# Edge

A geometry edge entity. When the edge is not connected to any faces it is considered to be a wire.

## Example

application = cf.Application.GetInstance()
project = application:NewProject()

-- Create geometry which contains edges/wires

polyline = project.Contents.Geometry:AddPolyline({cf.Point(0, 0, 0), cf.Point(1, 1, 1), cf.Point(1,0,0)})

-- Remove the first wire from the polyline

polyline.Wires["Wire1"]:Delete()

## Inheritance

The Edge object is derived from the TopologyEntity object.

## Usage locations

The Edge object can be accessed from the following locations:
