I've an object with edges that appear to be connected to a face, but when you move a faces touching the edge, it leaves a hole in the object:

enter image description here

I would expect the top and side faces to 'stretch' with the selected edge, when I move the selected edge (just like the bottom one).

This shape started out as a cube. I used only 'subdivide', moved edges to where I wanted them to be and tried the 'edge split' modifier. (what did I (likely) do wrong to create this mess?)

My question is: How do I repair the object?

This was caused by the Edge Split modifier, which, as its name infers, split your mesh at the edges. To fix it, select all the vertices and click the "Remove Doubles" button in the Tool Shelf.

  • $\begingroup$ If I do want the effect of the 'Edge Split' split modifier, but do not want to actually split the edges, could I just set the modifier but not apply it? or is that not how modifiers should be used? $\endgroup$

  • $\begingroup$ Right, just don't apply the modifier. Modifiers are non-destructive until you apply. $\endgroup$
