# Fix intersecting faces in blender

I have a complicated geometry with some really small (not very visible) self-intersecting faces to fix, like below:

I have tried to use the shrinkwrap modifier and wrapped a fine-meshed cube on its surface. However, even though the cube is very finely meshed, the approximation is still not good:

I can use remesh modifier to fix the self-intersecting faces, but it requires an astronomical amount of vertices (deep octree) to maintain the geometry.

• There is no way to automatically fix overlapping faces, I guess, and even a function hiding all but intersecting faces won't help, since most times you need to see the rest of the mesh to fix those errors, but since you have just a few of intersecting faces, to better find/fix them manually, you could hide large parts of geometry (Hkey), allowing better visualization to smaller corners. Then fix, unhide (ALT+Hkey) and repeat. – m.ardito Sep 20 '16 at 7:35
