DXFの生成

DXFを生成する方法

問題: DXFを生成する方法。

ヒント: これには、LINE、CIRCLE、ARC、TEXT、POINT、SOLID、3DFACE、およびPOLYLINEなどの異なるオブジェクトを使用して形状をレンダリングできます。その後、形状をエンティティとして追加するのを忘れないでください。

注: 私たちは、最初からDXFファイルを作成する機能を持っています。デフォルトではAC109ファイル形式を使用しますが、他のファイルバージョンを指定するオプションもあります。

例:

DxfImage dxfImage = new DxfImage();
//LINE, CIRCLE, ARC, TEXT, POINT, SOLID, 3DFACE and POLYLINE

//add line
CadLine line = new CadLine(new Cad3DPoint(0, 0, 0), new Cad3DPoint(100, 100, 100));
dxfImage.AddEntity(line);

//add circle
CadCircle circle = new CadCircle(new Cad3DPoint(50, 0), 10);
dxfImage.AddEntity(circle);

//add arc
CadArc arc = new CadArc(new Cad3DPoint(100, 0), 10, 45, 135);
dxfImage.AddEntity(arc);


CadText text = new CadText();
text.FirstAlignment = new Cad3DPoint(0, -50, 0);
text.TextHeight = 10;
text.DefaultValue = "text value";
dxfImage.AddEntity(text);


CadPoint point = new CadPoint();
point.CenterPoint = new Cad3DPoint(-10, -10, -10);
dxfImage.AddEntity(point);


CadSolid solid = new CadSolid();
solid.FirstCorner = new Cad3DPoint(200, 200, 0);
solid.SecondCorner = new Cad3DPoint(210, 200, 0);
solid.ThirdCorner = new Cad3DPoint(210, 220, 0);
solid.FourthCorner = new Cad3DPoint(200, 220, 0);
dxfImage.AddEntity(solid);

Cad3DFace cad3DFace = new Cad3DFace();
cad3DFace.FirstCorner = new Cad3DPoint(-200, 200, 0);
cad3DFace.SecondCorner = new Cad3DPoint(-210, 200, 0);
cad3DFace.ThirdCorner = new Cad3DPoint(-210, 220, 0);
cad3DFace.FourthCorner = new Cad3DPoint(-200, 220, 0);
dxfImage.AddEntity(cad3DFace);


CadPolyline polyline = new CadPolyline();
polyline.VerticesFollowFlag = 1;
var vertex1 = new Cad2DVertex() { LocationPoint = new Cad3DPoint(20, 0) };
var vertex2 = new Cad2DVertex() { LocationPoint = new Cad3DPoint(40, -40) };
var vertex3 = new Cad2DVertex() { LocationPoint = new Cad3DPoint(60, -40) };
dxfImage.AddEntity(polyline);
dxfImage.AddEntity(vertex1);
dxfImage.AddEntity(vertex2);
dxfImage.AddEntity(vertex3);
CadSeqend seqend = new CadSeqend();
dxfImage.AddEntity(seqend);

//Color example
CadLine lineColor = new CadLine(new Cad3DPoint(0, 0, 0), new Cad3DPoint(-100, 0, 100));
dxfImage.AddEntity(lineColor);
lineColor.ColorId = 15; //ACI color id

//polyline style example
CadPolyline polylineStyle = new CadPolyline();
polylineStyle.VerticesFollowFlag = 1;
polyline.StartWidth = 3;
polyline.EndWidth = 3;
var vertex1Style = new Cad2DVertex() { LocationPoint = new Cad3DPoint(-20, 0) };
var vertex2Style = new Cad2DVertex() { LocationPoint = new Cad3DPoint(-40, -40) };
var vertex3Style = new Cad2DVertex() { LocationPoint = new Cad3DPoint(-60, -40) };
dxfImage.AddEntity(polylineStyle);
dxfImage.AddEntity(vertex1Style);
dxfImage.AddEntity(vertex2Style);
dxfImage.AddEntity(vertex3Style);
CadSeqend seqendStyle = new CadSeqend();
dxfImage.AddEntity(seqendStyle);

dxfImage.Save(fileResult);
