Custom Shape Libraries

Create your own reusable shape collections.

Creating a Library

1. Select shapes you want to include
2. Right-click → Add to Library
3. Choose an existing library or create a new one
4. Name your shape

Managing Libraries

Access library management from Documents → Shape library:

• Create new libraries
• Rename existing libraries
• Delete libraries (built-in libraries cannot be deleted)
• Export libraries as JSON files
• Import libraries from JSON files

Sharing Libraries

Export your custom library:

1. Go to Documents → Shape library
2. Select your library
3. Click Export
4. Share the .json file

Import a shared library:

1. Go to Documents → Shape library
2. Click Import
3. Select the .json file

Tips

• Right-click a shape on canvas → Save to Library to add it to a custom library
• After selecting a shape tool from the picker, click on the canvas to place it
• Use the search in the shape picker to find icons by name across all libraries
