first time here.

Alrighty, I'm quite new to 3D model design in Blender, but I have a little problem with my book model. The mesh is fine (I think). But there are a good few points where the text mesh goes wrong for some weird reason. If you need to know which version of Blender I'm using, it's Blender 2.69.

When I apply the "subdivision surface" modifier and set the subdivision render to 2, the faces go in and deform in certain areas. As far I'm not sure what is wrong at this point. I've taken two pictures just in case you need them.

Take note that I'm still unaware of some certain tools and common knowledge in Blender, go easy on the in depth reasons and fix details. Just simplify it please :)

    $\begingroup$ The one on the top looks like it's because of the four triangles. The one on the side might be because of an internal face, but it's hard to tell. Is it possible you could you upload your .blend? $\endgroup$ – gandalf3 Jul 19 '14 at 6:36
  • $\begingroup$ I don't think so, I can email it to you though. $\endgroup$ – HighMaster Jul 19 '14 at 7:12

    $\begingroup$ To upload .blend files you can use PasteAll.org. It accepts images, .blend, and .py. After it uploaded there, you copy the URL in the address bar and paste the address here. Since you are new to this site, there may be a restriction on posting links. I'm not sure about this last part. $\endgroup$ – MarcClintDion Jul 19 '14 at 21:14

You have some issues with the topology:

  • Extra edges on the large inner-top face, creating n-gons (also see this question):

    enter image description here

    To fix them, select them and press Delete > Edges.

  • Extra vertices on the edges, also creating n-gons:

    enter image description here

    To fix them, select them and press Delete > Dissolve vertices.

  • Internal edges on each corner:

    enter image description here enter image description here

    To fix them, select them and press Delete > Edges.

  • Double vertices one of the corners:

    enter image description here

    To fix them, either merge them manually, or select everything (or just the area you want to check for doubles, but in this case it doesn't really matter) and press W > Remove Doubles.

  • No face on the top loop, creating non-manifold topology:

    It's a bit hard to see, but if you select it with AltRMB and translate it, it's a bit more obvious:

    enter image description here

    You can select non-manifold geometry with CtrlAltShiftM.

Example .blend
