Features Formboard

FormboardEnterprise Feature

Formboard mode turns the Layout view into a 1:1 physical scale drawing of your harness. The lengths you see on the canvas correspond directly to real-world measurements.

When formboard mode is on, the layout view changes to support physical assembly: snapping to grid is removed, bundles bend with a real corner radius, and bundles can be set to their actual lengths.


Formboard layout is an Enterprise feature. You need an Enterprise subscription to enable it and to edit a formboard harness. Without Enterprise you can still open and view a harness that is already in formboard mode, but the layout is read-only. See the Plans page or visit app.harness.design/upgrade  to upgrade.

Turning on Formboard Mode

  1. Open Main MenuSettingsFormboard.
  2. Turn on Use formboard for layout.

The layout view immediately re-renders at 1:1 scale, centered on the formboard panel.

Formboard Settings


Panel size

The physical size of a single panel. Panels are the sections your formboard is divided into.


  • Preset - Choose a standard panel size (A4, A3, A2, A1) or Custom to enter your own dimensions.

  • Orientation - Set a preset panel to Landscape or Portrait. (Hidden when the preset is Custom.)

  • Width / Height - The exact panel dimensions. Editable only when the preset is set to Custom; otherwise they follow the chosen preset and orientation.

Panel grid

Arranges multiple panels side by side in a grid to make up the full formboard. The overall board size is the panel size multiplied by the grid.


  • Rows - Number of panels down (1–64).
  • Columns - Number of panels across (1–64).

Default bend radius

The default corner radius applied where a bundle bends. You can override this for individual bundles — see Changing the Radius of a Bundle.

Scale

The physical length represented by a single canvas pixel. This effectively changes how large the component previews and labels are compared to the board.

Setting a Bundle to 1:1 Scale

Bundles that are not to scale, or that have no set length, are drawn as yellow lines with black dashes so you can spot them at a glance.

There are a few ways to make a bundle’s drawn length match its set length so it renders to scale — adjust one at a time, or set the whole harness at once.

Use the match button

Whenever a bundle isn’t to scale, a yellow button appears on its length label. Click it and the bundle’s path is automatically adjusted so it is drawn at exactly its set length.


Drag a component into place

As you drag a component, a blue line previews where the connected component needs to be placed for the bundle to be to scale. The component snaps to that location. When the bundle is to scale, the line turns green.


When you edit a bundle’s length, the layout is automatically adjusted so the bundle is drawn to scale at the new value.

Set the whole harness to scale at once

A Set all bundle lengths to scale button in the controls at the bottom-right of the layout view does the whole harness in a single step: it moves components so that every bundle is drawn at its set length, exactly as if you had clicked the match button on each one.

Changing the Radius of a Bundle

right-click a bundle and set a value in the Radius field to change how tightly that bundle bends. Leave it empty to fall back to the Default bend radius from the formboard settings.


Bending Branches

Drag a single branch point and the entire branch connected to it moves with it — every component keeps its position and angle relative to that branch point, so the whole section swings as one rigid unit. Use this to bend and reposition entire runs of the harness at once.


To move connected components without rotating them, select them all with a click-and-drag box and move them together — dragging a multi-node selection translates only, with no rotation.

Exporting your Formboard

From Main MenuExport, a formboard harness gains an extra Formboard Panels option.

It exports a PDF with one page per panel in the grid, each page sized to your panel size and drawn to scale. Print the pages, lay them out in the same grid arrangement, and build the harness directly on top — for example, an A3 panel with a 2 × 4 grid prints as 8 to-scale A3 pages.

The number of pages equals the Rows × Columns set under Panel grid. The standard ExportLayout PDF still renders the whole formboard onto a single 1:1 page.
