CurviBlend is a surface patching toolkit that generates quad-based surfaces to connect multiple curves or meshes. It uses a non-destructive, group-based workflow to analyze selected geometry and automatically generate closed loops of connecting Bezier curves.

The tool offers two primary algorithms for surface generation: a fast Bilinear mode for G0 continuous patches and a high-quality Bicubic mode for tangent-smooth G1 continuous patches. Users can choose to create patches from organized groups or generate them on the fly from any selection of two or more curves.

Surface generation is controlled through an interactive modal workflow, allowing users to adjust parameters like U/V segment resolution, input adherence, and boundary snapping while seeing real-time updates in the 3D viewport. Additional edge control features include curve rectification and the ability to project surface boundaries onto a smoothed, interpolated guide curve.
