From cfb27d93c34c1739d5193d232be92da2148d7b18 Mon Sep 17 00:00:00 2001 From: Hakan Seven Date: Tue, 7 Apr 2026 10:58:46 +0300 Subject: [PATCH] feat: FILLET now supports Line-Arc, Arc-Line, and Arc-Arc pairs Extended FilletCommand and ChamferCommand to accept Lines and Arcs as first/second entity. Added fillet_line_arc() and fillet_arc_arc() geometry functions that find a tangent fillet circle between the two entities, trim each to the tangent point, and insert the fillet arc. r=0 case trims/extends to the nearest intersection without inserting an arc.
