Export ArchiCAD Model to STL Format
Support for STL file format (Stereolithography) is built into ArchiCAD 17: you can directly save the ArchiCAD model as an STL file. An STL file carries only the surface geometry of a 3D model, divided into triangles, without any additional information (e.g. color, material).
You can also open or merge an STL file directly to ArchiCAD.
The format is usually used for rapid prototyping, 3D printing, and computer-aided manufacturing.
