Browser-based STL / 3MF / OBJ to OBJ / STEP converter
Designed for CAD models made primarily from planes, straight edges, primitives, and extrusions.
Models with many free-form surfaces, such as figurines, usually produce impractically large files.
For 3MF and OBJ files, textures, materials, and colors are discarded; only geometry is converted.
⚠ Large or high-polygon models may take time to load, detect round-hole candidates, convert to STEP, and prepare the download. Keep this page open while processing.

☑ Your data is processed locally and is never uploaded. Recommended round holes are selected automatically and can be deselected individually. Round-hole detection uses coplanar-face merging.
When importing into Plasticity, enabling “Stitch unjoined sheets” can make solid creation more reliable.
