VTK Export for AutoCAD 1.0

VTK Export for AutoCAD 1.0 is designed as a powerful tool that can allow you to export geometric data from AutoCAD to ASCII and Binary VTK files. VTK Export for AutoCAD extracts facet data from 3D Solids as well as 3D Face, Polygon Mesh and PolyFace Mesh objects in the active AutoCAD drawing and exports it to a VTK file. These objects can lie anywhere in space. 3D Solids are tessellated into triangular faces.

Installation & Usage:

Since VTK Export for AutoCAD is a plug-in for AutoCAD, it must be loaded into the AutoCAD environment before it can be used. Please follow the simple instructions in the VTK Export for AutoCAD ReadMe document which is copied into the installation folder. After you have loaded the plug-in file into AutoCAD, simply click on the menu items in the "VTKExport" submenu or type "VTKExport" (without quotes) at the AutoCAD command prompt and press "Enter". This will bring about the "File Open" dialog box from where you can select the VTK file you wish to export. Truly, software made simple!

The 'VTKExport' menu consists of the following commands:

• VTKExport - Exports a VTK file
• VTKExportHelp - Displays the VTK Export for AutoCAD help file
• VTKExportRegister - Registers your copy of VTK Export for AutoCAD
• VTKExportAbout - Displays the VTK Export for AutoCAD About box

The VTK File Format:

The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing, and visualization used by thousands of researchers and developers around the world. VTK consists of a C++ class library, and several interpreted interface layers including Tcl/Tk, Java, and Python. The Toolkit stores geometric data in a file format known as VTK. Very few CAD applications have the ability to read and write VTK files.

Major Features:

1. VTK Export for AutoCAD  extracts facet data from 3D Solids as well as 3D Face, Polygon Mesh and PolyFace Mesh objects in the active AutoCAD drawing and exports it to a VTK file. These 3D Solids are tessellated into triangular faces.
2. The level of tessellation can be controlled by adjusting the resolution slider in the VTK Export for AutoCAD options dialog box.
3. A lower resolution will yield coarse meshes (lesser faces), whereas a higher resolution will result in finer meshes (more faces).
4. VTK Export for AutoCAD is very easy to use. Once installed, it must be loaded into the AutoCAD environment.
5. There are simple instructions for this in the ReadMe file. Once loaded it adds new commands to AutoCAD's existing commands and a new submenu called "VTKExport" to the AutoCAD menu containing these newly added commands.
