Class ElementInstance

An instance of an element in the model. Instances point to one instance of a type, but have individual ids and transforms.

Examples
// Create a test user element.
var profile = new Profile(Polygon.Rectangle(1.0, 1.0));
var material = new Material("yellow", Colors.Yellow);
var line = new Line(Vector3.Origin, new Vector3(5, 5, 5));

// Set the isElementDefinition parameter to true,
// so the element is considered an instance definition.
var testUserElement = new TestUserElement(line, profile, material, isElementDefinition: true);

// Create instances of that element
// with varied transforms.
var attractor = new Vector3(30, 20);
for (var x = 0.0; x < 50; x += 1.5)
{
    for (var y = 0.0; y < 50; y += 1.5)
    {
        var loc = new Vector3(x, y);
        var d = loc.DistanceTo(attractor);
        var s = d == 0 ? 1 : 5 * Math.Sin(1 / d);
        var t = new Transform();
        t.Scale(new Vector3(s, s, s));
        t.Move(loc);
        var instance = testUserElement.CreateInstance(t, $"Test User Element {x}:{y}");
        this.Model.AddElement(instance);
    }
