Description: ZwCAD 2006 is a great alternative for AutoCAD with native DWG version from 2.5 to 2006. ZwCAD 2006 can read, save and edit the files produced by AutoCAD (2.5-R14-2006) and the other way round. It is the intelligent choice for architects, engineers, designers, and virtually any professional who createsprofessional 2D and 3D CAD drawings. ZwCAD can be customized with lisp, C++ (ADS), and VBA (Visual Basic for Application).
Native DWG/DXF Support (From 2.5-2006) 
ZwCAD's native file format is .DWG, so when you open an existing DWG file there's no file conversion and no data loss. ZwCAD also provides a high degree of compatibility with the AutoCAD command set, as well programming API's such as AutoLISP and ADS. That means you can get to work immediately using the DWG files, AutoCAD commands and applications you rely on.
Highly compatible with AutoCAD
1. Native DWG support, DWG files (includeing AutoCAD R11 to 2006)
• ZwCAD allows users to read, write, modify and save any drawings existing in AutoCAD from R14 to 2006 without conversion. And since drawings are natively created in DWG, it can be shared between ZwCAD and AutoCAD without data loss.
2. Support for AutoCAD command line
• By clicking the right button of a mouse on the toolbar then selecting [command bar] from the shortcut menu, or pressing [F12], the command line appears as in AutoCAD. Furthermore, users are able to use AutoCAD commands and thousands of programs coded by AutoLISP, ADS, and VBA.
3. AutoCAD menu's, fonts and symbols
• ZwCAD supports AutoCAD menus (.MNU), scripts (.SCR), dialog boxes (.DCL) and fonts (.SHX). So you can easily transfer custom AutoCAD environments into ZwCAD and coutinue working in your favorite drafting environment all the same.
4. Raster image display
• ZwCAD supports the raster image files such as scanning files or photos on drawings. Supported formats are BMP, GIF, JPG, TIF, PCX and so on. In addition, it can copy to DWG image directly.
5. Digitizer Support
• Many drafting departments have established routines using digitizers within their CAD workgroup. For CAD departments that utilize digitizers as input devices. ZwCAD supports both tablet mode for tracing and the use of tablet menus for command input.
6. 3D surface commands
• ZwCAD's sophisticated 3-D capability allows creation of high-quality 3-D models. You can display them as wireframes, with hidden lines removed, or with surface shading.
Productivity Features
1. Drawing recover and audit
2. Tabs for paper-space layouts
• ZwCAD supports tabs at the bottom of the drawing area for quickly switching between different layouts.
3. Properties Palette & Properties bar
• AutoCAD® like interface for properties modification (Color, Layer, Text height, Lineweights, Line Type, Geometry etc.), and AutoCAD® like Toolbar for Layers, Linetypes, Colors and Line Width management.
4. Advanced Layer Properties Manager
• AutoCAD® like interface for layer management, to freeze or unfreeze, lock or unlock, and modify other properties.
5. Powerful MTEXT Edition
6. AutoCAD® like interface of Dimension Style Manager
7. Lineweight for Display and Printing
8. Real time Pan & Zoom in Print Preview
9. ActiveX support includeing in-place editing
• ZwCAD provides in-place Editing of Microsoft objects written in Microsoft Word, Microsoft Excel. In-place Editing enables you to share data with the different users and the programs. For instance, ZwCAD drawings can be inserted in Microsoft Word or Excel documents and can includee Word or Excel documents. Furthermore, double-clicking enables data editing.
10. Xref Manager
• A comfortable interface for the management of external references.
11. Express tools with multifunctions
12. Work with multiple open drawings (MDI)
• ZwCAD can open and edit up to 255 files at once (MDI). This powerful feature allows CAD professionals to review two or more drawings with one session. Furthermore, among the opened drawings, users can copy, cut, and paste form one drawing to another. It makes your work more efficiency.
13. Drawing Explorer for managing layers, blocks, line types, and more
• The Explorer of ZwCAD has the similar interface to Windows Explorer so that users can find layers, line types, text styles, blocks, view, coordinates(UCS) and so forth in a drawing and manage them very easily. In other words, necessary elements from opened drawings can be copied or moved to other drawing or can be removed.
14. Real Time Pan & Zoom
• ZwCAD allows users to work with their drawings using Real Time Pan and Zoom. It can makes view and display drawing files easier and more productive.
15. Unlimited Undo/Redo
• ZwCAD lets you "Undo and "Redo" an unlimited number of editing actions.
16. Visual Basic for Application (VBA)
• ZwCAD not only supports AutoLISP(includeing DCL files) but also offers the power of Microsoft Visual Basic for Applications(VBA).
17. Script recorder
• Like a macro in Word, a script mimics what you type, includeing command names, options and coordinates
18. Visual customization of menus and toolbars
• ZwCAD supports AutoCAD menus (MNU), dialog boxes (DCL), fonts (SHX),
scripts (SCR), and symbol libraries, so you can easily transfer custom AutoCAD environments into ZwCAD and continue working in your favorite drafting environment. ZwCAD menus, function keys, and command aliases are able to be redefined by using a mouse and toolbars being changeable by drag-and-drop.
What's new in ZwCAD 2006?
* Speed up
Speed performance increased 120% to handle larger drawings.
* Compatibility enhancement
ZwCAD 2006 makes big progress in saving and opening DWG files. It will be easier to open your existing AutoCAD DWG file (2.5-2006) and other way round.
* Polar tracking and Object snap tracking support
Polar tracking and object snap tracking help you draw objects at specific angles or in specific relationships to other objects. When you turn on polar tracking and object snap tracking, temporary alignment paths help you create objects at precise positions and angles. You will discover techniques that make specific design tasks easier.
Polar tracking and Object snap tracking
* True color system
True colors can be viewed, edited and printed in NEW version.
* Export objects as DXF file
You can export your drawing (a part or whole drawing) as a DXF. It allows you to remove extraneous material from drawing files.
* Quick Dimension
You can use Quick Dimension (QDIM) to mark multiple objects' dimensions at one time or edit existing dimensions
* QLEADER support
Use QLEADER to quickly create leaders and leader annotation. You can specify leader annotation and annotation format, set the location where leaders attach to multiline text annotation, limit the number of leader points, constrain the angle of the first and second leader segments.
* Text preview
Text Style can be previewed in the Text Style dialog box. When you create a Text object, the screen will display the text what you have enter on the command line.
* Updated Purge feature
The Purge dialog box displays items that can be purged in a drawing.
* Express Tools
The new version contains more than 80 express too to accelerate your drafting speed.
* Updated Undo/Redo system
In the NEW version, Undo/Redo system will be much stable and reliable than before.
* Draworder
You can use DRAWORDER to change the draw order (which is the display and plotting order) of any objects.
* General functionality improvements
More than 300 unspecified bug-fixes and functionality improvements have been made in ZwCAD 2006 relate to dimension, Font styles preview, Express tool, layout, OLE--etc.
