Working with Libraries ​

LoomCAD provides access to component libraries to speed up your design workflow. You can use built-in libraries, fetch data from DigiKey, or create your own library templates.

Library = Drawing Template

LoomCAD libraries are more than part catalogs. Each library item is a complete drawing sheet that can contain multiple components, bundles, wires, and annotations. This lets you create reusable assemblies and sub-harness templates, not just single components.


Built-in Libraries ​

LoomCAD includes libraries for common components:

  • Connectors
  • Wires
  • Pins
  • Bundles

Using the Library Panel ​

  1. Open the Side Menu
  2. Click the Library tab
  3. Browse categories or use the search box
  4. Drag a component onto the canvas

Fetching Properties ​

If you have a component on the canvas that needs properties:

  1. Select the component
  2. Open the Inspector
  3. Click Fetch
  4. Choose a library item
  5. Select Merge (add properties) or Replace (overwrite all)

DigiKey Integration ​

DigiKey provides access to millions of real electronic components with specifications, images, and datasheets.

Searching DigiKey ​

  1. Open the DigiKey panel from the Side Menu
  2. Enter a search term (part number, description, or keyword)
  3. Browse results with component photos and categories

Viewing Component Details ​

  • Click a component to see its specifications
  • Click View on DigiKey to open the full product page
  • Click View Datasheet to see the PDF datasheet

Importing to Your Design ​

Method 1: Fetch to Existing Component ​

  1. Select a component on your canvas
  2. In the DigiKey panel, find the desired part
  3. Click Copy to Clipboard
  4. In the Inspector, click Fetch and paste

Method 2: AI-Assisted Creation ​

  1. Find your component in DigiKey
  2. Click Copy to Clipboard
  3. Open AI Chat
  4. Add the Inspector context badge
  5. Ask: "Create a connector using this DigiKey component"

Search History ​

DigiKey searches are cached for faster access. Recent searches appear in the search dropdown.


Creating Library Elements ​

Add your own components to libraries for reuse.

Creating a Component Template ​

  1. Create a component with all desired properties
  2. right click click the component
  3. Select Add to Library
  4. Choose the destination library
  5. Enter a name and description

Creating a Wire Template ​

  1. Create a wire with the desired properties (color, gauge, etc.)
  2. right click click the wire
  3. Select Add to Library

Managing Libraries ​

Access library management from the Side Menu:

  • Create new libraries
  • Edit existing elements
  • Delete unused items
  • Import/export library files

Tips ​

  • Use DigiKey for accuracy - Real part numbers ensure correct specifications
  • Build a project library - Add frequently used components to your project's library
  • Share libraries - Export libraries to share with team members
