Tools at critical risk
-
delete_componentDestructiveRemove a component from the PCB by its reference designator.
-
delete_schematic_componentDestructiveRemove a placed symbol from a KiCAD schematic (.kicad_sch). This removes the symbol instance (the placed component) from the schematic. It does NOT remove the symbol definition...
-
delete_schematic_net_labelDestructiveRemove a net label from the schematic.
-
delete_schematic_wireDestructiveRemove a wire from the schematic by start and end coordinates.
-
delete_symbolDestructiveRemove a symbol from a .kicad_sym library file.
-
delete_traceDestructiveDelete traces from the PCB. Can delete by UUID, position, or bulk-delete all traces on a net.
-
remove_schematic_component_propertyDestructiveRemove a single custom property from a placed schematic symbol. Built-in fields (Reference, Value, Footprint, Datasheet) cannot be removed — KiCad requires them on every symbol...
