From b9bd401b1185eabd4e835a84d9071e09ad7b645c Mon Sep 17 00:00:00 2001 From: KiCAD MCP Bot Date: Mon, 19 Jan 2026 19:24:59 -0500 Subject: [PATCH] feat: Add routing replication commands for Issue #30 Phase 2 Implements advanced trace manipulation and routing pattern copying: - Enhanced delete_trace with net-based bulk deletion and layer filtering - Added modify_trace to change width, layer, or net by UUID/position - Added copy_routing_pattern to replicate routing between component groups Co-Authored-By: Claude Opus 4.5 --- python/commands/routing.py | 305 ++++++++++++++++++++++++++++++++- python/kicad_interface.py | 2 + python/schemas/tool_schemas.py | 98 ++++++++++- 3 files changed, 398 insertions(+), 7 deletions(-) diff --git a/python/commands/routing.py b/python/commands/routing.py index 19de30f..c3a6c54 100644 --- a/python/commands/routing.py +++ b/python/commands/routing.py @@ -267,12 +267,44 @@ class RoutingCommands: trace_uuid = params.get("traceUuid") position = params.get("position") + net_name = params.get("net") + layer = params.get("layer") + include_vias = params.get("includeVias", False) - if not trace_uuid and not position: + if not trace_uuid and not position and not net_name: return { "success": False, "message": "Missing parameters", - "errorDetails": "Either traceUuid or position must be provided" + "errorDetails": "One of traceUuid, position, or net must be provided" + } + + #
