• 這種完美的控件用于開發工程，測量，CNC和工業相關的軟件。

• DXFReader的特點是熟悉的，直觀的，而且對于CAD開發人員來說，特別是易于使用的特性。在大多數情況下，他們不需要寫代碼。

• 針對于以下實體的顯示和操作，從rel.14到2007（版本v.u.23.1.01）與AutoDesk DXF全兼容，這些實體包括：3DFACE, ARC, ATTDEF, ATTRIB, CIRCLE, DIMENSION, ELLIPSE, IMAGE, INSERT, LINE, LWPOLYLINE, MTEXT, POINT, POLYLINE（包括凸多邊形，網狀折線和多面體網格）, RAY, SPLINE, 具有truetype 字體的TEXT，TRACE, XLINE。

• 顯示功能包括平移, 縮放(擴展，圖形界限，縮小，放大，向前，窗口，等)

• 每個實體和每個表項的完全控制提供一個對象集合用于表示每個繪圖元素。這是可能的，很少說明的是，這是為了檢索和處理每個繪圖信息并添加或移除任何實體項。例如下面的代碼將打印出在一個繪圖中的每條線的距離：

Dim Entity as DXFReaderEntity

With DXFReader1

 For Each Entity In .Entities

  If Entity.EntityType = "LINE" Then

   Printer.Print Sqr((Entity.X1 - Entity.X0) ^ 2 + (Entity.Y1 - Entity.Y0) ^ 2)

  End If

 Next Entity

End With

• 塊，尺寸規格，屬性和顏色的完全控制，都是使用已實施的默認的調色板對話框來設置AutoCAD Color Index值。

• 完全訪問DXF文件的HEADER變量來檢索和/或修改如單元格式，屬性模式，尺寸參數，擴展，圖形界限等信息。

• 具有不同縮放尺寸大小的光柵背景圖像的完全支持，使其能夠和矢量繪圖一起使用。

• 使用不同打印模式的全分辨率打印。能夠檢索和設置縮放尺寸大小，頁邊距，空白，渲染，旋轉，寬高比和選擇不同畫筆指定。

• 在不同版本中的完整的DXF文件的保存。它可以使用一個低版本讀取一個DXF文件并將其寫入。單個DXF塊，BMP，和WMF圖片的保存。

• 紅線功能用于添加信息到繪圖中而無需修改數據庫。

• 一個繪圖的一個實體的讀取用來合并到其他正在改變旋轉角度，縮放大小和變換的繪圖中。

• 網格，軸，圖形界限和基點的可視化。

• 選擇引擎。您可以選擇一個繪圖的實體，只需在該實體上簡單地按一下。

• 全上下文敏感的HtmlHelp

• 完全兼容于Microsoft Visual Studio.NET 2003/2005/2008, Microsoft Visual Basic 4.0, 5.0 和 6.0版本, Microsoft Office, Microsoft Visual C++, Microsoft Visual J++, Microsoft Visual FoxPro 6.0, Borland Delphi.

DXF is an acronym for Drawing eXchange Format. DXF is an ASCII replication of the contents of a drawing file enabling the interchange of files from one CAD system to another program. DXF import/export is supported by a wide variety of applications, ranging from CAD products to word processors, desktop publishing and illustration tools. The DXF CAD format has become the defacto standard in PC based CAD industry with many other CAD systems able to read and write this format too.

With DXFReader you can also retrieve every drawing information and every entity and easily perform data manipulation and/or analysis directly within your development environment.

Features

The following is a highlight of some of the major features of DXFReader:

• The ideal Control to develop engineering, surveying; CNC and industrial related software.
• DXFReader's features are familiar, intuitive, and easy to use especially for CAD developers. In most cases, they require no code.
• Full compliant with AutoDesk DXF from rel. 14 to 2007 (version v.u.23.1.01) for display and manipulation of the following entities: 3DFACE, ARC, ATTDEF, ATTRIB, CIRCLE, DIMENSION, ELLIPSE, IMAGE, INSERT, LINE, LWPOLYLINE, MTEXT, POINT, POLYLINE including bulged polylines, meshed polylines and polyfaces, RAY, SPLINE, TEXT with truetype fonts, TRACE, XLINE.
• Display functions including Pan, Zoom (Extents, Limits, In, Out, Previous, Window, etc.)
• Full control of every entity and of every tables entry providing collections of objects representing every drawing elements. It is possible, with few instructions, to retrieve and process every drawing information and add or remove any entry.
  For example the following code will print out the distance of every line in a drawing:

  Dim Entity as DXFReaderEntity
  
  With DXFReader1
  
   For Each Entity In .Entities
  
    If Entity.EntityType = "LINE" Then
  
     Printer.Print Sqr((Entity.X1 - Entity.X0) ^ 2 + (Entity.Y1 - Entity.Y0) ^ 2)
  
    End If
  
   Next Entity
  
  End With
   

• Full control of blocks, dimensions, attribute and color using the AutoCAD Color Index with implemented default palette dialog.
• Full access to every HEADER variable of the DXF file to retrieve and/or modify information like units format, attribute mode, dimensioning parameters, extensions, limits and so on.
• Full support of background raster image with different scaling to use together vectorial drawings.
• Full resolution printing using different printing modes. It is possible to retrieve and set scaling, margins, origin, rendering, rotation, aspect ratio and select different pen assignments.
• Saving of full DXF file in different versions. It is possible to read a DXF file and write it using a lower version. Saving of single DXF block, of BMP and WMF pictures.
• Redlining functions to add information to the drawing without modifying the database.
• Reading of the only entities of a drawing to merge together other drawings changing rotation, scaling and translation.
• Visualization of grid, axes, limits and base point.
• Pick engine. You can select a drawing's entity simply clicking on it.
• Full context sensitive HtmlHelp.
• Full compatible with Microsoft Visual Studio.NET 2003/2005/2008, Microsoft Visual Basic 4.0, 5.0 and 6.0, Microsoft Office, Microsoft Visual C++, Microsoft Visual J++, Microsoft Visual FoxPro 6.0, Borland Delphi.
