Open Main Menu → Preferences. Preferences apply to your account across every harness.

Appearance

Color scheme

The software supports both light and dark color schemes.

Light - Use the light color scheme
Dark - Use the dark color scheme
Auto - Match the color scheme to your system setting

Wires

Show wire stripes as dashed lines toggles how striped wires are drawn. When on, stripes are shown as dashes along the wire for easier reading at a glance. When off, stripes run parallel along the wire’s length for a more realistic appearance.

Outline black and white wires draws a gray border around white wires in light mode and around black wires in dark mode, so they stand out against the canvas. It is on by default and applies to wires, cable cores and twisted wires in both the schematic and layout views.

Part bars

Choose what the part bars under components show. The same choices apply to the part labels in the PDF export.

Standard details are the Part number, Manufacturer and Configuration. When a part has an internal part number, it can be shown in place of the manufacturer’s part number. Configuration shows the name of the configuration in use next to the part number, for any part type that has configurations (connector, terminal, splice, diode and resistor parts).

Each part type can then add its own details, or hide the standard details and show only its own:

Terminal parts - The terminal size.
Wire parts - The gauge. By default wire part bars show only the gauge.
Resistor parts - The resistance and power rating.
Diode parts - The voltage and current rating.
Covering parts - The length of a fixed-length covering. By default covering part bars show only the part preview.

Wiring tables

Choose which columns a wiring table shows when it is first added to the canvas. The Cavity and Terminal columns are always shown, and columns a component type doesn’t offer (such as Signal and Contact on anything but a connector) are left out of its tables.

Existing wiring tables keep the columns they have. right-click a wiring table to change its columns or to reset them to these defaults.

Show signals after destinations adds the destination’s signal in brackets after each entry in a wiring table’s Destination column. It is on by default; turn it off for narrower tables that show just the component and cavity. This only changes wiring tables on the canvas: the Connections view, destination labels and exports are unchanged.

Pinouts

Choose which side connector pinouts are shown from. Show pinouts from the Mating side (the default) draws the connector’s mating face; Harness side draws the back of the connector, where the wires go in, as a mirror image with the same cavity designations. A preview shows the result.

Show side labels writes Mating side or Harness side under every pinout. Both settings apply to pinouts on the canvas, in part details, in the pinout picker and in the PDF export.

Performance

Only render visible components on the schematic screen controls whether the schematic view skips drawing components that are outside the visible area. It is on by default and may help with performance on some devices, especially for large harnesses. Turn it off if components appear to pop in while panning or zooming.

Input

Input type

Forces the software to interpret scrolling for a specific input device.

Mouse - Scrolling zooms the canvas. Click and drag the middle mouse button to pan.
Trackpad - Scrolling pans the canvas. Pinch to zoom in and out.
Auto - Automatically detect the input device

Crosshair cursor

The Show crosshair cursor checkbox draws a horizontal and a vertical line through the cursor across the whole schematic or layout canvas, like the crosshairs in traditional CAD software. Use it to check that components line up with each other. Press H to toggle it while editing.

Hotkeys

A reference list of every keyboard shortcut and mouse action available in the editor. Mod is Cmd on macOS and Ctrl on Windows and Linux.

Part Libraries

Desktop App only. Lists the local .harnesslib part library files on this computer. Every library listed here is offered to each harness you open, alongside your cloud libraries, and works offline.

New library… - Creates a new .harnesslib file and adds it to the list.
Link existing… - Adds a .harnesslib file you already have, for example one kept in version control with your team.
Open / Show in folder / Remove from this app - Each library’s menu. Removing a library only takes it off this list; the file stays on your computer.

A library whose file can’t be found any more is marked Missing until the file is back or you remove it.
