Stereolithography STL file export plug-in for AutoCAD
STL Export for AutoCAD is a Stereolithography (.stl) file export plug-in for AutoCAD®. This plug-in gives AutoCAD the ability to export geometric data from AutoCAD to ASCII and Binary STL files.
AutoCAD already has a STLOUT command which exports a STL file. The STLOUT command is limited to 3D Solids which lie in positive space only (i.e. positive x, y and z). STL 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 STL file. These objects can lie anywhere in space. Quad faces are broken down into triangular faces and 3D Solids are tessellated into triangular faces. The level of tessellation can be controlled by adjusting the resolution slider in the STL Export for AutoCAD options dialog box. A lower resolution will yield coarse meshes (lesser faces), whereas a higher resolution will result in finer meshes (more faces).

STL Export for AutoCAD is very easy to use. Once installed, it must be loaded into the AutoCAD environment. 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 "STLExport" to the AutoCAD menu containing these newly added commands.
Below is the hardware, software and operating system requirements for AutoCAD plug-ins running on the Microsoft Windows platform.
- AutoCAD (32 Bit and 64 Bit): 2000, 2000i, 2002, 2004, 2005, 2006, 2007, 2008, 2009, 2010
- Operating System (32 Bit and 64 Bit): Windows XP SP2 or later, Windows Vista
- RAM: 1 GB (Recommended 2 GB)

Installation & Usage
Since STL 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 STL 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 "STLExport" submenu or type "STLExport" (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 STL file you wish to export. Truly, software made simple!
The 'STLExport' menu consists of the following commands:
The STLExport submenu
STL Export for AutoCAD comes with detailed documentation for each command as well as a tutorial to get you started in the shortest possible time. There is also an online version of the help file which you can view by clicking the link below.

The STL File Format
The STL file format is the Rapid Prototyping industry's standard data transmission format and is the format required to interact with stereolithography machines. Stereolithography files contain solids which are made up of 3 sided facets. STL files may be ASCII or binary data, although binary is far more common due to the resulting size of the CAD data when saved to the ASCII format. A STL file describes a raw unstructured triangulated surface by the unit normal and vertices (ordered by the right-hand rule) of the triangles using a three-dimensional Cartesian coordinate system. Many CAD systems are able to output the STL file format among their other formats, but very few have the ability to import STL files.

Sycode Software Licensing Terms
Our licenses are single computer licenses and are locked to each computer they are installed on. Basically, the license key is specific to the computer's Host ID (the MAC address of the computer), and will not work on another computer. The installer picks up the physical MAC address of the network card connected to the computer which is basically “Ethernet adapter Network Connect Adapter”. So unless you change your network card, the key will always work even if you reinstall your operating system. If your internal network is periodically assigning a different Host ID to your computer, then please find a solution for this with your IT department.
