Generic Components

Add components that don’t exist in the library directly from the Harness Builder. Use category templates for quick schematic-style symbols, or upload your own image for a custom look.

Creating a Generic Component

  1. Open the Components floating panel by clicking the connector icon on the right side of the canvas, or press C
  2. Click the Create button in the panel header
  3. Select a category template from the dropdown (power supply, circuit breaker, relay, contactor, fuse, switch, push button, fan, motor, timer, PCB, etc.) to use a built-in schematic symbol, or start from scratch
  4. Set the number of positions for your component
  5. Optionally enter an MPN and click the magic wand button to auto-fill details from Digi-Key (manufacturer, description, datasheet, image)
  6. Keep the category template icon, or upload/paste your own custom image (SVG or PNG)

Editing a Generic Component

To modify a generic component after adding it to the canvas:

  • Right-click the component and select Edit Properties
  • Or click the tune icon in the component’s toolbar when selected

You can update the category, number of positions, part details, and custom graphics at any time.
