I’m trying to create a custom shape that only has two link points, similar to “DC Voltage Source 1” in the “Circuit Diagrams” → “Power Sources” library.  Link points are circled in green.
 

When I try to create a custom shape, I can add link points just fine.  There are two below in my custom shape in the corners (because I am debugging right now), and they are circled in green.  These appear when I am drawing a line.

The trouble is, there are four points that show up by default, and I can’t figure out how to get rid of them.  They behave differently from the link points above and show up whenever I hover the cursor over my custom shape.

What are these four default points, and how can I modify the custom shape definition to remove them?  The “DC Voltage Source 1” shape from Lucid’s library doesn’t have them, so it must be possible.  I just can’t figure it out from the documentation.

Here’s “library.manifest” for my custom shape:

{
    "name": "Electrical Symbols",
    "shapes": "
        {
            "shape": "diode",
            "name": "Diode",
            "defaults": {
                "width": 40,
                "height": 20
            }
        }
    ]
}

Here’s “diode.shape” for my custom shape:

{
    properties: c],
    locked: j'aspectRatio'],
    style: {
       fill: { type: 'color', color: '#00000000' },
       stroke: { color: '#000000', width: 2},
       rounding: 0
    },
    geometry:  
        {
            type: 'path'
            path: 'M 0 0.5 L 1 0.5'
        },
        {
            type: 'path',
            "path": 'M 0.25 0 L 0.25 1 L 0.75 0.5 Z'
        },
        {
            'type': 'path',
            'path': 'M 0.75 0 L 0.75 1'
        }    
    ],
    linkpoints:  
    	{x: 0, y: 0},
        {x: 1, y: 1}
    ],
    bounds: {
      x: 0.5,
      y: 0.5,
      w: 1.0,
      h: 1.0,
      anchor: 'center',
      absolute: 'false'
    }
}

Thanks,

Ben
