEP to STL on Windows, Linux, Android, iOS or Mac OS?

The resulting STL file, once created is deleted 1 hour after upload and the download link will expire after this time. Yes, of course! We do not store the STEP file you submit to us. Is it safe to convert my STEP to STL on ? Our tools are under constant development with new features and improvements being added every week. We aim to create the most accurate conversions with our tools. How accurate is the STEP to STL conversion? We aim to process all STEP to STL conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How long does it take to convert my STEP to STL? When the STEP to STL conversion has completed, you can download your STL file straight away. First click the 'Upload.' button, select your STEP file to upload.
