## subtree: design

node name | type | flags | description
via_thickness | rnd_cfn_coord | 0 | [OBSOLETE] used to be via gemoetry for the via tool; replaced by via padstack prototype
via_drilling_hole | rnd_cfn_coord | 0 | [OBSOLETE] used to be via gemoetry for the via tool; replaced by via padstack prototype
line_thickness | rnd_cfn_coord | 0 | <line_thickness>
clearance | rnd_cfn_coord | 0 | <clearance>
via_proto | rnd_cfn_integer | 0 | prototype used for vias
text_scale | rnd_cfn_integer | 0 | text scaling in %
text_thickness | rnd_cfn_coord | 0 | override stroke font text thickness
text_font_id | rnd_cfn_integer | 0 | <text_font_id>
bloat | rnd_cfn_coord | 0 | core: size of box-style clearance around text objects; old plugins: gap between copper features on different nets
shrink | rnd_cfn_coord | 0 | [OBSOLETE] minimum overlap between connected copper features
min_wid | rnd_cfn_coord | 0 | core: minimum copper thickness in stroked text, core+plugins: implicit outline rectangle thickness
min_slk | rnd_cfn_coord | 0 | core: minimum silk thickness in stroked text, core+plugins: implicit outline rectangle thickness on silk layers
min_drill | rnd_cfn_coord | 0 | [OBSOLETE] minimum drill diameter
min_ring | rnd_cfn_coord | 0 | [OBSOLETE] minimum annular ring
poly_isle_area | rnd_cfn_real | 0 | polygon island mininum area used to throw out islands too small in MorphPolygon; specified in nm^2; note: due to historical bugs, half or double of the value may be used by the code.
fab_author | rnd_cfn_string | 0 | Full name of author for FAB drawings
initial_layer_stack | rnd_cfn_string | 0 | deprecated.
paste_adjust | rnd_cfn_coord | 0 | Adjust paste thickness
hierarchy_sep | rnd_cfn_string | 0 | separator character in hierarchic design levels (only the first character is used); e.g. if it is /, S1/S2/R4-5 is interpreted as S1/S2/R4 as the refdes (5 is terminal id), and that R4 is under S2 which is under S1 in the hierarchy
