Hei, I’m new here, but I encounter some problems.  
I can not modify a lot of faces of my project (when you select a face and just drag it with the blue arrow). I think that the problem could been caused by the round off the edges, I suppose that they would become too small and sharp to be rendered.  
Any suggestions?
