Do I need AutoCAD or design software to use FileCrank?

No. FileCrank is designed for users without SolidWorks, Fusion 360, or any other CAD software. Upload your file, choose your options, and download the result — all in your browser.

Can I control the mesh quality and level of detail?

Yes. FileCrank supports three mesh-quality presets: Low (small file, fast processing), Medium (default, balanced), and High (finest detail, larger file). Choose based on your 3D printer's capabilities and the detail level you need.

What if my STEP file has multiple parts or an assembly?

FileCrank handles STEP assemblies correctly. All parts are merged into a single closed STL suitable for 3D printing. If you need to print individual parts, convert the STEP to STL and then split the mesh in your slicer software or use an STL editing tool.

How does FileCrank's conversion quality compare to desktop software like SolidWorks?

FileCrank's STEP to STL conversion creates valid, printable STL files that are identical in quality to desktop CAD software exports. The mesh is closed and ready for slicing immediately. For most 3D-printing workflows, the quality is indistinguishable from SolidWorks.
