Turn a BREP CAD model into an STL mesh. Curved surfaces are meshed finely enough to stay smooth, and the part keeps its real size and orientation.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
STL is already selected. You can switch to any other output from the menu.
Click Convert and your STL 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.
STL describes a surface as a list of triangles, with no colour, material or unit information. It is the default file for 3D printing and is exported by almost every CAD and modelling program.
BREP stores exact surfaces; STL needs triangles. We mesh each surface with a deviation of 0.05% of the part's size, which keeps holes and fillets smooth for printing and rendering.
Dimensions stay in the units of the original file, usually millimetres.
No. Curved faces are meshed with a tight tolerance, so holes and fillets stay smooth.
Yes. The mesh has the same dimensions as the CAD model.
No. Everything runs in your browser.
