This is a Belt Buckle for a cockpit and the openings for the top and bottom seem to be showing where I subdivided the mesh, it isn’t smooth enough. The waves on the to buckle and bottom buckle have these triangular lines coming off them, I would like to know how to simply remove these unnatural lines to make it look straight and flat. 
Edit: I must have hit Ctrl+Z when I was posting this, took out a lot of what I wrote. :-?
What lines? I can’t even tell where the opening is. Need more info bro.
Nobody Can help me?
You should post a wire. Some suggestions:
- Your modelling is probably not so good. You should try and have only quads in your modell.
- Use multiple loop cuts or creases for the edges, if you you want sharper edges.
K, this is what happens when you hit Set Smooth. You need to go in and re-arrange your faces and edges so that one vertice doesn’t have tons of edges going into it. Like… go along your inside row of vertices, and remove the uneccesary ones. Why have 4 verticies going along a straight line when 2 will do? Try your best to get the same amount of vertices on the inside as the outside. Once you get them under control, go to edge select mode and start making the faces and checking the results and fixing things.
Or you can start over and make it simpler, which is what i do a lot.
This happens majorly when you use curves to model then convert the curve to mesh. If you can keep it a curve, then it’s wonderful.
Hope this helps.
Yeah, I already restarted on a different design. I just wanted to know if I actually had to do it manually. Thanks for help though. I know what was causing it, the top was subdivided twice and the rest was primitive.
Subdivided twice?
If that was for creasing there’s a much easier way, just select the edges you want to crease and find “crease edges” in the edge menu.
Perhaps I should humble myself and redo Noob to Pro… erm… What’s creases?
to ‘crease’ an edge select it then use shift-e ,a crease value of 0 has no crease a value of 1 is full crease , crease is as it sounds, like if you where to crease a peace of paper it would have a sharp edge.
Learned my Blender Tibet of the Day… HEEEYYY that’s not a bad idea!
Btw, why isn’t it moving anything? I’ll STFU now, just figured it out.
