Frequently asked questions
Can I view STEP files without installing CAD software?
Yes. Drop a .step or .stp file and an OpenCascade kernel compiled to WebAssembly reads it locally in your browser and shows the solid in 3D — no install, no upload.
Are IGES and DXF files supported too?
IGES works exactly like STEP. DXF drawings open as a 2D line view you can pan and zoom, since DXF is a drawing format rather than a 3D model.
Is my CAD data private?
Completely. The CAD kernel runs on your own device. Proprietary designs are never sent to a server — the page even works offline once loaded.
Can I convert STEP to STL or GLB?
Yes. The CAD converter turns STEP and IGES files into STL, GLB, OBJ or PLY, ready for 3D printing or game engines.
