Open-Source Tool Converts STL Meshes to STEP Files with B-Rep Volumes
The tool, stl2step, can process STL meshes and export them as STEP files with B-Rep volumes, improving CAD and CAM workflows.
The open-source project stl2step converts STL meshes to STEP files with B-Rep volumes, enabling CAD and CAM programs to process them as true boundaries rather than loose collections of triangles.
The tool, developed by BlinkingSun and released under the MIT license, uses OpenCascade as its geometry kernel and supports Linux, macOS, and Windows.
The software offers two modes: Verbatim, which preserves the original triangles, and TrueForm, which attempts to mathematically describe the original form and recognizes planes, cylinders, and rounded edges.
