 ## Description
-netDxf is a .net library programmed in C# to read and write AutoCAD dxf files. It supports AutoCad2000, AutoCad2004, AutoCad2007, AutoCad2010,  AutoCad2013, and AutoCad2018 dxf database versions, in both text and binary format.

 The library is easy to use and I tried to keep the procedures as straightforward as possible, for example you will not need to fill up the table section with layers, styles or line type definitions. The DxfDocument will take care of that every time a new item is added.
 
-If you need more information, you can find the official dxf documentation [here](https://help.autodesk.com/view/OARX/2019/ENU/?guid=GUID-235B22E0-A567-4CF6-92D3-38A2306D73F3).

 {

+	// your DXF file name
 	string file = "sample.dxf";

 	// an entity
 	Line entity = new Line(new Vector2(5, 5), new Vector2(10, 5));
 	// add your entities here
-	dxf.AddEntity(entity);
+	doc.AddEntity(entity);
 	// save to file
-	dxf.Save(file);

 All entities can be grouped.
-All entities and table objects may contain extended data information.
+All DXF objects may contain extended data information. 
 AutoCad Table entities will be imported as Inserts (block references).
 Both simple and complex line types are supported.
 The library will never be able to read some entities like REGIONs, SURFACEs, and 3DSOLIDs, since they depend on undocumented proprietary data.

 ## Change history
 
-### [2020/08/18]
-* The public classes PolylineVertex and PolyfaceMeshVertex can contain extended data information XData, but they will not be saved in the DXF AutoCad crashes if they are.
-* Deleted the AciColor methods ToTrueColor and FromTrueColor, they have no use outside the DxfWriter and DxfReader classes. 
-
-### [2020/08/13]
+### [2.4.0 - 2020/08/20]
 * Added US Survey Feet, US Survey Inches, US Survey Yards, and US Survey Miles to the DrawingUnits.
-
-### [2020/08/11]
-* The DxfDocument class derives from DxfObject for convenience of this library not because of the DXF structure. It can contain external data information XData, but it will not be saved in the DXF.
-* (fixed) Table collection handles that are saved in the DXF OBJECTS section were not preserved.
-* (fixed) The RasterVariables object didn't have an owner.
-
-### [2020/08/10]
 * All classes derived from DxfObject can contain XData (extended data).
 	The TextStyles and ShapeStyles extended data information will be combined into the DXF STYLE table.
-* Deleted the IHasXData interface, it is not needed anymore.
-* The RasterVariables object is always saved, regardless if the document contains images or not.

+* Removed the IHasXData interface, it is not needed anymore.
+* Removed the AciColor methods ToTrueColor and FromTrueColor, they have no use outside the DxfWriter and DxfReader classes. 
 * Removed the MaxCapacity limits from the TableObject collections, except for layouts that it is 256 = 255 (paper space) + 1 (model space) exceeding this limit may crash AutoCad.
 	According to the AutoCad ActiveX documentation there is no limit, therefore the DXF code 70 maximum number of entries in table is obsolete, it represents a 16-bit integer value. 
 * Removed the MaxCapacity property from the TableObject collections.

-### [2020/08/04]
+* The RasterVariables object is always saved, regardless if the document contains images or not.
+* Added a check for the binary data record of the extended data. It cannot exceed 127 bytes, if needed divide it into multiples XDataCode.BinaryData records.
+* Added the main Viewport of the Layout, that was deleted in v2.3.0.
+* Added Swap method to the MathHelper class.
+* The block description is now loaded and saved to the DXF.
+* Removed the scale restrictions for the complex linetype segments. Even thought I would recommend to always use values greater than zero, you might not get the desired results.
+* Renamed LeaderPathType.StraightLineSegements to LeaderPathType.StraightLineSegments.
 * Renamed DxfObjectCode.LightWeightPolyline to DxfObjectCode.LwPolyline.
 * Renamed SubclassMarker.LightWeightPolyline to SubclassMarker.LwPolyline.
 * Force the use of the ASCII.WindowsCodePage encoding in the DxfReader class, just for cases where there was a problem reading the codepage from the file.
+* Misspelling corrections.
+* (fixed) Table collection handles that are saved in the DXF OBJECTS section were not preserved.
+* (fixed) The RasterVariables object didn't have an owner.
 * (fixed) Index to RGB color equivalent in the AciColor class.
 * (fixed) The FrozenLayers list of the Viewport entity cannot contain null items or layers that belong to different documents.
 * (fixed) When an open LwPolyline is converted to a set of vertexes (PolygonalVertexes method) the last vertex will not be welded to the first if they fall inside the defined threshold.

-* Additional change related to pull request #150. Force the use of the ASCII.WindowsCodePage encoding in the DxfReader class, just for cases where there was a problem reading the codepage from the file.
-
-### [2019/12/19]
 * (fixed) Error when trying to copy to clipboard inside AutoCAD for DXF files saved with netDXF that contains the header variables $INTERFEREOBJVS and $INTERFEREVPVS, since this variables refer to visual style information that netDxf does not save. This variables will not be loaded in case they appear in a DXF.
 * (fixed) After loading a DXF the layouts associated blocks will be renamed to strictly follow *Paper_Space, *Paper_Space0, *Paper_Space1,... 
 * (fixed) Transforming an ellipse might not show the correct result under special circumstances.

-### [2019/09/09]

 * (fixed) The MathHelper method NormalizeAngle will not round almost zero angles automatically.

 * (fixed) The DimensionStyle FitDimLineInside (DIMSOXD value) was used incorrectly, when it was true is should be false and vice versa.

-* (fixed) When a Block is created form a DxfDocument or DXF file, any Hatch entity that it may contain will have its associative property set to false.
-          This will avoid problems when the same entity its associated to multiple hatches, or when any of any of its paths is defined by the intersection of several entities.
