STL Export for AutoCAD is a plug-in for AutoCAD 2000, 2000i, 2002 and 2004. This plug-in gives AutoCAD the ability to export geometric data to ASCII as well as binary Stereolithography (STL) files.

AutoCAD already has a "STLOUT" command which exports STL files. But unfortunately it has some limitations. Firstly, it exports only 3D Solids and that too only one at a time. It does not export 3D Face, Polygon Mesh and Polyface Mesh entities which can very well be a part of a STL model. STL Export for AutoCAD addresses these issues. With STL Export for AutoCAD you can now export multiple 3D Solid, 3D Face, Polygon Mesh and Polyface Mesh entities to a single STL file.

STL Export for AutoCAD is very easy to use. It adds a new command to AutoCAD called "STLEX". Simply type "STLEX" at the AutoCAD command prompt and select the entities to export.
