I’ve created a mesh and accidentally extruded polys without any thickness.

And when I try to extrude this polygons(to create a panel) they are extruded in both direction.

How to fix this? I don’t wish to merge polys and recreate this part 
Help please!
I know the problema long time ago also, vague remembrance at suspect:
maya flip face normals
Normals are not the problem. The problem is how to get rid of that unnecessary polygon which causes the problem.
Anyway thank you for your reply.
So if you have extruded with no distance then you just have verts sitting on to of each other…
select the verts on that part of the mesh and do a merge verts with a very low threshold (something like 0.001) this should keep the original shape but get rid of the double faces.
You would prob want to check your normal direction after.
I’ve tried to merge verts and although thought that it will resolve the problem but it didn’t. You can try it by yourself by creating a cube without a thickness. Merge verts and see that even with only 4 verts there is 2 polys :). I also tried to conform\reverse normals, delete history and still nothing. The only working way is to delete those polys one by one. But when i tried this trick on the panel where the problem arised it didn’t worked. Rather than select only one poly it selects 2 polys in some places. I don’t know how to deal with it. I had no such problems while using 3d max :rolleyes:.
I think the way to pretend such problems is to stop using two sided lighting. So you can see unnecessary geometry when you just created it rather when the history is deleted.
But still the problem is unresolved how to deal with it if you already stucked in it and the history is deleted.
Thank you for your replies!
