Angular Dimension Example

This example demonstrates creating angular dimensions with layer-based colors. It shows how to define an angular dimension measuring the angle between two lines.

using System.Numerics;

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

// Define layers
var geoLayer = new Layer { Name = "TestLayer_Dimensions_Geometry", ColorARGB = AciColors.RosyBrown };
var dimLayer = new Layer { Name = "TestLayer_Dimensions", ColorARGB = AciColors.White };
session.AddLayer(geoLayer);
session.AddLayer(dimLayer);

// Angular dimension using layer colors
var center1 = new Vector3(50, 350, 0);
var p1 = new Vector3(100, 350, 0);
var p2 = new Vector3(70, 423, 0);

var line1 = new Line { StartPoint = center1, EndPoint = p1, LayerName = geoLayer.Name };
var line2 = new Line { StartPoint = center1, EndPoint = p2, LayerName = geoLayer.Name };
session.AddElement(line1);
session.AddElement(line2);

var angularDim1 = new AngularDim(
    plane: Plane3D.WorldXY,
    line1Guid: line1.Guid,
    line2Guid: line2.Guid,
    quadrantPoint: new Vector3(60, 360, 0),
    dimLinePos: new Vector3(60, 360, 0),
    textHeight: 4f)
{
    LayerName = dimLayer.Name,
    AngleFormat = AngleFormatType.DecimalDegrees
};
session.AddElement(angularDim1);

// 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

Angular dimensions measure the angle between two existing Line elements.
They require the GUIDs of the two lines (Line1Guid, Line2Guid) and points to define the dimension arc (QuadrantPoint, DimLinePos).
The AngleFormat property controls how the angle value is displayed (e.g., decimal degrees).
The dimension's color is inherited from its assigned layer.
