Settings reference

This reference explains the settings used by the stable tools. Controls appear only where they apply to the current mode, shape or layout. Displayed measurements follow your selected mm/mil preference; the examples below use millimetres.

Content and symbols

Control	Effect and useful check
Make	Chooses Label, Label + symbol or Symbol only
Label text / Labels (one per line)	The text content; header/array lines correspond to repeated positions
Quick label	Starts from reusable text and optional symbol content
Text layout	Single text or Title + subtitle
Subtitle	Supporting text beneath the main title
Symbol	Selected library asset and variant
Symbol position	Left or right of text in the stable combined label tool
Symbol size	Physical icon height; 0 means automatic relative to text height
Symbol gap	Separation from the lettering, distinct from container padding

A symbol is hidden when the selected content mode does not use it. Switching to Symbol only can remove text-related controls from view without deleting the library asset.

Container geometry

Control	Effect and useful check
Shape	Overall enclosure form; available dependent controls can change
Appearance	Filled/inverted, outline or other available rendering treatment
Corner radius	Roundness of compatible corners
Outline width	Border thickness in outline-style artwork
Feature size	Size of shape-specific features such as notches or points; it is not a universal fabrication limit
Direction	Orientation of directional enclosure details
End treatment	Matched ends or independent edge treatments
Left/right edge	Individual end styles for ordinary labels
Independent long edges	Pin-side and label-side corner treatment on header enclosures
Top/bottom/left/right padding	Space between the content and its container

A shape can be constrained by its content and minimum geometry. Inspect the actual preview after changing a radius, border or asymmetric end rather than treating a field as an isolated visual promise.

Typography

Control	Meaning
Typeface	Font used for the generated lettering
Alignment / minimum width	Align text within the available region; minimum width sets a lower bound rather than scaling letters
Main text height	Physical lettering size; the container is larger once padding is included
Line spacing	Spacing between lines of main text
Subtitle height / gap	Supporting-line size and separation from the main title
Subtitle typeface	Follows the main face by default; an override is available in advanced controls
Underline main text	Generates an underline as real board geometry
Underline thickness / gap	Stroke width and distance below the lettering

Text appearance depends on glyph proportions and stroke weight as well as height. Check special characters and counters at the smallest planned output size.

The stable Standard tool also exposes Legacy inline markup, with Overline style (Square/Rounded) and Overline weight. When enabled, inherited ~{...} markup can overline a text group; use a small test such as ~{RESET} and inspect its output. These legacy controls differ from the newer development formatting and independent overline controls.

Header overlays

Control group	Meaning
Pin count and label lines	Number of positions and text assigned to them
Orientation	Horizontal or vertical arrangement
Pins on / Pin 1 end	Relationship between the text, pin row and first position
Pin 1 marker	Optional additional orientation cue
Connector spacing	Hardware region, text offset and outer padding
Opening style	None, continuous plug opening or individual pin openings
Opening width / end padding	Physical removed area around connector/pins
Leading/trailing padding	Extension at the first and last positions

Stable pitch is 2.54 mm. Text height must fit the pitch. For details and order checks, use Header overlays.

Component tools

Control group	Meaning
Preset	A starting body envelope for a common component
Width / height	Physical body envelope dimensions
Clearance	Space added around the envelope
Cutout shape / radius	Geometry reserved for the component region
Label position / text gap	Side and separation of text from the component
Array count	Number of repeated callouts
Array orientation	Row or column arrangement
Array pitch	Centre-to-centre component spacing

Choosing a preset does not validate it against your exact part. See callouts and arrays.

Machine codes

Control	Meaning
Payload	Actual encoded data
Module size	Width of one QR square or the base narrow barcode element
Presentation	Plain QR, rounded frame, or frame with footer
Extra frame gap	Decoration spacing in addition to the protected QR quiet zone
Footer text / height	Short instruction in the QR frame; does not alter payload
Bar height	Physical height of Code 128 bars
Show text below code	Enables independent human-readable artwork
Readable text / height / gap	Caption content, size and spacing beneath the code

The QR default module size is 0.35 mm. Code 128 defaults are 0.25 mm modules and 4.0 mm bars, with guarded minimums of 0.20 mm and 3.0 mm. Always check scan and fabrication requirements.

Layers and preview

Place artwork on selects the generated layer set. Preview layer selects the viewed target within that set. Fit, + and − change view framing, not physical output dimensions. At least one target layer is required. Read layers and fabrication before choosing copper or mask.

Application Settings map

Settings page	Use
General	Appearance and measurement display
Profiles and defaults	Per-module default profile, clear default and profile deletion
Uploads → Symbols	Personal/project SVG assets and symbol variants
Uploads → Quick Labels	Create, edit and remove custom reusable label content
Data & backup → Backup & reset	Export/restore personal setup or reset custom data
Data & backup → Bundled visibility	Hide/show shipped symbols and quick labels
About & help	Version and support destinations

Read profiles and backups before restoring or resetting data. The development build adds Settings pages and controls that are documented separately.
