Harness Connector

A placed Harness Connector


A Harness Connector object is an electrical drawing primitive. It is essentially a container to group various signals together to form a Signal Harness including buses and wires. A Harness Connector is defined by the Harness Type.


Harness Connectors are available for placement in the Schematic Editor only by clicking Home | Circuit Elements |  from the main menus.

A harness connector can also be defined textually in a Harness Definition File (*.Harness). Such a defined harness connector can only be placed in the design using the Place » Harness » Predefined Harness Connector command available from the Schematic Editor's right-click context menu.

Harness Connectors defined textually require the Locked; syntax. If the definition is not locked, the changes will not be saved since the software manages the Harness Definition Files automatically based on graphical instances of Harnesses.


After launching the command, the cursor will change to a cross-hair and you will enter Harness Connector placement mode. Placement is made by performing the following sequence of actions:

  1. Click or press Enter to anchor the tip of the Harness Connector.
  2. Move the cursor to adjust the size of the Harness Connector, then click or press Enter to anchor the corner and complete placement of the Harness Connector.
  3. Continue to place other Harness Connectors or right-click or press Esc to exit placement mode.

Additional actions that can be performed during placement – while the harness connector is still floating on the cursor, and before its tip is anchored – are:

  • Press the Tab key to access an associated properties dialog, from where properties for the harness connector can be changed on-the-fly.
  • Press the Alt key to constrain the direction of movement to the horizontal or vertical axis, depending on the initial direction of movement.
  • Press the Spacebar to rotate the harness connector counterclockwise or Shift+Spacebar for clockwise rotation. Rotation is in increments of 90°.
  • Press the X or Y keys to mirror the harness connector along the X-axis or Y-axis respectively.

While attributes can be modified during placement (Tab to bring up associated properties dialog), keep in mind that these will become the default settings for further placement.

Graphical Editing

This method of editing allows you to select a placed harness connector object directly in the workspace and change its size, shape or location graphically.

When a harness connector object is selected, the following editing handles are available:

A selected Harness Connector

  • Click and drag A to resize the harness connector in the vertical and horizontal directions simultaneously.
  • Click and drag B to resize the harness connector in the vertical and horizontal directions separately.
  • Ctrl+click and drag C vertically to change the location of the harness connector's tip.
  • Ctrl+click and drag C horizontally to resize the harness connector in the horizontal direction.
  • Click anywhere on the harness connector – away from editing handles – and drag to reposition it. While dragging, the harness connector can be rotated (Spacebar/Shift+Spacebar) or mirrored (X or Y keys to mirror along the X-axis or Y-axis respectively).
  • The Harness Connector Type text for a harness connector object can be edited in-place by:
    1. Single-clicking the text to select it.
    2. Single-clicking again (or pressing the Enter key) to enter the in-place editing mode. Sufficient time between each click should be given to ensure the software does not interpret the two single-clicks as one double-click (which would open the harness connector type's properties dialog).
    3. To finish editing in-place text, press the Enter key, or use the mouse to click away from the text.

An object that has its Locked property enabled cannot be selected or graphically edited. Double-click on the locked object directly then disable the Locked property to graphically edit the object.

Non-Graphical Editing

The following methods of non-graphical editing are available:

Via an Associated Properties Dialog

Dialog page: Harness Connector

This method of editing uses the following dialog to modify the properties of a harness connector object.

The Harness Connector dialog

The dialog can be accessed during placement by pressing the Tab key.

After placement, the dialog can be accessed in one of the following ways:

  • Double-click on the placed harness connector object.
  • Place the cursor over the harness connector object, right-click then choose Properties from the context menu.

Via the SCH Inspector Panel

Panel pages: SCH Inspector

The SCH Inspector panel enables you to interrogate and edit the properties of one or more design objects in the active document.


  1. The Harness Type option in the Harness Connector dialog defines the type of the Harness Connector. When a Harness Type is used within your project, the corresponding Harness Definition for this Harness Type is referenced.
  2. By default, newly-placed Harness Connectors are given the Harness Type Harness.
  3. The Harness Type can be hidden from view or moved to save space in your design. Enable the Hide Harness Type option in the Harness Connector dialog or select the Harness Connector, open the SCH Inspector panel, and enable the Hide Harness Type option. Alternatively, double-click on the Harness Type object (the text associated to the harness connector) and enable the Hide option in the associated Harness Connector Type dialog.
