Génération de DXF

Comment générer un DXF

Problème : Comment générer un DXF.

Conseils : Pour cela, vous pouvez utiliser différents objets pour rendre des formes telles que LINE, CIRCLE, ARC, TEXT, POINT, SOLID, 3DFACE et POLYLINE, après cela n’oubliez pas d’ajouter les formes en tant qu’entités.

Remarque : Nous avons la fonctionnalité de créer un fichier DXF à partir de zéro. Par défaut, nous utilisons le format de fichier AC109, mais avec l’option de spécifier une autre version du fichier.

Exemple :

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);
