Convert BREP to STEP without losing precision. The exact surfaces and solids are passed straight across, so nothing is turned into triangles.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
STEP is already selected. You can switch to any other output from the menu.
Click Convert and your STEP file is ready in seconds. Download it straight away.
BREP is the native exact-geometry format of the OpenCascade kernel, used by FreeCAD, CadQuery and many engineering tools built on it.
STEP stores exact CAD geometry: true planes, cylinders, cones and freeform surfaces joined into solids. It is the standard way to move parts between CAD systems such as SolidWorks, Fusion 360, Inventor, CATIA and FreeCAD.
Both BREP and STEP store exact CAD geometry, so this is a direct translation using the OpenCascade CAD kernel. We check the converted part has the same volume as the original.
No. The exact geometry is translated directly; it is never turned into a mesh.
Geometry is kept exactly. Colours and assembly names may not carry over between CAD formats.
No. Conversion runs in your browser and your file stays on your computer.
