Quick Fillet is a modeling tool that generates curved, quad-based surfaces by interpolating selected cross-section edges. It utilizes edge selections spanning three different orientations to calculate and fill the rounded geometry.

The operator requires an even number of edges selected across three distinct directional sets, with each set containing an equal number of edges. It automatically determines the separation between edge sets based on the sharpest angles in the selection. Users can manually adjust the separation offset through the operator panel if the automatic calculation requires correction. The tool is accessed directly from the Edit Mode context menu.
