Export a STEP file from SOLIDWORKS

Steps

1. Open the top-level assemblyOpen the .SLDASM of the whole product, not a part file. Resolve lightweight components so every part is fully loaded.
2. File › Save AsIn the dialog, set Save as type to STEP AP214 (*.step;*.stp). AP242 is fine too.
3. Check the optionsThe default STEP options are fine: they write the assembly with its structure, part names and positions. Only change them if your company requires a specific AP version.
4. SaveChoose a name and save. SOLIDWORKS writes one .step that contains every component with its position.

Tips for a better manual

• Rename parts like “Part12” in the FeatureManager tree first: the names end up in the manual.
• Hide or suppress fasteners you do not want in the manual before exporting.

Next: make the manual

Drag the .step file into the workbench. It opens in your browser; nothing is uploaded.
