This add-on automates the topology routing needed to create clean supporting edges on 2D and 3D objects using a subdivision surface modifier. Rather than manually cutting lines with the knife tool and dissolving edges, users can select corner vertices or edges and apply the operation to immediately generate holding edges.

The tool is designed for convex surfaces and ensures the resulting sharpened corners maintain strict quad-based topology. It operates in Edit Mode from the Tool section of the 3D viewport. After applying the operation, a factor slider allows for fine-tuning the tightness of the sharpened corners.
