HI! I'm new on shapeways and stuff so sorry if this has been asked a million times before, but I've scoured the site and i can't find an answer. so, I uploaded this ring design http://www.shapeways.com/model/542770/6b1f0c828e8e825235f73f b13ccc9f51 as an STL file. I modeled it in Pro Engineering... and with the normal rendering it looks fine and smooth, and when it gets converted to an STL file, all these weird angles appear on the edges of it. I know that STL files basically makes up the geometry with a whole bunch of triangles, but when it gets printed are the lines and edges still so harshly defined? and if they are, what can I do in order to fix it. I only model in Pro E... well, it's what I've learned so far in engineering school. kay thanks bye!
