Circle Example

This example demonstrates creating circles with layer-based colors. It shows how to set up layers and create circles with styling inherited from their layer.

using CadSDK;
using CadSDK.Elements;
using CadSDK.Enums;
using CadSDK.Geometry;

// Create a drawing session
var session = new DrawingSession
{
    ExportFormat = ExportFormat.DWG,
    CadVersion = CadVersion.Cad2018
};

// Define layers
var circleLayer = new Layer { Name = "TestLayer_Circle", ColorARGB = AciColors.Cyan };
session.AddLayer(circleLayer);

// Circle using layer color
var circle = new Circle(
    plane: Plane3D.WorldXY,
    center: new Vector3(20, 0, 0),
    radius: 10f)
{
    LayerName = circleLayer.Name
};
session.AddElement(circle);

// Export the drawing
// You can signup and get your free API key
string apiKey = "your-api-key"; // Get your free API key from the dashboard
string outputPath = "drawing.dwg";
await session.ExportAndSaveAsync(apiKey, outputPath);

Key Points

Circles are defined by their center point and radius.
Center points can be positioned in 3D space using Vector3 coordinates.
The circle's color is inherited from its assigned layer.
