Polylineler olarak dikdörtgen oluştur ve dolgulu hale getir

Polylineler olarak dikdörtgen oluştur ve dolgulu hale getir

Sorun: Polylineler olarak dikdörtgen oluşturma ve dolgulu hale getirme (CADNET-1351).

İpuçları: Bunu yapmak için bir CadLwPolyline oluşturun ve ona nokta koordinatları ekleyin, renk ile çalışmak için CadHatch kullanın ve bağlantı kurmak için CadEdgeBoundaryPath’ı kullanın, açılarla çalışmak için CadHatch kullanın ve desen için CadHatchPatternData kullanın.

Örnek:

CadLwPolyline polyline = new CadLwPolyline();
polyline.Coordinates = new List<Cad2DPoint>();
polyline.Coordinates.Add(new Cad2DPoint(-5d, -5d));
polyline.Coordinates.Add(new Cad2DPoint(-5d, 10d));
polyline.Coordinates.Add(new Cad2DPoint(20d, 10d));
polyline.Coordinates.Add(new Cad2DPoint(20d, -5d));
polyline.Flag = CadLwPolylineFlag.Closed;
polyline.ConstantWidth = 0.1;
