how to get blender stuff into .STL format.

Can somebody tell me how to get a set of blender meshes into .STL format (Stereo lithography)?



File -> Export -> STL


It turns out that file->export->stl is in only 2.34. I’m still using 2.27 because I prefer the old UI.

Well I suppose it;'s a good reason to upgrade to the newest version ;)_

thnx for the info.
