# pcb-rnd conf tree

## subtree: editor

node name | type | flags | description
zoom | real | 0 | default zoom
buffer_number | integer | 0 | number of the current buffer
clear_line | boolean | 0 | new lines/arc clear polygons.
clear_polypoly | boolean | 0 | new polygons clear polygons.
full_poly | boolean | 0 | new polygons are full polygons.
unique_names | boolean | 0 | OBSOLETE: force unique names
snap_pin | boolean | 0 | snap to pins and pads
snap_offgrid_line | boolean | 0 | Snap to certain off-grid points along a line.
marker_snaps | boolean | 0 | marker snaps to grid or snap points, as any other click
highlight_on_point | boolean | 0 | Highlight if crosshair is on endpoints.
show_solder_side | boolean | 0 | mirror output
save_last_command | boolean | 0 | OBSOLETE: use the session-persistent command line history instead (press the up arrow)
line_refraction | integer | 0 | value for line lookahead setting
save_in_tmp | boolean | 0 | emergency save unsaved PCB data (despite the user clicks don't save) when: user starts a new PCB; user quits pcb-rnd. Does not affect the on-crash emergency save.
all_direction_lines | boolean | 0 | enable lines to all directions
rubber_band_mode | boolean | 0 | move, rotate use rubberband connections
rubber_band_keep_midlinedir | boolean | 0 | keep line direction when a middle line is moved
swap_start_direction | boolean | 0 | change starting direction after each click
show_drc | boolean | 0 | show drc region on crosshair
auto_drc | boolean | 0 | when set, PCB doesn't let you place copper that violates DRC.
conn_find_rat | boolean | 0 | connection find includes rats; when off, only existing galvanic connections are mapped
show_number | boolean | 0 | OBSOLETE: pinout shows number
orthogonal_moves | boolean | 0 | move items orthogonally.
reset_after_element | boolean | 0 | OBSOLETE: reset connections after each element while saving all connections
lock_names | boolean | 0 | lock down text so they can not be moved or selected
only_names | boolean | 0 | lock down everything else but text so only text objects can be moved or selected
thin_draw | boolean | 0 | if set, objects on the screen are drawn as outlines (lines are drawn as center-lines). This lets you see line endpoints hidden under pins, for example.
thin_draw_poly | boolean | 0 | if set, polygons on the screen are drawn as outlines.
as_drawn_poly | boolean | 0 | if set, also draw the as-drawn outline of polygons
wireframe_draw | boolean | 0 | if set, lines and arcs on the screen are drawn as outlines.
local_ref | boolean | 0 | use local reference for moves, by setting the mark at the beginning of each move.
check_planes | boolean | 0 | when set, only polygons and their clearances are drawn, to see if polygons have isolated regions.
hide_names | boolean | 0 | when set, subc floater text objects (typical use case: refdes text) are not drawn.
description | boolean | 0 | obsolete - DO NOT USE - kept for compatibility
name_on_pcb | boolean | 0 | obsolete - DO NOT USE - kept for compatibility
subc_id | string | 0 | subcircuit ID template for diplaying the subcircuit label on the subcircuit layer; default to displaying the refes, if empty; syntax if the same as for DYNTEXT
term_id | string | 0 | terminal ID template for diplaying the subcircuit label on the subcircuit layer; default to displaying termid[intconn], if empty; syntax if the same as for DYNTEXT
move_linepoint_uses_route | boolean | 0 | Moving a line point calculates a new line route. This allows 45/90 line modes when editing lines.
auto_via | boolean | 0 | when drawing traces and switching layers or when moving an object from one layer to another, try to keep connections by automatically inserting vias.
route_radius | real | 0 | temporary: route draw helper's arc radius at corners (factor of the trace thickness)
io_incomp_popup | boolean | 0 | wether to enable popping up the io incompatibility list dialog on save incompatibility errors
io_incomp_style | string | 0 | view listing style (list or simple), when io_incomp_popup is true
click_time | integer | 0 | default time for click expiration, in ms
enable_stroke | boolean | 0 | Enable libstroke gestures on middle mouse button when non-zero
live_routing | boolean | 0 | autorouter shows tracks in progress
beep_when_finished | boolean | 0 | flag if a signal should be produced when searching of connections is done
undo_warning_size | integer | 0 | warn the user when undo list exceeds this amount of kilobytes in memory
subc_conv_refdes | string | 0 | automatic refdes value assigned to new subcircuits on conversion from objects - if empty, no refdes text or attribute is added; if the value is <?>, the refdes text object is added but no refdes attribute is created
