DXF的生成

如何生成DXF

问题： 如何生成DXF。

提示： 为此，您可以使用不同的对象来渲染形状，例如LINE、CIRCLE、ARC、TEXT、POINT、SOLID、3DFACE和POLYLINE，之后不要忘记将形状添加为实体。

注意： 我们具有从头创建DXF文件的功能。 默认情况下，我们使用AC109文件格式，但可以选择指定其他文件版本。

示例：

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);
