STL import problem


recently i’ve updated Rhino to the last SR and since that moment everytime I insert/import/open an STL file it doen’t work properly: i doesn’t give me any error but no geometry is imported.

I’ve tried it with several different STL files

Any idea?

I haven’t heard of this from any other users and haven’t seen it myself. Are you using SR12 or SR13? Also, have you checked different display modes? You might have mesh wires off in wireframe for example making it look like nothing is there. If that’s not involved, can you post an stl that doesn’t open?
