In doing this tutorial I am "progressed" to modelling the front of the iphone. And again I have some bad areas in my mesh. I did succeed to solve some of those bad areas but have still some issues left. Who can help me with solving those issues ?

Still one issue left

  • $\begingroup$ Oei, jij fanatiekeling! Some to the right of nr. 2 you have a dubble edge. For 1 and 3, I dont really know what happened. Some how you also have multiple "doubles" in your mesh/object which is not good... Is it possible to go a few steps back in the tutoial and redo that part / or go back to an earlier save file where the problem has not yet occurred? $\endgroup$ – Abel Nov 29 '15 at 20:03

All of your issues are the result of the same problem: the subsurf modifier will give you unpredictable, and mostly ugly, results when using ngons (polygons with more than 4 vertices).

1 Delete this Ngon and reconnect the vertices forming quads.

2 Other ngon... add loop cuts to keep the topology consistent using quads.

3 Yet another ngon!:

4 You have vertices that are going past the axis of symmetry used by the mirror modifier. That's bound to cause you more errors down the line.

Scale them to 0 in the Z axis (SZ0)

  • $\begingroup$ thanks a lot. I could solve three of four issues I think (with your instructions). One issue lef (your number two). There I don't understand your instruction. I re-uploaded my file. Start already dreaming about n-gons ;) $\endgroup$ – Old Man Nov 29 '15 at 23:22
  • $\begingroup$ Now I understand your instruction for issue 2. Issue solved !!! Thanks Thanks !! $\endgroup$ – Old Man Nov 29 '15 at 23:28

    $\begingroup$ And put the Mirror mod. above the Subsurf mod. $\endgroup$ – Abel Nov 30 '15 at 19:31
