STL Exporter for Revit 2012

The STL Export Add-In for Revit is designed to produce a stereolithography file (STL) of your building model.

The Revit team has developed a tool to export STL files from the Revit family of applications (Architecture, Structure, and MEP). STL is a popular file format for stereolithography used for rapid prototyping and computer aided manufacturing. An STL file describes the surface geometry of a 3D object.
