QuickCurve is a modeling add-on that enables users to draw 3D geometry directly in the viewport using curves. The tool supports drawing with round profiles, box shapes, custom standard profiles, or completely custom objects.

It includes features for sketching directly on surfaces or along a specialized 2-point workplane. The add-on provides built-in tools for mirroring, arrays, and a curve eraser that can split paths. Users can also utilize wrap modes to draw curves that hug the surface of existing 3D models and instantly convert their drawn curves into finalized geometry.
