Keep the input complete
For a part, preserve the source file and revision. For an assembly, include the required references and name the intended configuration. Missing components must not disappear from the task summary.

SLDPRT to STEP: SolidWorks Export Guide
SolidWorks to STEP is not available in this release. Read the format notes and ask your sender for a self-contained STEP file.
Not available in this release
This format or conversion is not supported. Ask the sender to export a self-contained STEP file, then inspect it with the STEP viewer.
Open STEP viewer →Before you use the result
Know what you are looking at.
Need a STEP file rather than the original SolidWorks document? Collect the correct configuration and any referenced components, then verify what the output retains.
Choose output settings deliberately
Agree the STEP profile with the recipient. Preserve bodies and components where they matter. Merging, flattening or simplifying the model should be an explicit choice, not an automatic way to make the task pass.
Include a result check
Reopen the output, verify units and scope, and inspect functional regions. Volume and outer dimensions are useful supporting checks, but equal totals cannot establish full geometric equivalence. Keep known limitations with the deliverable.
Questions about this task
Know the limits.
Which files can I process?
Supported inputs are STEP/STP, IGES/IGS, STL, OBJ, 3MF, static GLB/GLTF, bounded ZIP packages and DWG 2D previews. Capabilities depend on format. Native CAD formats and downloadable model conversion are unavailable.
Are files uploaded?
Yes. Selecting or dropping files uploads and processes them immediately in every tool. Files are processed temporarily on this server. The workspace displays the configured retention time. Delete in the file menu permanently removes your files; closing a view does not.
Do I need an account?
No. Your temporary workspace uses a browser session cookie. There is no account, subscription or permanent file library.
How are properties calculated?
STEP/IGES use B-Rep geometry; mesh files use approximate triangle properties and require closed consistent meshes for volume. DWG is a 2D preview without physical properties. STL/OBJ coordinates assume mm. Mass uses your chosen density.
