	StringEnum	Helper class for working with 'extended' enums using StringValueAttribute attributes.
	StringValueAttribute	Simple attribute class for storing String Values
	Symbols	Symbols for dxf text strings.
	Transparency	Represents the transparency of a layer or an entity.
	XData	Represents the extended data information of an entity.
	XDataRecord	Represents an entry in the extended data of an entity.

Structures

	Structure	Description
	Matrix3	Represents a 3x3 double precision matrix.
	Vector2	Represent a two component vector of double precision.
	Vector3	Represent a three component vector of double precision.

Enumerations

	Enumeration	Description
	ClippingBoundaryType	Image clipping boundary type.
	CoordinateSystem	Defines the coordinate system reference.
	Lineweight	Represents the line weight of a layer or an entity.
	XDataCode	Defines the extended data code.

Remarks

The most relevant classes in the namespace

ClippingBoundary - Constructs from two or more 2D vectors Vector2, providing polygonal or rectangular clipping boundary for the drawing
XData - Extended data information of an entity. Main property is XDataRecord

Examples

Creating new document and loading existing DXF document

Copy

 1 public static void Main()
 2 {
 3    // your dxf file name
 4string file = "sample.dxf";
 5 // by default it will create an AutoCad2000 DXF version
 6 DxfDocument dxf = new DxfDocument();
 7 // an entity
 8 Line entity = new Line(new Vector2(5, 5), new Vector2(10, 5));
 9 // add your entities here
10 dxf.AddEntity(entity);
11 // save to file
12 dxf.Save(file);
13 bool isBinary;
14 // this check is optional but recommended before loading a DXF file
15 DxfVersion dxfVersion = DxfDocument.CheckDxfFileVersion(file, out isBinary);
16 // netDxf is only compatible with AutoCad2000 and higher DXF version
17 if (dxfVersion{DxfVersion.AutoCad2000}) return;
18 // load file
19  DxfDocument loaded = DxfDocument.Load(file);
20 }
